The following guide is a comprehensive tutorial on GPU mining from planning through execution. It will cover not just the technical setup but the decision making and process regarding profitability and long term gains. Table of Contents: 1) Planning 2) Hardware & Equipment 3) Environmental Considerations 4) Assembly 5) OS & Mining software 6) Wallet Storage 7) Conclusion 1. PLANNING 1.1 What to mine 1.2 Electrical costs 1.3 Profitability & ROI 1.4 Up-time 1.5 Monitoring & Alerts 1.6 Scalability 1.1 What to mine Not all GPU’s are created equal. Some GPU’s mine certain algorithms/coins better then others. For example, NVIDIA GPU’s are better at mining Zcash while AMD GPU’s are more successful mining Ethereum. It is important to decide what you want to mine before purchasing or sourcing your GPU’s. Currently Ethereum is the most profitable coin to mine however at some point it will go from Proof of Work (mining) to Proof of Stake. At this point those mining Ethereum will need to move to another algorithm. The good part about GPU’s is that unlike ASIC miners, they can mine any algorithm (although some more successful then others). So switching gears is not as difficult as one might think and we should see future coins using the Proof of Work model. Find out if it's profitable to mine Bitcoin, Ethereum, Litecoin, DASH. (ETH) Ethereum Classic (ETC. How to Identify a Bitcoin or Ethereum Cloud Mining Scam? As of the writing of this guide (Sept 2017) Zcash or Ethereum is the way to go. There are also multi mining pools and platforms such as that will pool your GPU Hashing power and automatically switch to the most profitable coin. Here are some resources to help you make an informed decision. Reddit, Steemit, and of course the BitCoin Pub mining section are all great resources to ask questions for up to date awnsers. Mining is not static! It is evolving monthly. So if you are unsure post a question! 1.2 Electrical Costs When it comes to mining, there is more to consider then simply how much coin you can mine in a given period. GPU hardware running 24/7 consumes quite a bit of power. If you dont factor in your electrical costs you may actually be losing money when your utility costs monthly are higher then the amount of coin you are mining. Power costs fluctuate DRASTICALLY depending on where you are in the world. In some areas, it may not be profitable at all to GPU mine. I live on the U.S. East coast where power costs are pretty inexpensive 0.10 KW/h. You can find your power costs on your utilities bill or by calling your electric company. In many areas electrical costs are negotiable! In the united states many states have deregulated energy and you can by power through a re-seller at a discounted rate. Before mining look into energy reseller alternative in your area. To determine if GPU mining will be profitable, enter your power costs and hash rates into this calculator: Find out what your expected return is depending on your hash rate and electricity cost. Find out if it's profitable to mine Bitcoin, Ethereum, Litecoin, DASH or Monero. Do you think you've got what it takes to join the tough world of cryptocurrency. 1.3 Profitability & ROI When mining, there are 2 important factor. How long will it take for you to get a return on investment (ROI) and how profitable is your mining operation. It is important to be conservative when doing these calculations as your GPU mining rig will become less profitable over time as the mining difficulty increases. Your ROI is very simple. How Many days will you need to mine to reach profits that equal your initial hardware investments. Here is a basic example. Hardware Costs: $3000 Total Hashing power: 230 MH/s Total Power Consumption: 800W Daily profit: $12.25 $3000/12.25 = 245 Days to ROI* Additionally, These GPU’s we use to mine are extremely powerful and great for gaming. These cards have excellent resale value and there is a large market for them. After 12-24 months you can conservatively resell the cards for 20-50% of their retail value to help offset the difficult increase and claim your ROI. Profitability is the second factor and there are 2 considerations. How much coin you mine and the interest/market growth of that coin. You obviously will want to mine as much coin as possible, which we’ve covered in the “what to mine” section. But we also need to consider the long term growth of the coin we mine. Some mining pools will allow you to be paid out in BitCoin. This may be helpful if you plan to invest your profits in to alt coins. You also want to be smart with how often you take your mining payouts. You may be charged fees per payout or fees for payouts under a certain threshold. You want to avoid transaction fees cutting into your profits. Best practice would be to read all the guidlines on payouts and fees from the mining pool you are using and to take payouts infrequently either monthly or quarterly. You may find you will be much more profitable taking payouts less frequently and you may see more growth with your profits coming out in BTC or investing in an altcoin you believe in (NEO, OMG, TenX, Monero, etc) 1.4 Up-time When it comes to mining, NOTHING is more important then up-time. Every minute your mining rig is offline you are losing money. So it is CRUCIAL to build redundancy into your design as well as invest in materials and testing to repair your rig if/when something fails. As with any 24/7 operation, you’ll need to weed out single points of failure. Some considerations are: -GPU failure -PSU failure -Motherboard failure -Peripheral failure -OS corruption -Power outages -Internet outages GPU Failure: The most common failure in a mining rig is hardware. By design, mining rigs have multiple GPU’s, so we don’t need to worry about redundancy there as you will already have 5-10 GPU’s per rig. It is important however to thoroughly review the warranty and RMA process for your GPU hardware and contact manufacturer support so that when the time comes you know the steps and the process to get your GPU replaced. MotherBoard Failure Motherboards are durable equipment without many/any moving parts that typically either fail out of the box or are durable for the lifetime of the board. That said, if your motherboard does fail, you are going to be losing money every second it is offline. Another consideration in larger mining rigs (6 or more GPU’s) is running all your GPU’s off of one motherboard. I think it is wise to shy away from motherboards with 10-18 PCIE slots. If your motherboard failed and you were running 16 GPU’s on it your ENTIRE mining operation would go offline. Where as if you had 2 motherboards if your board failed you would still be able to mine half your GPUs while the other is being swapped out. Motherboards are stocked in many computer stores and readily available with next day shipping from most online resellers such as Amazon and NewEgg. However you want to be able to quickly swap out a bad board to limit mining down time. With the relatively low cost of motherboards ($50-80 in most cases) it is wise to invest in a second motherboard. Be sure to always test your backup hardware. A backup motherboard does you know good if its DoA/a lemon and you realize your mining rig will still be down. So test that backup hardware! Peripheral failure: Like with motherboards, you dont want your mining operation to go down because your hard drive failed, PCIE risers failed, or you have a bad cable or RAM. These peripherals are inexpensive and you should plan to have a spare on hand of each peripheral. PCIE risers in general are susceptible to failure overtime. For less then $60 you should be able to have a replacement of all your peripherals. As a wise man once told me “It is better to be looking at it, then to be looking for it” OS Corruption: It is not uncommon, especially in Windows builds, for the OS to become corrupted or other software/OS issues to can cause downtime in your mining rig. There is a simple way to combat OS corruption. Backup or clone your hard drive. Once you have your rig fully configured and mining either clone your hard drive or make a backup image. There are plenty of free or low cost options for cloning or imaging software such as Acronis True Image and EaseToDo Cloning software. I personally like to clone my drive to a spare drive which protects against both OS corruption AND hard drive failure. It is also a great practice to either record your GPU/hardware/software settings or if your drivers allow it export the settings or export a profile so you can easily restore it if needed in the future. Power & Internet outages: Power and internet outages are mostly out of our control. But there are steps we can take to minimize the impact. It is strongly recommend to have your mining rig plugged into an uninterruptible power supply(UPS). A small APC UPS can be purchased for as little as $30 even cheaper if purchased through secondary markets. While the UPS will NOT keep your mining rig up during a long power outage, it will afford you the time to gracefully power down your rig so that an unexpected power outage does not cause a surge or damage to your GPU hardware. Internet outages will also halt your mining operation. It is a good idea to have a secondary cheap router on hand in the event your router fails. A router can be purchased on the secondary market for as little as $5 or $10. While you CAN get a redundant secondary ISP, it is not worth the cost as this will incur more monthly recurring costs cutting into your profits and ISP up-time is generally in the 97-99% range. Instead it may be worth while to have a second site/location you can bring your rig too during an ISP outage or disaster (a flood or fire at your current location for example). 1.5 Monitoring & Alerts Having built in redundancy and a good disaster recovery plan are great steps to ensure your mining rig stays up and online. But all that planning wont help if you dont realize your mining rig is down. It is important to setup email or text alerts anytime your rig is down or stops mining. Most mining pools have a built in function that you can configure to send you a text or email alert anytime the pool detects you stopped mining. Likewise you can should set alerts with in windows, your UPS, any any other hardware capable of denting outages so you can quickly resolve the issue. Please use the forum to help with any questions on configuring hardware, software, and service alerts. 1.6 Scalability When planning your mining rig, it is important to consider how you may want to scale the operation in the future. Building the infrastructure of your rig in a modular way allows you to scale the build more easily as well as upgrade components over time if necessary. Building a stackable rig for future implementation is important when discussing scaling. Designing a Bottom shelf with clearance and airflow for example is important if you plan to stack a second rig on top of the first one. Another important consideration is your space. Do you have the space to grow your operation physically? Do you have the appropriate cable lengths and network infrastructure to grow the rig? Do you have the proper cooling environment to handle a large scale operation? This planning should be done prior to the purchase, buildout and implementation of any rig. Pro-Tip: Check out post on electrical requirements. HARDWARE & EQUIPMENT 2.1 Open Air frame 2.2 GPUs & PSUs 2.3 Motherboard and perifpherals 2.4 Cable Management 2.5 UPS 2.6 Environmental protection and cooling 2.1 Open Air Frame Other then your GPUs, your frame may be the most important thing your purchase and design. Temperature control, cooling, scaling, repairs, and upgrades are all heavily reliant on a well assembled well designed open air frame. While your rig doesnt need to be pretty or a Picasso-like work of art it does need to be functional and allow for cooling, growth and maintenance. The best open air designs seperate components out, allow for proper air space, and are designed in a way that you can easily get to all component in the event in which they nee to be swapped our or repaired. There are a few considerations here and while there are dozens of great designs I will be presenting one in which I believe covers all the bases, You’ll want to choose a good material: -Something that conducts heat well -Something that is light and can be easily moved -Something that is cost effective -Something that isn’t prone to produce dust or particles Lightweight metals such as aluminum are a great choice. Aluminum tubing and aluminum angle are lightweight, cost effective, available at most hardware stores, and dont produce dust or particles that may get sucked into a fan intake. While aluminum angle is easily assembled, I prefer the modularity of aluminum tubing with connectors. Is a great online source for aluminum tubing and connectors. The snap in connectors make it easy for anyone to quickly assemble a sturdy box-type frame. The materials can but cut to custom sizes and is fairly inexpensive. I built a 24 X 18' custom cut 2 tier frame for less then $65 including shipment. A good open air rig is more then just the box frame. You will want to have 2 tiers. An upper tear for your graphics cards and a lower tear for your motherboard, peripherals and power supply. The bottom shelf should be sturdy and be braced. This will reduce vibrations which can lead to wear and tear or damage over time. As you can see from the photo above we attached 3 pieces of 1/4' thick aluminum across the bottom of the box frame to help brace the shelf. For the shelf you want to use something sturdy. We chose a 1/8' piece of stainless steel sheeting. This has the weight to remain sturdy and reduce vibration from the equipment running on it. Since this is our first rig there was no consideration for air flow on the bottom shelf. However if this was a second rig, we would instead use a perforated steel sheet for airflow for the GPUs stacked on the rig below. You will also want to stabilze your components. Drilling motherboard standoffs into the steel base will allow to attach your motherboard and provide airspace for it so it doesnt come in contact with the steel which could cause a short. You can also use the Aluminum angle to create a bracket to hold your PSUs in place. The Top Shelf should have a ledge or flange for the GPU to screw into as well as a rear crossbar to support the back of the video card and hold it into place. To achieve this you can attach a piece of Aluminum angle across the frame. 