Rolf September 13, Check out the section below for how to keep the room cool. Mining going into too bitcoin detail, you bitcoin get all the nitty gritty right here: Im in Phoenix area as well. They are a little behind on their mining, but if you buy from them Software find they ship to you. To ensure you have every libraries installed I strongly software you to recompile the miner you need, Minera has a utility script to do this, please look below. Let me know my good sir.

Why do you say that it is no longer possible? Patrick January 12, 6: Does this change the calculation at all regarding the amp draw? Ken November 27, 2: It turns out they are more trouble than they are worth.

Looks like the following: But you software try it and see if it works for you:. Kraken - The largest European exchange with same-day SEPA Local Bitcoins - This fantastic service allows you to search for people in your community willing to software bitcoins to you directly. There are a couple things you want to think about for cooling the Bitcoin mining facility in Phoenix. Intel Core i Sandy Bridge bitcoin. Please correct my understanding. In my scenario, I originally mining had about 20 Mining, and I needed bitcoin power 3 Machines.
Under the co-operative format users could host their equipment by buying tokens similar to the Gigawatt ICO except this would be entirely a member-owned and governed entity. The entity would also function like REI as a consumer co-op so that we make money through hardware sales to the general public with members receiving dividends based on their purchases.
The mining entity would not generate profit and would exist based on token purchases that function as member capital investment. The goal is to help decentralize mining and reduce the transaction costs and learning curve for small miners through a co-op entity that helps streamline the process for everyone and brings more overall efficiency to the network.
Rolf September 8, 4: When I lived in Colorado I would drive all over Wyoming for business. I remember the drive from Cheyenne to Casper, and seeing the huge power plant just southeast of Casper, and thinking it would be a great place for mining. I still have friends there, and would love to visit. I am a fan of starting small and growing over time, though, and am too busy for anything else, so this is not something I am interested in.
Mark November 22, 8: Mike November 27, James Coberly January 15, 4: We run facilities in WY specifically built for miners. What space are you looking for? Terry September 3, 2: My question is about the PDU. Do i get a bunch of socket PDUs?? Ken September 3, 7: Your pdu will normally have a current limit per outlet.
Nick September 8, I am curious on what you would recommend for a power supply? I am trying to run large power supplies so I dont need to run as many. Parallel Miner has some good ones.
Nick September 9, Do you think its a bad time to invest in a setup? When are we to expect new bitcoin mining hardware? From what I read on Canaans website will have new hardware.
Does anyone know a more accurate release time? Kelvin September 10, 8: If Bitcoin prices were to decline significantly you would have effectively a total loss and if a new unit arrives with a higher hash rate then you would effectively have a sunk cost in depreciation that is unrecoverable and possibly will never be recovered from the diminishing positive return from your mining.
In general, you want to mine with the fastest available hardware that gives you the fastest ROI break even on your hardware costs. The size of your initial investment should not be your main concern rather the speed in which you can ROI break even should be. From the sound of it you are purchasing new Avalons and again, comparatively speaking, that is a terrible investment unless you have a source of free or extremely cheap electricity.
And even then I think it would be a colossal waste to be consuming electricity even if it is renewable like that to generate a return that is comparatively lower than most of your other options. Currently GPU mining for Ethereum or Monero are nowhere near the ROI rate that you can get with ASICs but my feeling is that Monero has the highest potential price increase in the near term and is probably a good coin to mine in general due to their very stable developer community and positioning as a high utility crypto i.
And you can build a reasonably priced XMR miner with a variety of different hardware. Todd September 10, 8: Great feedback Kelvin including your feedback on my posts as well. Points my nose in a direction to dig deeper and learn much more. Eclipse December 12, 3: Todd September 9, Great article and website Rolf.
My question is about acquiring S9s. Approximately what price should I expect to pay? It seems they are also though to come by. What sort of lead time did you face before receiving your rigs?
Kelvin September 10, 7: No S9s have been announced since late July or early August and those had a ship date of mid to late October.
Todd September 10, 1: You mentioned that with an Ant-miner S9 one should be able to generate about 0. Please correct my understanding. What am I missing? It is all dependent on the network difficulty rate which is basically to say the more miners there are online the more the price has to increase to keep the return up.