2.2 GPUs & PSUs GPUs and PSUs are the most important hardware components of your mining rig. For GPUs there are several considerations. We already covered “what to mine” in section one and will now focus on which GPUs are the most reliable and profitable for current and future mining. There are 3 major considerations: -The initial investment (Cost of the GPU) -The Hashrate vs Power consumption Ratio -The long term mining ability. Initial Investment How quickly you reach your ROI is directly proportionate to how much you spend for GPUs. While GPUs are still somewhat tough to source at cost/without a market things have settled down to where you can find most cards retailers or through online stores. While one GPU may drastically outperform another, it may make sense cost wise to go with another GPU. For example if you are able to buy TWO GPUs with a 18 MH/s output for $20 each that may be a better option then buying one card with a 35 MH/s rate for $500. So keep initial cost of hardware in mind when making this decision. This will vary quite a bit depending on where you live and what options are available to you at the time. Hashrate vs Power consumption Ratio There are a few different philosophies on Hash vs. Power Consumption which are influenced not just by opinion but by area. If your power costs are low (or free) Hashrate become most attractive. Additionally with difficulty going up over time, hashing as many coins as possible in the early stages is also a consideration. If you live somewhere with high power costs, power consumption becomes critical. For this guide we will assume all things are equal. Below is a chart of viable GPUs from a Hash vs. Power perspective sorted by hashrate (no necessarily by best ratio) AMD Radeon R9 295X2 - 46 MH/s @ 325 W AMD Radeon RX VEGA 64 - 40 MH/s @ 165W NVIDIA GTX 1080 Ti - 32 MH/s @ 125W NVIDIA GTX 1070 - 27 MH/s @ 105W AMD RX 580- 22 MH/s @ 75W AMD RX 480 - 20 MH/s @75W *** Disclaimer. These rates are subject to change and may vary based on driver and bios configurations. There are tons of resources on hashrates. Please do your own research and check the mining forum for real life results people are getting. *** I’ve personally tested both the GTX 1070 and AMD RX VEGA. I find these to be the most measurable, cost effective GPUs that provide high hash rates with reasonable power consumption. Please check out my AMD RX VEGA mining rig breakdown here. Finished building my new open air frame. No longer on the rickety wooden shoe rack of a rig Aluminum tube frame with aluminum angle holding the back of the cards and a stainless sheet on the bottom shelf didnt seem right all silver and blah so i gave the frame a coat of metallic black and some cherry red on the steel to make it match the VEGA’s More pictures to come Were mining at 215.75 MH/s @ 1055W the HP server power supplies are ton more efficient then the gold PSU we The RX Vega and GTX 1070/1080 are both great long term mining options. There may be better alternatives or better options based on your situation (Budget,environment, power costs). Please do your research or consult the forum to help make this decision. Long term mining ability. Just because a GPU mines well now does not mean it will continue to mine well in the future. There are 2 major considerations when considering long term mining ability. Difficulty and Dag. Over time as coins are mined the difficulty of the algorithms increase. This is a sort of check and balance put in place on the block chain to ensure the security of the ledger and that no single entity can manipulate the blockchain. For more on this, read the bitcoin white paper or read up on how proof of work functions. The important thing to keep in mind however, is that the difficulty WILL increase. So you will want as much hash power as you can get. Whether that is achieved with scale (many GPUs) or Raw power (GPU hash rate) you want to try and squeeze as much hashrate as you can out of your rig while remaining profitable in respect to power consumption. The second, and more important consideration is the DAG (Directed Acyclical Graph). The DAG basically maps out the algorithms and instructions. It must be loaded into memory almost like a header. Why is this important? Because the DAG grows at each increment. These increments are called “Epoch” and come in 100 hour increments. At a certain point, a GPU will not be able to fit the DAG into memory this takes quite some time, however in the near future (at approximately epoch 199 or 200) cards with only 4 GB of GDDR5 RAM will no longer be able to handle the DAG and will not be able to mine Ethereum. Additionally, as we approach Epoch 200, the DAG will consume more and more of that 4 GB of RAM cutting into the hashpower of 4 GB GDDR5 RAM GPUs. What does all of this mean? In Short: Make sure your GPUs have 8 GB or more of memory. One consideration of going with the AM RX VEGA was its 8 GB of HBM2 memory. RX 480/580 card models with 4 GB of memory are now flooding the secondary market. If you plan to mine, stay away from those 4 GB models. PSUs are the other important hardware component. This is not only going to power your rig and keep it online, but also factor into your energy costs. All PSUs are not created equal. Some are much more energy efficient then others. It is also important to understand how much power your need. There are 3 major considerations when choosing a PSU: -Durability/output -Efficiency -Cost Durability/Output If your Rig is going to draw 1000W you dont want a 1000W power supply, you want more juice then that as PSUs are not designed to run on their maximum load 24/7. You can refer to this site to help calculate your power consumption and how big of a PSU you will need. !!!THIS IS A MUST READ IF YOU PLAN TO MINE OR CURRENTLY MINE!!! I’ve been reading on a lot of different forums (prior to TheBitcoin.Pub) and even on our own forum about people not knowing the electrical needs of their GPU mining rigs. I’m here to tell you that and I have spent a lot of time researching and implementing what it takes to get multiple rigs up and running. We have contacted electricians and even consulted with electrical engineers. This information is GOLD please stick with Efficiency PSUs are typically rated into 4 categories: Bronze, Silver, Gold, and Platinum. Bronze being the least efficient and Platinum being the most efficient. Why is this important? Because the more power you waste/use the less profitable your mining rig will be. PSUs convert AC current from the wall and convert it to DC power for your rig. During this conversion there will some power loss. This also produces more heat. The higher efficiency power supplies require less AC current to produce the same amount of DC power and produce less heat. (which is also important as many GPUs hash better at lower temperatures). You can Save 5%, 10%, or even 20% on energy costs with a Gold or Platinum PSU. Resource: Cost The last factor is cost. PSUs, especially the gold rated ones, can cost up to $200 or more. The more you spend on a PSU, the more profit you need to make to reach your ROI. And as mentioned in the Redundancy/Single point of failure portion of Section 1 above, you are going to want to have multiple PSUs in your mining rig. So choosing the most cost effective PSU and balancing that vs. The most efficient PSU is an important calculation. Instead of purchasing an expensive high end gaming PSU, purchase an old server PSU. Server PSUs are built to run 24/7, are platinum rated, and are very inexpensive ($15-$35). You can purchase a Pair of 1000-1200W PSUs to power your GPUs and a 225W PSU to power your motherboard all for under $100. Sells HP proliant PSUs here: Important! You will also need a breakout board. Server PSUs attach modularly to server motherboards. In order to get 6 pin PCIE interfaces you will need a breakout board. The X6 breakout board is available on both ebay an parallel miner: 2.3 Motherboard and peripherals Purchasing the right motherboard is very important and it is easy to mistakenly buy something that appears to meet the needs of your mining rig but falls short. For example, a 6 card mining rig will require 6 PCIE slots in order to run all 6 cards. There are plenty of motherboard that come with 6 or more PCIE slots. The problem is a lot of these motherboard are not made to handle 6 GPUs running simultaneously and while they can run 6 PCIE devices at the time they weren’t designed with GPU mining in mind. They were designed to handle a couple of graphics cards in addition to other PCIE devices such as RAID controllers, NIC adapters, Card readers and other PCIE interfaced hardware. Luckily, with the expansion of GPU mining, hardware manufactures have started making motherboards specifically geared towards GPU mininig, ASRock, BioStar and others make several boards designed to handle 6+ GPUs, and even have “BTC” in the model name. While you don’t need a motherboard marketed as a “BTC” or “Minining” motherboard to run your rig you should do extensive research on whether or not the motherboard you choose can handle the GPUs and has shown to be stable running multiple GPUs 24/7. Resource: The following is a list of some of the more popular mining motherboards: 7gpu motherboard, 8 gpu motherboard, 6 gpu motherboard, mining motherboard, z170 7 gpu, best gpu for ethereum 2017, asus h170 pro gaming. As mentioned in section 1 with regards to redundancy and uptime; I would suggest against motherboards with 10+ PCIE slots to run that many GPUs all on one board. Not because the board can not handle it, but because if you do have a motherboard failure you bring your entire operation to a halt. Now that you have all the main components of your rig mapped out, its time to look into the peripherals, bells, and whistles you will need to connect all the components and optimize your design. At a minimum you will need: -PCIE Risers -PCIE/Molex/Sata connectors. -Hard drive/storage -RAM/Memory -Processor PCIE Risers are extension cables that connect your GPUs to your motherboards PCIE slots. Remember the reason we are building this open air rig is for cooling and airflow so housing your GPUs right in the motherboard would not allow for that cooling and likely overheat your rig. The risers allow you to secure the GPUs on the upper shelf, where air can flow more freely. There are alot of PCIE risers on the market and most of them are made cheaply and are the component most prone to failure in your rig. It is recommended that your purchase a few spare risers so you minimize downtime in the event of failure. PCIE risers come in both powered and non-powered versions. It is recommended to use the powered versions over the non-powered 16 pin ribbon cables. The powered versions require less power from your motherboard and from a durability perspective are going to keep you up and running longer. The powered versions are also required for many rigs as most multi PCIE slot motherboards dont have full 16 pin PCIE slots for of their interfaces. PCIE/Molex/Sata cables Most PSUs and GPUs will come with cables and connectors. But you may not have enough cables to connect all your GPUs or more important connect them all with individual cables. (Running more then 2 GPUs in series is not recommended and likely to cause issues down the road). If you go with the above recommended route of using HP server PSUs with breakout boards, you wont have any cables included and will need to purchase several 6 pin to 6+2/8 pin cables/connectors. Overall you will want to do a review of all the cable and interface/adapter needs for your components and make sure you have all the required cables. You will also want a few spares for troubleshooting or replacement and most importantly be sure to get the correct lengths so that your cables reach your hardware and arent being stretched. Hard drives/Storage GPU mining rigs require minimal storage. You will need a drive to run your operating system and GPU hardware. Windows 10 requires 16 GB of drive space for its installation. With software and formatting you can easily get away with a 64 GB hard drive for a windows OS based mining rig. Linux based rigs can run on even less or even run off a usb stick. 64 GB 2.5' or mini PCIE hard drives can be purchased for as little as $35. As mentioned in section one, buying a second drive and cloning your rig after initial tested stable setup or having a backed up.ISO image ready to go for recovery is strongly recommended. RAM/Memory While GPU RAM/Memory is crucial to the performance of your mining rig, system RAM/Memory is not critical at all. A 4 GB stick of RAM will be enough to power your rig without any issues. With the cost of RAM being so inexpensive, and for redundancy reasons, it is recommended to buy two 4 GB sticks of RAM, keeping your rig operational should one stick fail. A 2 x 4 GB RAM kit will run you as low as $30. Processor Like system RAM, mining rigs do not require A lot of processing power from the CPU to operate. In fact, it is more profitable not to run a powerful CPU as it wont increase mining performance but will increase your power costs. Using a Pentium or Celeron processor is going to provide all the processing required while consuming less power then an i3/i5/i7 processor and also save you quite a bit of money in hardware costs. Be sure to keep this in mind when choosing your motherboard to ensure the socket can handle the processor you choose. 2.4 Cable Management Cable management should be considering for any mining operation, especially larger multi rig operation are those expected to scale overtime. Beyond just satisfying those of us who are OCD when it comes to organization, proper cable management while allow you to more easily access components or swap hardware in and out more efficiently. As we have covered several times already, you are losing money every moment your rig is down. To e able to quickly swap hardware and cabling in and out is an important design consideration. Some best practices for cable management include: -Use cables of appropriate length, with enough slack to prevent pulling but not so much that it will coil up and tangle. -Use velcro in place of tie wraps whenever possible. Velcro allows for easy removal and recabling where ties need to be cut. -when cutting the excess of a tie wrap, be sure to cut right at the knuckle to avoid sharp edges that could cut wiring -use your frame to secure and space your cables out evenly and channel them to the appropriate areas. -Avoid crossing cables across the rig, and design your rig so that components connected with cables are closest to eachother. 2.5 UPS A UPS (uninterrupted Power Supply) is strong recommended for all mining rigs. A UPS will NOT keep your mining rig running through a power outage what it will do is allow you to gracefully and safely shut down all the components of your mining rig so that a power outage and sudden shutdown will not damage any of the components. Protecting your investment is critical. You dont want to be caught setting up an RMA or warranty claim on a GPU that failed during a power outage nor do you want your rig down while you wait 7-10 business days for a new one to arrive. A 1500W power supply can be purchased for as low as $65. Most UPS also have the ability to set up email or text alerts that will notify you of an outage which is a nice feature to have. 2.6 Environmental protection and cooling Once you have your rig set up and running it is important to protect your rig against its surroundings. Depending on where you store your rig, you may need to worry about things such as dust, debris, moisture,and other elements. Some considerations and failsafes to consider are: -to keep your rig in a cool, dry area. -keep your rig elevated off the ground in the even of a spill or flood.whether on a shelf or even building your frame out with legs to elevate the shelves. -To protect against dust and debris you can line the frame of your rig screen door screen which will allow air flow while cutting out dust and particles. Covering fan intakes with pantyhose is an old IT hack that many people still employ that also keeps dust and particles out. -Use compressed air to blow any dust or debris out of your rig on a periodic basis. In addition to keeping your rig dry and clear of debris, proper cooling is also important especially in larger scale multi rig mining operations. While the subject of cooling is vast and beyond the scope of this guide it is important to know that keeping your rig cool is critical not only to keep it from overheating or causing damage but a lot of high end GPUs will also have increased hash rates at lower temperatures. Channeling heat away from your rig with duct or tubing, fans, or vents can make a considerable difference in how cool your rig will run. While air conditioning is a very effect way to keep your rig cool, be sure to consider the power costs of running air conditioning 24/7, as this may cut into your overall profits or even put you at a loss depending on the power consumption of the air conditioning and electrical costs in your area. ENVIORNMENTAL CONSIDERATIONS 3.1 Where to store your rig 3.2 Power requirements 3.3 Building to Scale 3.1 Where to store your rig Choosing where to store your rig is important as the environment will be integral in ensuring that our operation stays online and is protected against hazards. Like any electrical equipment, it is best to keep your rig in a cool dry place to prevent against moisture damage or overheating. You’ll want to store your rig somewhere with: -Ample space for airflow -Good ventilation -temperature control -free of dust and debris You’ll also want to keep your rig elevate off the floor to protect against any floods and potentially enclose your case to protect against debirs. This will be covered in more detail in the hardware and assembly sections of this guide. Electrical Wiring - Most houses are build using 14 AWG electrical wiring. 14 AWG electrical wiring is designed to handle electrical loads up to 15 amps per building codes. Any amperage over that will cause the shield around the wires to melt due to heat. If you are using a 1500watt PSU, it is probably rated for a 15amp input. So you are probably thinking, “I’m good”, no. That maximum load on the wires isn’t made to handle that load 24/7. Typically, electrical engineers would recommend only going to about 80% of the full load. Also, lets say you want to run multiple GPU mining rigs in the same room, you MUST verify that all the outlets in the room are ran in parallel and not in series. Layman’s terms, each outlet directly feeds back to the breaker box. Otherwise your rigs will be running on the same circuit and you will overload the wiring and the breaker. Consult with a certified electrician about installing 12 AWG electrical wiring on 20 amp breakers if you are going to build more than one GPU rig. Extension cords - PLEASE DON’T USE EXTENSION CORDS! Read the warning labels on the extension cords. They are not made to handle the continuous load that the GPU mining rigs demand. Extension cords are designed for temporary use only. I have seen extension cords overload or malfunction and pop (Christmas 2016). The complete guide can be found in the Mining & Hardware support forum. !!!THIS IS A MUST READ IF YOU PLAN TO MINE OR CURRENTLY MINE!!! I’ve been reading on a lot of different forums (prior to TheBitcoin.Pub) and even on our own forum about people not knowing the electrical needs of their GPU mining rigs. I’m here to tell you that and I have spent a lot of time researching and implementing what it takes to get multiple rigs up and running. We have contacted electricians and even consulted with electrical engineers. This information is GOLD please stick with 3.3 Building to Scale When considering your environment, it is important to plan things for future growth if you intend to scale the operation. The needs and requirements to run 25-50+ GPUs is drastically different then running just 5 or 6 GPUs. Your electrical infrastructure, storage, cooling, and potentially even zoning and permit requirements will need to be planned in accordance with how large your operation may grow. It is recommend to consult with an electrical engineer and potentially even your town or city for guidelines on scaling your operation to something of commercial size and power needs. ASSEMBLY 4.1 Frame assembly 4.2 Prepping for components 4.3 Component installations 4.4 Cabling 4.5 Disassembly and testing 4.6 Customization 4.1 Frame Assembly 'Measure 10 times, cut once' -Someone really smart This old proverb needs to be running on loop in your head the entire time you assemble your frame. Spacing out your frame to properly hold your GPUs is really important. You need to make sure your GPU measurements as close to exact as possible when ordering/cutting your material lengths. If you are using the above recommended tubing and connectors from “Esto Connectors” you need to be sure to factor in the 3/4' added to the length by the connectors. It may also be worthwhile to make a full scale model out of scrap wood or cheap plastic to make sure you get the measurements right. When building my first rig, i used some left over 1 x 1 pieces of wood left over in my garage to build the top shelf of my rack to get an exact measurement for the spacing on my GPUs. Once you have your prototype it is easy to get the exact material lengths and purchase or cut those materials. From there it is just some screws and/or elbow grease to get your frame assembled Once assembled, verify once more that your components and GPUs will fit properly. The last thing you want to is to start cutting/installing shelves and brackets to find out you made a cutting error and it wont all fit right. 4.2 Prepping for components While most of the hard work is measuring and building the initial frame, there is prep work still needed to properly install your hardware components. You’ll need to consider the following: -Screw holes will be needed to attach the front of your GPUs to the frame and hold them in place -A rear support will be need to support the weight of the GPUs -Braces and a bottom shelf will need to be installed to hold your motherboard and power supplys -motherboard standoffs will be needed to secure the motherboard and rise it above the shelf -angle brackets are a great way to secure PSUs into place Before drilling the screw holes for your GPUs, space them out and mark where they will all go to ensure even spacing and proper airfflow. Using a cardboard template of the width of your GPU can be helpful in this instance. Once marked drill the holes to the width of the screws you are using (i used #6 machine screws). After drilling each hole, secure the GPU to test fit and angle. Then remove the GPU and move on to the remaining screw holes. While some designs will use the frame itself to support the back of the cards, you may want to install something a bit more modular that can be more easily adjusted. A piece of aluminum angle installed horizontally across the top tier is a great fit to support the rear of the card while maintaining some flexibility should end up swapping out GPUs or add additional GPUs with a different form factor. Some designs will support the GPUs by using shelves with PCIE risers secured to that the GPUs plug directly into. This is a really nice design however it does require a bit more building material and by eliminating a shelf under the cards you allow for closer to complete 360 degree air flow. Now that we have our upper tier designed and assembled, we need to work on the lower tier which will house or motherboard and power supply components. As mentioned in the above sections, minimizing vibrations of these components helps prevent wear overtime as well as keep your sanity by eliminating the constant noise. In our design, we used 3 pieces of 1/8' thick aluminum to brace the the lower shelf: For the lower shelf itself, using a heavy metal, like stainless steel can help keep the shelf secure and free of vibration. We used a 1’8' thick piece of stainless steel sheet. You can secure the sheet to the frame with self tapping or machien screws, but the snug fit and weight alone was tight enough and vibration free as is. With our shelf installed, we need to create the ifrastucture to secure our Motherboard and supplies. A short piece of aluminum angle spaced out to the width of your PSU is a good choice to secure it in place. We used industrial strength adhesive to attach our angle, Last we used 1/4' CPU standoffs (female on both ends) as a base to hold our motherboard in place. Carefully mark your bottom shelf where the 4 screw holes for the standoffs will need to be drilled in the bottom shelf. From there simply drill the holes and attach the standoffs from the bottom with screws. This will allow you to install and secure your motherboard later on. Once you’ve secured everything in place, you are ready for cabling. 4.4 Cabling Now that everything is secured to the frame its time to begin installing our cabling. It is important to make sure all cabling is proper lengths, reaches without stretching and without too much slack which can cause tangles and make it difficult to troubleshoot later. Attach your cables, one at a time moving inside out. This well prevent your cables from crossing between each other. Use velcro to attached your cabling to the frame or any fasteners you have installed. Once you got all your cabling complete, you are ready for some testing. 4.5 Disassembly and testing Before you beggining your OS and software installation its important to do some testing and to disassemble your rig Making sure your rig POSTs and your bios is recognizing all your GPUs is an important step before finalizing your physical installation and moving your rig to its final destination. Once it POSTs and sees all your hardware, you are in a good spot to proceed forward. If it doesn’t you can easily troubleshoot the issue while everything is easy to get to. You will next want to know ahead of time how to take everything apart and reassemble it so that when you need to troubleshoot or make repairs down the road you’ve weeded out any issue that prevent from quickly swapping out components. This will also allow you to make any last minute customization or bells and whistels. 4.6 Customization With our rig ready to go into OS/software installation and the physical assembly completed and tested its time for any last minute customization, tweaks, bells, whistles, and branding. A $2 can of red spray paint for instance can go a long way to make your rack stand out a bit from the cold drab wire racks you’ll be sitting it in for the next year, For our build we gave all the aluminum and steel a coat of red so our frame matched the black and red theme of the AMD RX Vegas that the rig would power. OS & MINING SOFTWARE 5.1 Operating System 5.2 Drivers and firmware 5.3 Mining software 5.4 Tweaking and testing 5.1 Operating System Mining software can be run on multiple platforms and operating systems. Windows 7/8/10 are all supported by most mining software and pools. In addition several linux distobutions also have support including customize OS with the mining software built into it such as. While it is beyond the scope of this guide to cover the installation of all operating systems we will cover some of the considerations on choosing an operating system and best practices for installation. A windows installation or stand alone Linux install will allow for more flexibility then running say EthOS as you can install several different mining softwares and switch based on profitability and stability. However if you just plan to mine one coin, using something like EthOS is likely to be more stable. The profitability really will not fluctuate much and this is more of a user preference, although i do personally prefer a windows installation due to all the reporting and alerting i can do and find it easier to tweak drivers settings within windows OS. Prior to installing your operating system, its best to update the firmware of your BIOS, as doing this after a windows installation may cause some issues or you may have to re-do any settings or configurations. Once complete, you can move forward to the OS install. 5.2 Drivers & Firmware Once you’ve chosen and installed your operating system, it is important to update all of your drivers, firmware, and get the most up to date versions of software that support the hardware you are using. While most hard ware will work “out of the box” with OS drivers, up to date versions will be more stable and allow for more tweaking. In our build, going from the default VEGA drivers to the updated AMD mining drivers saw a 20% increase in hashrate and considerable reduction in power consumption. This drastically increase the profitability of our rig. You may want to steer clear of alpha/beta or non confirmed drivers and software unless they are the only ones that provide support for the hardware you are using. These pre-stable release versions can cause crashes and downtime for your rig. Once you have a working set of drivers, and a stable environment it is recommended to do a backup of all settings and/or do a full image backup of your hard drive. You dont want to be repeating this timely process again in the event of a system or hardware failure. 5.3 Mining software Once your rig is setup with an operating system and optimized with up to date drivers you are ready to install your mining software and start mining! There are several algorithms and coins to mine with GPUs as mentioned earlier in this guide and with that several different options for mining software. There are tons of great resources on installation and setup of mining software. The most popular/profitable are: Claymore dual miner (Ethereum + [coin]). Resource youtube, reddit, steemit, and right here in the Bitcoin Pub there are great resources for setting up and tweaking your mining software as well as choosing the most profitable option based on your hardware. Before you even begin purchasing your GPUs an mining hardware, install and test out the different mining software on your computer to see how they install and function. It is helpful to be familiar with them so that you hit the ground running when its time to install them on your rig. 5.4 Tweaking & Testing Once you have chosen and installed the software you are going to use it is CRITICAL that you test your software and HashRates with different settings. You can see DRASTIC changes in what your HashRate is in certain software based on your driver and bios settings. For example, simply changing the fan speed on your GPU can result in +/- 5 in hash rate. Take the time to do your due diligence. This is one area where holding your rig back from mining is profitable in the long run. Test your hash-rate/power consumption of your rig on every potential setting. When setting up our rig we literally adjusted every setting 1 unit at a time and retested the rate/power after each reconfiguration. A HashRate:PowerConsumption ratio so much better then what others had been seeing and reporting that people have called us out as liars until we confirmed with the screenshots and settings. We took a rig originally operating at 38 Mh/s| 355W per card to one hashing at 39.5 MH/s| 160W per card. We also found an alternative configuration of 43.5 Mh/s| 245 W per card. When you put that into perspective, that testing that took a week probably shaved a month off our ROI and increased our profitability by about 12-17% daily. Purchase an energy/power usage monitor. These are inexpensive and allow you to determine how much power your rig is using, how much your are spending daily/monthly on electricity and send power alerts if you reach certain thresholds or go offline. You can also use it to test the power consumption of your rig at different settings. We use one from. PROFITS & WALLET STORAGE 6.1 Taking Payouts 6.2 Crypto vs. Fiat 6.3 Storing Payouts 6.1 Taking Payouts Once your rig is up, stable,configured for your mining pool, and actively mining it is time to start thinking about what to do with your payouts. How and when you take your payouts will be a big factor in how much profit you make and how quickly you reach your ROI. Most mining software and pools will pay you out in the coin that you are mining. So for instance if you are mining ethereum, the pool will pay you out in ethereum. There are some pools and services however such as nice-hash which will pay you out in BitCoin or other currencies. So depending on how you plan to use your mined currency, you may want to consider one option vs. If you plan to convert all of your mined zCASH to alt coins, joining nicehash so you are paid out in BTC which can be easily traded with alt coins may be an attractive option for you. Conversely if you plan on keeping all of your mined zCASH as zCASH you are better off being paid out in zCASH. Another consideration is how often you take payouts. While it may seem attractive to get paid out as frequently as possible, the less often you take payouts the fewer transaction fees you will end up paying. Which over 12-24 months can add up. Additionally some mining pools/software will charge a higher fee for payouts less then a certain amount (i.e. Less then 0.1 ETH). You want to avoid these fees whenever you can. Monthly or quarterly payouts are recommended unless you are either really nervous about your mined coin living on the pool for that long or believe you can make more then the transaction fees trading your mining profits for alt coins. There is no right or wrong way to take payouts depending on your investment profitability and long term strategy on mining profits (holding them in the mined coin vs. But it is smart to calculate the costs and risks of taking more infrequent payouts with less fees vs. The alternatives. 6.2 Crypto vs. Fiat Prior to reaching your ROI, it may be intuitive to cash out all of your mining payouts/profits to US dollar/Fiat currency to pay back towards your ROI. Depending on your circumstances this may be the case. For instance if you bought some of your hardware on 6 or 12 month 0% credit offers and need to pay that back prior to getting hit with interest on the purchase, then applying that profit to Fiat/US dollar would make a lot of sense. Alternatively, the amount of profit you make could be drastically increased by keeping your mined profits in Crypto and earning compounded interest on that coin as the value of ethereum or other mined coins increases in time. Those who mine, and are involved in the crypto community typically project the market to increase over the next 12-24 months. If there isnt debt to be paid, keeping your mined profit in crypto is likely to increase your profits and help reach your ROI quicker. With any investment decision, doing your own research and factoring your own philosophies and risks is of the utmost importance. 6.3 Storing Payouts While you may already have a wallet for the coin you mine, it makes a lot of sense to create a separate wallet just for your mined coins. This will allow you to more easily tack how much coin you have mined and run any tools or reports regarding profit and projects to ROI. For instance, if you have an exsisting wallet with 10.43 Ethereum coins in it, having your mined payouts go to that same wallet may make it difficult to track how much Ethereum you mine over the long haul, especially if you cash out to trade some of that Ethereum. Resource There are several tools, apps, API integrations, and excel spreadsheets available right here in the bitcoin pub to help track your investments and profits. Redundancy is extremely important to any mining rig, and building in that redundancy to reduce downtime is crucial to avoid losses during hardware failure. Taking advantage of any free resources to help reduce ROI is crucial for anyone entering the GPU mining world. If you cans source PC components, building materials, software licensing or even run your rig somewhere with free power costs, your time to ROI will be drastically decreased. Lean on the community and The BitCoin pub for information and guidance. We have one of the most active and helpful communities right here in CryptoNation!

Thanks for the shout out. Yeah • Running on a MSI B250 PC MATE motherboard. EVGA supernova 650 Power Supply. No risers in the equation at the moment (But it happens with the risers in play too.) • One card is a PowerColor Radeon RX480 8Gb. The other is XFX RX480 8Gb. The cards look identiacal except one has a back plate and the other does not. • Currently Running Ubuntu 16.04 LTS, I’ve used EthOS as well. Driver is 1.2 AMD-APP • Mining software is ethminer No errors just reboots. I configured Ubuntu to restart mining on startup to keep things going. But like I said, sometimes after a reboot it will mine at a much lower rate for no apparent reason. If I could throw a limit into the command, it might fix it? Just curious if others see this happening as well? What is the draw on your power supply? Do you have meter to see how much you are using? You could potentially be seeing spikes beyond what your power supply can handle. Do you have the same issue with just 1 card? Or is it stable on 1 card? If it IS stable on 1 card is that true for both the XFX and the power color or is just stable for one of them? If it is stable for either card individually but no both, its most likely a power or heat thing. How hot are the cards running? Do you have anything to cool with? If you crank the air conditioning in the room do the crashes stop? The rig hashing different after a reboot isnt all that suprising. It could be either your card settings being reset after failure or a safety mechanism throttling the card. Does your mining software have any logs? Have you checked the ubuntu system logs? Step 1 should be determining if the problem happens with just 1 card or isolating the issue to 1 of the 2 cards. I have a Kill A Watt. Will that help me determine the draw on the PS? Or just the whole system? Maybe it’s the same. Yes, it runs 100% fine on just one card. Doesn’t matter which card either. I do have a separate personal barrel fan blowing down the cards. I see no temps on my rig sadly. On EthOS it did, and on ETHOS it ran the fans at nearly full tilt and yet it would still reboot. I’ll see if I can find some logs. Also, let me know if the Kill A Watt is really going to help here. I bought it to calculate energy use, but didn’t think it would help with troubleshooting. For the Kill-A-Watt its the same your power supply is basically the entire system. Thats what powers everything. What is it showing for power consumption? The fact that it runs fine on one card and it doesnt matter what card it is makes me pretty sure its a power or heat issue. Your 650W supply may power 1 card no issue but not both. Likewise 1 card may not produce enough heat to overheat but both cards might (especially if the rig doesnt have great air flow) The fans blowing full speed are an indication the cards are running hot fans not running full speed is actually a GOOD sign. The kill-a-watt should help us alot. It will tell us how much power the rig is using and if your running to close to your PSU’s limits. Also if you can see the power consumption as it reboots, that could tell us alot as well. If you have a 650W power supply thats using 600-650W continuous you are certain to see crashes. Id start with getting those power readouts and maybe jacking up the AC or setting up tons of large window type fans to try and cool the unit. Your bios/motherboard should have temp readings. If it doesnt you can get a seperate sensor. You can also try running your rig on windows, if anything ti will give you more t work with for troubleshooting. The fundamental problem with Toomim's company is that he is not aligned with his customers. He did not create a business that is win-win, but one where he is making a large profit while his customers are losing massively. Zeropond set a profit margin up front and promised to upgrade hashpower as much as possible during entirety of contract. Much better incentives. Very happy I choose them. Toomin, whether or not you can legally fuck your customers over is irrelevant. You don't get far in life by fucking over your customers. You should restructure all contracts such that your interests and incentives are aligned. So you are working for and with your customers, instead of against. Zeropond just increased their customers' hash rate 4x for both their genesis and Dec contracts solely based on adopting tech improvements that they did not develop.working with their customers and doing what is 'right' - no skin off their back and not being selfish about the increased gains. Conversely It's so easy for Toomim to just say 'a hash is hash.that's what I sold, blah blah' when all he is sayin is 'I'm a selfish prick that has no obligation to my customers apart from the contract regardless of the unknowns including the tech that I did not produce' It would be the 'right' thing to do to adopt the public miner and increase everyone's hash rate.but he's just a prick like that and has no sense of customer satisfaction even with his so called 2x avg voluntary increase! So we are stuck this prick oozing gonnorhea. I'm disgusted. It's generous of Zeropond (and Toomim for that matter) to increase their customers hashrate but it is still very difficult to judge whether that's only generous, or perhaps just about fair, or actually only a marginal loss to them. If cloud mining ops want to become more transparent and less of a risk investment towards their customers, especially on coins that don't have optimized mining algo's yet (!!!), it would be better to sell Joules (Watt-second) instead of hashes. By doing this, you eliminate most volatility of the coin and you make a deal in the most stable variable in this whole mining business and therefore the very existance of these cloud mining ops: electricity price. That is what these companies deal in: electricity. Of course there would still be variables like which hardware is used and which mining software, but these aren't volatile and moreover, verifiable by anyone. So, say that Toomim's 40sols/s miner had used 200J (no we could never verify this, but we also couldn't verify he could actually deliver 40H per 290, so that doesn't matter) and we had bought a 500J (or 100 sols/s) contract, how would that look today? I don't have all numbers handy, but let's assume the latest miner churns out 150 sols/s at about 250J. So with your 500J contract, you'd get 300sols/s, a threefold increase (note the numbers are just made up for the example). I'm not so involved with power usage at all, but there must be somebody around here who could could run a comparison between SA v1 (also around 40sols/s) and the latest miners for power usage. I wouldn't be surprised at if you would come near that 3-4 fold increase in sols/s per Joule. Twice seems very low to me, so I kind of wonder how much juice the Toominer pulled. This approach still doesn't solve any liability issues on service downtime, although it might be a bit easier to hide behind having put so much Joules into the GPUs and not taking responsibility for what comes out at the end. You can't calculate joules that easily, Claymores miner on earlier versions for example would hash better on older cards vs newer ones and it's currently doing better on newer (lower TDP) cards with headroom for more (IMHO). Total joules would depend on total system usage and maxing out the motherboard (7+GPUs per) with lower end cpus, cheap motherboards and running off a usb stick. Note: People calculate based on what the GPU is worth, not the infrastructure needed, additional components (CPU/MOBO/PSU/RAM/Disk space), electricity, downtime or man hours. While I dislike Toomim Bros stance, all participants knew exactly what they were going to get. I personally invested in various methods to mine ZEC but I knew the risk involved. 1) I got some Amazon AWS instance reserved for 1 year (they will never ROI) 2) I then invested in a Toomim Bro competitor (I most probably won't ROI on that either, unless I hodl the coins and sell later when I break even, if ever). 3) Invested in my own hardware and setup some Rigs (prior to launch). I also have a plan 4 (will wait for this one) 4) buy coins when miners are losing money on electricity. I would of been better off just waiting and buying rigs now, but that is the risk you take on speculating. For those wanting to profit off the increased price / slow start. Unless you had a private miner doing what Claymores miner is doing now and solo-mining with AWS instances (again with increased H/s miner) you wouldn't make much. This is coming from a person that has been active and testing all iterations of software and options to mine Zec from the first zcashd releases. Just My 0.5 Zec. As you are aware, we had some technical problems during launch. I promised to compensate our customers with at least 100% of the missed revenue, and said that I would give the specifics later. The time has come for the specifics. First, the overview: We will compensate you all with 20x the amount of ZEC that you would have received in the first 96 hours if everything had gone perfectly. Now, the details. • We promised that our hashrate would start on October 28th. Although our contracts did not specify a block number or a time, we are starting our compensation calculation at block 1. • For our auction customers, we said that we would deliver 3x the hashrate that our customers paid for. While this is not part of our contracts, we will still honor it. We are including that 3x multiplier in our compensation package for auction customers. • Due to the rapid block rates of the first 2 hours, orphan rates were significant, and would have caused a real miner's revenue to be less than the theoretical amount. For our calculation, we assumed an orphan rate of 0%. • We provided some bursts of hashrate to some of our customers on Oct 28th and on Oct 29th, and we provided between 50% and 500% of each customer's target hashrate on Oct 30th and Oct 31st. For our compensation calculation, we will ignore all hashrate that we actually delivered during the first 96 hours. Our customers will be compensated with 20x the amount of ZEC they would have earned in the first 96 hours in addition to whatever hashrate they actually received during that time. • We have been significantly overdelivering on hashrate since Oct 31st. Even with the downtime, our customers have received an average of 66% more hashes since Oct 28th than we said we would deliver. We are giving that extra hashrate to you for free, and our compensation package is in addition to that. • During the first day, several pools (especially Suprnova) had technical glitches and performance problems. Many were rejecting perfectly valid shares, either due to misconfiguration or due to DoS attacks or scaling issues. Our compensation calculation is based on what would have happened if the pools had all been working perfectly. • Several customers had entered in their pool information incorrectly, such as by omitting a worker name with Suprnova. We will compensate all of our customers as if they had working pool information as of block 1. I calculated that an ideal miner with 1 H/s would have earned a total of 0. ZEC in the first 96 hours that mining was possible. We will give our customers 20x that, or 0. ZEC for each 1 H/s that we promised. A customer who ordered 100 H/s from us should have earned about 0.177 ZEC during the first 96 hours; we will give them 3.54 ZEC. (We reserve the right to round up.) Note that as of block 10182 (current as of this message), an ideal miner with 1 H/s that was active since block 1 should have earned a total of 0. Even before our compensation package and with all the downtime, our actual customers have already earned more than that, typically around 0.0048 ZEC, due to our hashrate overdelivery. Our compensation package is in addition to that, which means that a 1 H/s miner will have received 0.2 ZEC once they get our compensation, or roughly 8.3x as much. If you wish to review my revenue estimates, you can find the source code. Compensation payments will be made within two weeks. We will collect Zcash addresses of customers via our website, on a page that we will build soon for the purpose. Do not send us Zcash addresses via email, as anyone can easily spoof an email address to steal a customer's payment. The two days of mostly-downtime on Zcash launch was by far the worst service outage we have had in our existence. We try to hold ourselves to a higher standard of service. That's why we're not just compensating our customers with 100% of the ZEC they would have earned. Even though we did not have a service level agreement in place, we still think we should overcompensate for any downtime. Given the prominence and severity of our launch problems, we felt that 10x was an appropriate overcompensation multiplier for this instance. Since we're already overdelivering at 2x, we decided to bump it up to 20x total. May the hashes be with you, Jonathan. It's also the SI unit for waste heat, which is the actual sense it's being used in here. The work accomplished here is measured in solutions or hashes, not in terms of how much we increase the average energy of the nearby molecules of air. The use of joues or watts as the unit of sale gives rise to. The cloud mining seller (me) should not be rewarded for being inefficient. The unit of sale should provide me with as much of an incentive to improve my efficiency as possible. That said, I enjoyed reading your comments. I guess in the end you are right, it was just a thought experiment. Hopefully people will now understand that when a GPU algo hasn't been touched by somebody like Claymore, there is a potential for dramatic improvement. And still this isn't always the case. The GPU miner shipped with the release of ETH was never improved much further than 10-15% tops ( private kernel) and it took about a year to get there. Looking at what is happening right now with Equihash, I support 's Cuckoo Cycle bounty fund even more. While it's fun for the devs to have an arms race like this, it's ruining alot of peoples investments. Then again, the profit has to come from somewhere.

Genesis Zcash Mining Since I have been mining with Genesis I have seen them doing everything they can do to help their customers. From advice to implementing new ways to help save money in transaction fees, we have all seen Genesis hard at work to make it better for everyone that is part of the best cloud mining group in the world. No matter if you are just starting or if you have been with them for a long time they see everyone as part of the team! No matter which crypto-currency you choose to mine they stand behind you 100% with your best interest in mind! Published on 6th January, 2018. Very pleased with the overall experience so far While it is too early to remark on the Monero contract in great detail - as I just purchased it, I am very satisfied with my early experience with Genesis Mining. My questions were addressed with informative and thoughtful responses. Cloud mining. High income from mining to 4% day, free 20 gh/s for registration. Btc, doge, ltc, and gh/s. 0 users purchased 0 gh/s 0 $ paid we work 69 days. The user experience is intuitive. I have already recommended Genesis Mining to friends and family members. Moreover, I have upped my investment as I feel that I am working with a team that values integrity. Published on 6th January, 2018. Houdini two year contract of genesis immediate profitability I am mining and trading bitcoins, Ethereum, litecoins on 3 continent (Asia, Europe, Middle East). But i always wanted a quiet back up with no maintenance tasks and no risks. For this reason I always add some cloud capacity at genesis. I have just bought the two year Houdini contract at genesis. I decided to buy more capacity at genesis because my previous eth investment repaid itself in less time that I thought. A couple of days after investing in the monero Houdini contract I receive promising daily payments and I already foresee that the investment will repay itself in a few months. Published on 25th December, 2017. The biggest and best crypto cloud miner. I had no idea what cloud mining was until I discovered your business on YouTube. Many of your very happy and satisfied customers chose to post videos describing the service you provide. I have since purchased a few contracts from you and look forward to using a currency that will not deprecate in value such as the one I am currently holding some savings in. Thank You Genesis Mining for giving myself and many others an opportunity to invest in this new industry. Firikyiwa published on 14th December, 2017. The miner´s littel helper it´s Stille way too early in the process to conclude anything; I expect to start seeing some results in the start of January 2018, do not expect the same level of monitoring and software set up or insight, that you have when mining on your hobby rig. I decided to go for the two-year Ethereum contract, one of the coins I also mine my self and a crypto-coin That has done well for me. My estimate for ROI at the end of the contract is 160%. But let´s see how it has done by November 2019 Thomas S. Published on 27th November, 2017. LTC After monitoring my contract on 50 MH/s on Script, my payout on Litecoin is 3.6825. With current price of $26.97/LTC, my mining payout per 30 days is around $119. My rate of recovery on investment is about 7 months as compared to many other pools offering around 10 to 11 months. It's.pretty easy to see the efficiency & advantage offered by Genesis Mining. The Genesis Team is really doing a good job; might see you folks when traveling for Northern Lights! [email protected] published on 21st May, 2017. Not bad but needs improvment. I think the whole sign up process could be improved and made even easier.Think of your older and not so Tec savy customers. They are the ones with some money. It's not easy to find your progress, you have to dig for it. It's not easy to log out you have to dig for that to. I would physically like to see my costumizable personal miner at work if I want to. In a graphic way of course. The contract I bought was not clearly labeled for two years. I'm doing my mining from a phone app and I'm not very good with it but I did get through the process so I give your team a thumbs up. Paul.coenen9 published on 6th May, 2017.

Development ethOS was released in February of 2016. All proceeds from ethOS sales are distributed among the development team. This is cool, but they should not offer a C corp as the default choice. An LLC should be the default for the vast majority of entrepreneurs. The only reason VC-funded companies are C corps is becaused VC LPs don't want to be hit with taxable income (which would flow through the VC to them). An LLC is much better for a variety of reasons: - Flow through taxation = you only get taxed once. With a C corp you pay corporate income tax and then you get taxed on any distribution - If you sell the business, you better hope you have enough leverage to get a stock sale and not an asset sale, because in an asset sale, you're again getting majorly double taxed. The vast majority of exits are asset sales though because they shield the purchaser from unknown liabilities - From an LLC, you can easily become a C corp. From a C corp, it's majorly difficult (practically infeasible) to become an LLC; you retain optionality in one case but not the other. “Real estate is about the income stream,” explained Barrett. “ Investing in places where people want to live or work.” So, if the clients and tenants see.

The Ethereum BlockChain Explorer, API and Analytics Platform.Missing. While I don't have much to add, this is very interesting and almost feels patriotic (as an American.) Stripe is, in a way, hacking the global economy and luring entrepreneurs to the do business in the United States. While this iteration may fall short of perfection, or open questions, it also opens up some imagination and interesting ideas or possibilities. Could this be the beginning of startups offering citizens of one country, the ability to (easily) incorporate / operate a business from any nation? Perhaps this is more interesting when considering crypto-currencies which are already eroding national boundaries in some sense. While I cannot say this is a good or bad thing, it is interesting to think about the consequences and evolution of this concept plus crypto. To me, the idea of operating a business (pseudo-person or entity) in any nation, is intriguing. Especially mixing in the possibilities of Ethereum, Blockchains. Imagination running wild right now. This means nothing for me (and should also mean nothing for the targeted audience of the post). I've been constantly ignored from Stripe since they launched their beta in Mexico (actually way before that, I subscribed years before, when Stripe launched in the US). I can't do business with them because I'm not part of their secret club, while at the same many businesses here somehow get access and start using them. That feels like some kind of unfair competition. I know, you are going to say, they are not obliged to provide service with you, but then, after reading the kind of PR they publish (like this one) you would feel like it, at least they should be morally obliged to stand by their word. 'Stripe Atlas is invite-only to start. You can apply directly or get a referral from one of our partners.' Oh ok, so another secret club, and this time the gatekeepers in Mexico are some guys named Antoni and Lelo de Larrea, which for you outside of Mexico, the Larrea family are a powerful group in Mexico that came to be through corruption, government favors and pretty much all the things you usually hate from Mexico. Remember when the miners in Chile were trapped and then rescued? The same thing happened at more or less the same time in Mexico, a lot of media coverage here in Mexico, the mining company owned by them, it was relatively cheap to rescue them but they decided not to do it, they let them die because it was not worth the money. And now I have to do business with those people if I want to process my payments? Yeah, thanks Stripe, but no thanks. I just checked the prohibited businesses I am fine with most of them being prohibited but at some points it's getting quite restricted: 1. Virtual currency that can be monetized, re-sold or converted to physical or digital products or services or otherwise exit the virtual world 4. Sexually-oriented or pornographic products or services 9. Engaging in deceptive marketing practices (here: who decides what is 'deceptive') 14. Age verification 15. Age restricted products or services (which are the most products/services) 50. Centralized travel reservation services or travel clubs. This is huge. As someone who is involved in the digital nomad community here in Chiang Mai, Thailand - getting incorporation and processing set up for a lot of people here is very difficult. Although places like Thailand are a great place for independent bootstrapping and theres a solid network of entrepreneurs - one of the biggest hurdles is incorporation, banking and acquiring. This is taken for granted when youre living in a first world country - but for the new location independent entrepreneur who is building their startup from cafes or coworking spaces in Chiang Mai to Ho Chi Minh or Medellin, getting a corporation, processing and a bank account structured is often a huge problem. Perhaps the least talked about hidden danger with this service is the fact that by establishing a US nexus, you're putting yourself in the crosshairs of patent trolls. Software patents pretty much aren't a thing in the rest of the world, and you can happily trade from abroad with US customers without patent trolls trying to shake you down. That and the vague potential for national security letters should you have possibly interesting information. It's all a balance of risk though and for a lot of people the benefits will outweigh these risks. For a lot of people these risks will never materialize. A very nice product it seems. But people should be aware that having a US business, bank account and so on makes you a 'US person' in the eyes of the US government which comes with downsides. If you recently tried to open a bank account somewhere you might have seen the form you have to fill out which tries to discover if you are indeed such a 'US person'. I don't know exactly what the result apart from probably the bank refusing to take you as a customer is since I am careful to not become such a 'US person'. Nowerdays it's becoming increasingly a better idea to incorporate in a different country than the US if you can, especially for online businesses including privacy, tax and ease of doing business. This solve so many problems that our startup (www.worldpackers.com in Brazil) have! We are a global marketplace, so we have to charge people from everywhere, and stripe still doesn't cover Brazil. Opening a Delaware company is a must have as we are starting a series A fundraising. And the network, wow! I wonder how achievable is the direct application as a way for getting in the beta. We are not part of any accelerator by choice (except YC that rejected us on the interview phase). We have a great company, just not important friends. So, a question to the community: What is the better aproach: Direct application or look for someone to refer us? Interesting angle. For a while I've wondered why nobody does a tech/startup version of 'Company in a box'. This looks like it's exactly that. Incorporation, payment processing, the works. Is Stripe getting a cut of the eventual revenue from the service providers that are providing the offerings? What's the incentive on their side? Or are they just hoping to scrape by on the transaction fee revenue (which are way less than people think they are because they pay out most of it upstream[1]). Also, what's the expiration on the $15K of AWS credits? The usual one year or longer? [1]: If you're wondering why just think about how you get ' 1% cash back on all purchases!' While I really like the ideaa one stop-shop company creator I am a bit unsure if Stripe will achieve the same quality level like dedicated registries which do this for several years. Points I am missing/not seeing: - Can I decide about the administration location (eg also Delaware or does it have to be my actual location)? - Can I get some virtual office with address, mail forwarding, etc, sometimes offered by registry? - Is Stripe a full state approved registry or do they use 3rd party registries? What are the ongoing costs (there can be significant differences)? - How many people are in customer support? - Is Stripe stated as the registrant in the Delaware corp database? The only advantage I've seen is that Stripe is opening the bank account for you and it seems you do not have to visit the States but other than that I am not sure if going all-in with one entity (Stripe) is a bit too risky. And if looking at dedicated registries there 3-5x more information on their websitesthis is not a clear indicator for quality of service but since this is not Stripe's core competency it's something I'd be a bit cautious. But still something Atlas can catch-up. I absolutely love this idea - it solves for a HUGE pain point that entrepreneurs have dealing with the logistical, legal, and financial groundwork for a startup and getting to payments easily. Good lord, if Atlas were around for me to setup my startup, I would be crying tears of joy. What I'm confused about is why they didn't focus more on the convenience advantages and positioned Atlas as a non-geo tied incorporation/setup offer. As many people have noted, the advantages of doing business as a U.S. Company if you're not in the U.S. It seems far more appropriate as a side note to the much needed advantages of solving a legal, financial, and accounting nightmare just to get payments. Why emphasize international? We have already incorporated and has been a long and painfull process, but not as painfull as trying to open an account at Silicon Valley Bank. After some back and forth, they rejected our application saying: Ive just received your info from client support and my apologies if no one replied to you sooner. Unfortunately we wont be an appropriate banking fit as we dont typically bank service providers. We maintain a focus on venture backed companies and typically teams that are local to our presence (based in Silicon Valley, SF Bay Area, NYC, Boston, London).Just signed up for the beta, pretty excited about this! > - Pay federal income tax on income generated in the U.S. > We strongly recommend that you work with tax and legal experts to handle these ongoing requirements. To help, Atlas users get direct access to resources and guidance from Orrick and PwC. You can also chat over the phone for free with a professional from PwC. ^ from the FAQ, should be in bold characters on the home page. 'tax on income generated in the U.S.' , what does income generated in the U.S. Good luck finding an easy answer to this which will satisfy both your local jurisdiction and the U.S. PwC and the likes thrive because the tax code is a complicated beast that just get bigger every year. Apart from raising money in the US, as a Canadian company, I don't see any advantage to this. The amount of knowledge needed to deal with those issues clearly makes it suited to experienced entrepreneurs with the means to get good counselling. My guess, it's designed for YC founders.:). While Stripe team is great and it's always good to place all services under one roof, both registering US corporation and opening US bank account online is not something new, Harvard Business Services (www.delawareinc.com) had done company formation for years for startups and the fee is nicer ($250 single payment + $50/year for registered agent vs Atlas $500 single payment + $125/year for registered agent). Atlas is twice more expensive, which may be sensitive for early-stage startups. We formed a C-corp with HBS. Then opened SVB account for free, printed standard incorporation docs, got EIN from IRS and opened account with Braintree (could be Stripe as well), all for free. We just had to use different websites instead of one, but no additional difficulties. Does this mean Stripe will phase out the ability for Canadians to accept USD and deposit funds directly to Canadian banks offering 'US fund' accounts (that are not technically US bank accounts)? Currently, a Canadian business can accept $USD with Stripe and have it deposited directly into a Canadian US fund account without conversion to CAD. Stripes competitors can't do this - and have traditionally told Canadian businesses that they would have to incorporate in the US, setup a USD bank account at a US institution, in order to accept USD without conversion back to CAD. That process is what Stripe Atlas simplifies. PayPal allows Canadians to accept USD by holding the funds in a USD PayPal account. However, getting the funds to a Canadian bank account always involves converting to CAD. I might face the decision of incorporating soonish. My current plan was to just incorporate in my country of residency (Germany) as that's the easiest route. How hard is it to migrate an existing company to Dalaware-C (D-C) which seems to be the gold standard for venture backed startups? Or is the recommended way just becoming a D-C from the getgo? I'll gladly take tax cliff notes on being incorporated in the US as a non-US citizen starting a business.Basically if it doesn't screw me tax wise I wouldn't mind incorporating as a D-C from the getgo. US taxation seems a bit scary and I don't think it's all that easy to research. Would love some advice from Germans/people not living in the US that are incorporated in the US. Between the recent 'legal papers' post from YC and this it seems like it's never been easier to do the non customer facing stuff of a startup. Very good as this is something I'd worry about way too much. They aim to help global community of entrepreneurs but it is tailored for the specific silicon-valley community. - c-corp only - investors in the valley work with it mostly. Even though for MOST of the businesses s-corp or LLC will be better. - silicon valley bank - is very popular in the valley, but has limited support if you're outside as opposed to more popular banks. (transfer fees, integrations with other providers like payroll etc) i like the idea, but they have to think outside of their valley scope to really help people worldwide. I always wonder with things like this, when will we be able (with an online business) to essentially say that your business has no fixed abode, and therefore you won't be paying any country any tax. If everyone was using bitcoin or some other anonymous currency it would be pretty straightforward assuming that was how you took payments. Your only trouble would be remitting money into your own tax jurisdiction - but then you may not have one of those either, assuming your were floating about the world. Few Nice Words about Stripe before the 'But' ------------------------------------------------ The Stripe team straddle technology, trust and finance at scale. I have seen almost every interview PC has done and the insights the guy brings up are super interesting and he is a lot more measured than most people, and it seems to be true that he is also a lot more correct. Super smart team, super smart vision, seem to have great integrity and provide opportunity to many people. This focus on 'building roads while everyone else is building cars' has been really mutually beneficial to the ecosystem. The 'But' -------------------- To reflect breifly on how Stripe frames itself, their data points, and just the general caliber of the people there lead me to believe this is the best way to solve global commerce. I suspect they have given it quite a bit of thought, and the move seems to be unite all of the things in one place. In the narrative analogy, what about electric vehicles? On one hand, alternative currency and technology companies have the luxury of, they themselves, being an infrastructure to allow for distributed global commerce, a new framework for growth, and the natural rise of the global internet company unbound by arbitrary lines drawn when imperialist did the carve out of the world. On the other hand, I would have loved to see a structure to derisk, a company and allow them to trade internationally with some semblance of compliance and also speed a structure where a company registers a business as the domain. Stripe assuredly knows that Ethereum, BTC and Blockchain are super important, and in many ways, solve the problem Stripe sent out to fix. Possibly with a better framework. I think the Atlas program is great, a net good, and a phenomenal way to solve what(as a US citizen I luckily haven't been subjected to) is a huge painpoint of just selling into America, trying to work in America, and the regulatory complexity of that shitshow. I am a bit bummed because Stripe is often correct, and while I suspect to some extent it is tough to de-risk this, they just see the timeline being much longer than I do. They're probably right, I am looking at it at the 'S' bend of technology adoption, and they are looking at it from a corporate standpoint. Just sucks that centralizing all of these new companies into the USA ends up being the best way. I have to hand it to the Stripe guys/gals, this was such a feat of complex coordination that it is absolutely staggering they were able to manage several verticals of beurocratic inertia in parallel like this. I work in fintech where one of the guys in the accelerator I was talking to today was explaining how we might need a quick restructure of a few assumptions, he explained his implementation like this: The API ends up literally being a call. You call a human for credit appraisal, the backend has the data and his system has a rest API for fetching and pushing data, and still a human reads the huge red text: 'please copy and paste from [othersystem name] & hit enter', then his system generates all the regulatory compliance stuff and all the actually useful stuff needed, but a human is in the loop because it is too complicated for the internal dev team to allow (or to post) the fucking data. * Sales team loves this process innovation. * Friend responded (as I am assuming everyone is thinking) that it is NOT regulatory hurdle, purely tech. * You have heard of this bank. So kudos to Stripe, awesome job, complexity is immense and I am sure this could be life changing for many. I would still love to see them embrace something like Ethereum near-term, but congrats. Given that Xamarin bought RoboVM last year and that the project went closed source and raised prices just after that, it's fair to assume that RoboVM is dead. Also, I'm personally not happy about this. I think people on HN should know better. Besides a couple of black swans being the exceptions that confirm the rule, acquisitions is how projects die. This is because acquisitions are either defensive or acquihires. And even when done out of a genuine desire for progress, big companies end up choking these acquisitions to death, after all they weren't capable of such progress in-house, with the project members moving on after one or two years when their contract expires. But hey, people were excited about Nokia as well. I know it's undisclosed but it would be very interesting. Hopefully someone leaks it. The rumor was Miguel told MS to 'F*#K Off' when MS presented him with an offer many years ago. This lead to CoreCLR being open sourced and Visual Studio Code being built. I'd like to know if by undermining parts of Xamarins business they were able to get them at substantial discount - especially with the tech industry downturn. Or if failure in the Windows Phone market has made MS desperate and forced their hand. Given it's undisclosed I'm guessing it's the former. I'd like to know if telling MS to 'F#&K Off' was a good strategy:). .NET now needs a solid compile-to-browser story - which is presumably coming with some future version of web assembly (initial version doesn't support GC or threads) I'm looking forward to the day where I can ditch C++ for portability -.NET really is an ideal replacement for most apps - you can write apps that don't stress the GC by using value types and can control memory layouts relatively well (unlike Java) and at the same time you can use reflection, GC and all the niceties of modern programming platforms - unlike C++. As a Xamarin subscriber, I'm guessing the future success of the merger (and product future) depends on: 1) addressing the price-point,2) core clr integration,3) retaining the top engineering talent at Xamarin,4) addressing the iOS designer-specific issues A couple notes: For most LOB apps, I'm not convinced the code re-use is significant. The bulk of work is in the interface and navigation which is, necessarily, handled by coding android / ios specifics. Despite noble effort, the iOS design essentially needs to be done in xcode (point 4 above). The build/release process is and (presumably) always will be locked behind the gates of technology's North Korea (Apple). They can throw a switch and restrict 3rd party runtimes if and when they choose. For businesses in the 5-100 million range, writing an expense app in 2017, MSDN Xamarin should be a logical choice - but it has to be a platform with the reliability of.NET and a simple cross-platform designer. For app-centric startups, games, POS systems, etc. - it's probably a bad move. For msft devs (and we are aging) it's win-win. The lure of C# gets you into mobile dev, and you will learn iOS and Android in the process.

If you are into Crypto Currencies, you should be familiar with the name Litecoin as this coin has been existing since 2011 and one of the very first true “altcoins” that has stayed. There are a lot of altcoins that tried to compete with big names but didn’t have enough gas to last that long. Litecoin, on the other hand, has been there for a very long time and is just showing how resilient it can become when it comes to market volatility. And with the recent announcement of leaving Coinbase to focus on his creation, is good news to the Litecoin community! Litecoin just recently past the after many years existing in the market. This simply cements the idea that the coin is legit. And when it comes to crypto currency mining, you, of course, need to make sure that the coin that you are mining is worth something to avoid converting it to Bitcoin or holding on to something that may be worth nothing after a few months. Before deciding on to mine Litecoin, you can actually calculate how much you would make through this. Why Mine Litecoin? There are a few things why a mining rush starts. First, mining rush comes when people see an opportunity to mine something that is already valuable or they see something that can be profitable after a few years. Due to the recent revival of, this would attract people to start mining Litecoin now. This would be the perfect time to do so as the creator of the coin now plans to divert his full attention to the project that has been going on for five years now. We are all quite aware that when a coin goes up suddenly, there is an expected dip a few days after that sudden increase. Compared to Litecoin’s cousins, the crypto currency market has always been crazy on the charts throughout the years. Litecoin has been steadily existing under the radar and of course still working until this day. With that being said, which mining method is perfect for mining Litecoin? You can, of course, use your GPU to mine crypto currencies. But a GPU miner is easily defeated by new ASICs that come to the table. Since has been available for Litecoin for a very long time now, it would be better to go this way. But of course, we have cloud mining for you to forget about what type of hardware is perfect to mine Litcoins and just pay for a and you are good to go. Please keep in mind that when it comes to cloud mining contracts, you need to read through each company’s policies. One thing you also need to keep in mind would be Litecoins mining difficulty which can be viewed through. The more miners that jump into the opportunity to mine Litecoin the harder it gets. That’s why a crypto currency’s difficulty constantly goes up, this should be one of your points to keep in mind if you want to earn in cloud mining. Best Litecoin Cloud Mining Websites Here are the websites that cater cloud mining for Litecoin. Again, always read through the company’s background before investing money into them.

Here is a quick list of the latest CPU and GPU miners available for mining the Zcash (ZEC) that uses the Equihash algorithm used by the coin. Since most pools and miners are based on Stratum mining support you should be able to use them on almost all mining pools with support for ZEC. What you should be looking for is what works best on your hardware in terms of stability and what provides you with the optimal hashrate in order for you to maximize your profit. CPU mining is still viable as GPU miners are yet to be further optimized to be able to provide significantly higher hashrates, though you should know that the days of the CPU mining of ZEC are probably numbered. Because of the that Zcash has implemented the block reward is still growing, so even with price going down and the total network hashrate going up the overall profit for mining and selling Zcash remains pretty stable and most importantly pretty high compared to other crypto coins at the moment. Because of that it is a wise decision to mine and sell Zcash at the moment until the end of the slow start of mining when the block reward will stabilize at the maximum level of 12.5 ZEC and that should provide a more stable price per coin than at the moment. Mining ZEC coins now and keeping the coins may result in them loosing significant value at least in short term, though in long term it might still be a viable option, so consider what to do carefully. Best CPU miners for Zcash: – (also supports CUDA and OpenCL)* Best AMD OpenCL miners for Zcash: – Best Nvidia CUDA miners for Zcash: – (also supports CPU and OpenCL)* * The nheqminer is available with hardcoded pools from nicehash, suprnova and other mining pools supporting Zcash, so make sure you download the correct version for the pool you are going to be mining. Genoil’s latest ZECMiner is pretty much the fastest public OpenCL miner (Windows binaries only) for Zcash at the moment, though there are some stability issues with cards dropping to 0 Sol/s and the miner crashing. The situation improves with each new version, but the miner is still not that good stability wise. The latest Nheqminer supports OpenCL mining, but is slower than ZECMiner, even though stability wise it is better it is much better for CPU and CUDA mining though. Hopefully soon there will be other faster GPU miners that will offer more stability and features along the improved mining speeds, but for now you will need to do with what is currently available.

Bspus I´m mining to nicehash selling my CPU power, I just discovered that the best way is to download the oficial miner and then run it, it will run the benchmark and you can start mining zcash with it there is a option to see how is your progress go to nicehash site, then getting started, download the very left side software, install, run and you´l see for yourself. Or you go to the nicehash, go to the miner/seller drop down then my miner option then input the btc address you´re using and voila you will get a very nice web interface with your current results. To add when i try to add a pool and or worker on the nicehash site it wants me to enter in the details of a server and i mean i dont get that. Why doesnt it just provide me with me and then allow me to type my worker and then press add and then its done, why the bloody pain. Anyways, i then went ahead and entered in a (what i thought was a valid pool server as per a website i used which was pertaining to zhash or equihas, and then it told me it is invalid) i dont understand why it just doesnt give a list of servers, which i did actually see on another page there but the thing is it wants me to set up the worker and i need to do all that pain. I am taking steps backwards here, i dont know what i am doing. Copyright ©2014-2018 - - All About BTC, LTC, ETH mining as well as other alternative crypto currencies.

How can you use a rental property calculator to buy the best. (LTC) Ethereum (ETH) But out of them Bitcoin began to gain. What are Bitcoin Cloud Mining. Cloud Mining on Apologies for the delayed update everyone. Last I checked, has been back to their daily payout schedule. Currently, I’m mining Dash, Bitcoins and Ether. All other alt coins’ mining power has been utilised to mine Bitcoins. Genesis Mining Allocation I cry every night on the missed opportunity when Bitcoins were selling at the $3,300 to $3,500 range. As most of you would know, it is at $6,000 now. That being said, mining it has been reaping my huge returns. Return on Investment (ROI) Before you get all excited, the returns are not 100% from mining, a portion of it is mined personally by yours truly. I make use of the hardware from my office and just let the program run in the background. My daily estimated earnings hover around the $1 per hour range. It’s a slow climb. Dash Mining Contracts – ROI 86.5% I started investing in Dash contracts which cost USD93.20. 3 months later today, my Dash mining ROI has dropped to 86.5% p.a. I’d attribute the drop in ROI to the fall in Dash prices. Mining profitability calculator? The calculations of your cloud mining profitability are based on last 10 days performance (rolling frame). If you want to invest in bitcoin mining without the hassle of managing your own hardware, simply head into the cloud to earn your coins. Still, 86.5% in returns is still very, very substantial. Bitcoin Mining Contracts Ok, so I’ve messed up with Bitcoins here. It’s getting difficult for me to track what portion of my returns are from open-ended Bitcoin mining contracts and which are from my own personal mining. But the returns are definitely HUGE because of Bitcoin’s increase in value. I estimate that about 30% of the Bitcoins in my portfolio are mined personally. NiceHash Miner The program I use to mine personally is called NiceHash. It is free to use and eats up your PC’s GPU which in turn consumes your electricity. The interface is very user-friendly and if you’ve got a spare PC lying around at home, play around with it. But be aware of the spike in your TNB bill ( Disclosure – I own TNB shares XD). So there you have it, between my mining contracts and personal mining skills, I’ve more than paid for my initial investment in Dash contracts. It’ll be pure profits from here on out. Although at my company’s expense in electricity. If you’re planning to purchase mining contracts on, please go ahead and key in the following code: KT7r1S which gives you a 3% discount on your purchase.

Return on Investment It is important to note there are a lot of factors influencing the return of investment for ether contracts. The biggest 2 factors are ether price and network difficulty. Regarding ether price, ether is a crytocurrency and prone to high degrees of volatility. The price of ether may increase or decrease over the 2 year mining contract. Genesis-mining will deposit Ethereum to your designated wallet everyday for 2 years. It is up to you when you choose to sell your Ether. We can have a rough estimate of the amount of ether to be received using the (see note 2): Ether 100 Mhs Profitability We can see at the end of a year of mining, we would expect to receive a total of 85.45 ether (roughly 1781 USD of value, assuming 1 ETH = 20.85 USD). Assuming the above, for a full 2 year contract the yield would be 171 ETH. This would give a yield of $3570 for a purchase cost of $2715 USD (Assuming you use the 3% off coupon code “6bXKwD”). This would give you a 130% return on investment. However, before you get too excited there are other factors that will reduce / increase the ROI. First off all, if the price of ether drops, then the yield will increase. In fact if Ether drops below $15, the contract will make a loss. Network difficulty Network difficulty directly affects the return of investment. As more people mine Ether, the same reward is split between more users, resulting in less money per user (or hash rate). This means in the above calculation, 171 ETH would be MAX amount of ether yield. Most likely technology will improve and more miners will get involved, making it less profitable to mine. Where to buy Ether cloud mining currently has ether mining contracts on sale. Remember to use the Promotion code “ 6bXKwD” to get a 3% off discount coupon!! • 10 Mh/s was $358 USD for 1 year, now its 300 USD for 2 years! • You should always fetch the latest mining data directly as it incorporates current network difficulty. Assume electricity to be zero as genesis mining does not charge addition fees during the 2 year contract. Estimated Expected Cryptocurrency Earnings The estimated expected cryptocurrency earnings are based on a statistical calculation using the values entered and do not account for difficulty and exchange rate fluctuations, stale/reject/orphan rates, and a pool's efficiency. If you are mining using a pool, the estimated expected cryptocurrency earnings can vary greatly depending on the pool's efficiency, stale/reject/orphan rate, and fees. If you are mining solo, the estimated expected cryptocurrency earnings can vary greatly depending on your luck and stale/reject/orphan rate.

Contents • • • • • • • • • • • • • • • Introduction Mining is the process of adding transaction records to Bitcoin's public ledger of past transactions (and a ' is a colloquial metaphor for a single computer system that performs the necessary computations for 'mining'). This ledger of past transactions is called the as it is a chain of. The block chain serves to transactions to the rest of the network as having taken place. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual must contain a to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a 'subsidy' of newly created coins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system. This site will help you to compare all kind of hardware device for mining. XMR-STAK-AMD (2 THR, 2016/1600 Intensity. Soft PP table. SHA-256: 0000. Want to buy mining bitcoin hardware or ethereum mining graphics cards or GPU. And ethereum cloud mining contracts Prices are updated. Mining Contract SHA-256. Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground. Difficulty The Computationally-Difficult Problem Mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a is incremented. See for more information. The Difficulty Metric The is the measure of how difficult it is to find a new block compared to the easiest it can ever be. The rate is recalculated every 2,016 blocks to a value such that the previous 2,016 blocks would have been generated in exactly one fortnight (two weeks) had everyone been mining at this difficulty. This is expected yield, on average, one block every ten minutes. As more miners join, the rate of block creation increases. As the rate of block generation increases, the difficulty rises to compensate, which has a balancing of effect due to reducing the rate of block-creation. Any blocks released by malicious miners that do not meet the required will simply be rejected by the other participants in the network. Reward When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 12.5 bitcoins; this value will halve every 210,000 blocks. Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income. The mining ecosystem Hardware. FPGA Module Users have used various types of hardware over time to mine blocks. Hardware specifications and performance statistics are detailed on the page. CPU Mining Early Bitcoin client versions allowed users to use their CPUs to mine. The advent of GPU mining made CPU mining financially unwise as the hashrate of the network grew to such a degree that the amount of bitcoins produced by CPU mining became lower than the cost of power to operate a CPU. The option was therefore removed from the core Bitcoin client's user interface. GPU Mining GPU Mining is drastically faster and more efficient than CPU mining. See the main article:. A variety of popular have been documented. FPGA Mining FPGA mining is a very efficient and fast way to mine, comparable to GPU mining and drastically outperforming CPU mining. FPGAs typically consume very small amounts of power with relatively high hash ratings, making them more viable and efficient than GPU mining. See for FPGA hardware specifications and statistics. ASIC Mining An application-specific integrated circuit, or ASIC, is a microchip designed and manufactured for a very specific purpose. ASICs designed for Bitcoin mining were first released in 2013. For the amount of power they consume, they are vastly faster than all previous technologies and already have made GPU mining financially unwise in some countries and setups. Mining services (Cloud mining) provide mining services with performance specified by contract, often referred to as a 'Mining Contract.' They may, for example, rent out a specific level of mining capacity for a set price at a specific duration. Pools As more and more miners competed for the limited supply of blocks, individuals found that they were working for months without finding a block and receiving any reward for their mining efforts. This made mining something of a gamble. To address the variance in their income miners started organizing themselves into so that they could share rewards more evenly. History Bitcoin's public ledger (the 'block chain') was started on January 3rd, 2009 at 18:15 UTC presumably. The first block is known as the. The first transaction recorded in the first block was a single transaction paying the reward of 50 new bitcoins to its creator. See Also • • • • by David Perry • •.