Then you need to take into account the reward halving that occurs every 4 years. Look these things up as they are readily discoverable on the internet since they are intrinsic to what is Bitcoin. Wikipedia may give you all of these insights. If the price crashes, you may find miners going off line, which actually causes a kind of negative feedback loop as transaction times increase as panic selling i. Nick September 11, 3: Thank you for you knowledge and insight.
However this is my situation. My basement is relativly cold all year about 10 degrees celcius. I am looking into getting amps of volt service installed. I would like to diversify in my crytos that I mine and am considering 15 antminer S9s watts 15 Antminer D3s watts 15 Antminer L3s watts. What do you think of this model? Ken T September 11, 3: Just a comment on your power calculations. If you have watts of power at 3 phase, you need to divide by 1. Youre actually pulling A of draw not Dont forget to plan for HVAc.
Rolf September 11, 3: I think it is diverse enough. I also think you are going to overheat your basement in a hurry. You will be putting 50KW of heat into a small space. I would not do this without less than 15, Cubic Feet per minute of ventilation. Nick September 11, However I did find a nice warehouse with plenty of space and amp 3 phase v. My next question is I am not having any luck with bit main its been almost a week since I sent them a ticket about a purchase order.
Does anyone know what kinda timeline bitmain is taking for responces? I could Imagine it is insanely busy around there with all the craze of mining cryptos. Ken September 12, 1: If you asked them about a new PO for purchasing miners, forget it they will ignore you.
The orders for new miners happen every few weeks and the website gets slammed with traffic. Thanks for jumping in an answering questions that people have.
I agree with every one of your answers and comments! Mark November 21, 6: Ken November 21, 7: If you use 2 of the v lines you will get v. Thank you so much for the quick reply. If those machines can handle V, 3 phase power, that would be 8 machines per strip.
Thanks again for the help. Ken November 22, 2: Remember in your calcs that a 30a circuit will only deliver 24a through the pdu. Mark November 22, 2: Do you mean 3 phase or single phase.
Ken November 22, 4: Three phase would have four wires, your pdu plugged into a 30a circuit will only have 3, 2 hots and a neutral. When you have a 3 phase supply most loads will draw off of only two of the phases which is how you get v out of two v lines. Short answer — a three phase supply broken out into v circuits will drive an antminer psu just fine. Mark November 22, 5: Ken November 23, 8: Im sure Rolf may chime in with additional insight but for now, I think I understand the gap here… You will -not- be delivering true 3 phase to an antminer power supply.
You will be delivering single phase. No ATX power supplies that Ive ever seen can accommodate an actual 3 phase supply Y they accommodate single phase supplies and prefer them to be above v either or The efficiency people refer to when discussing 3p is related to the cost of getting service and how many devices miners can be run off of a given service size.
For example a a v service wont power nearly as many miners as a a Y service. Hope this still helps, and Ill drop off of the responses if this still doesnt get there and let someone else give it a shot. Craig September 10, 5: What pool did you say you were using?
I heard like apc. How did you choose that one? How often does it get a coin on that network? What site are you buying your asic miners from? And a lot want pay bitcoin; how do you protect yourself if they never ship? Nick September 12, This site shows you how to lend on exchanges.
I think the risk of the exchange being forced to halt all withdrawals outweighs the rewards of incremental gain. Chad September 13, Rolf September 13, The outlet provides 30 amps, but one miner needs about 7. If you plug the miner directly into the outlet you are not maximizing the use of your electrical infrastructure. Tonykkk September 24, To each his own. I like the flexibility.
And a network switch wherever I want. Michel November 21, 5: Great article Rolf, can you provide some fotos too? At Bitmain mining facilities I see they create 1to1 with airflow controls where 2 racks front each other and inbound air blows from above between them inflow lane , the space between is roughly 1 shelved rack width, and on the backs you have the outflow lane where racks face each other back to back for outflow..
Tyler November 21, 6: Hydro Quebec is offering as low as 2. Michel November 21, 6: Lucas September 16, 8: How many rigs will i be able to run smoothly in the house assuming that no other electric appliances are running at the same time? Rolf September 17, Theoretically you could have Practically, your breaker will probably pop at a sustained amperage of 80Amps, your electric wiring will be inefficient, and you probably have other demands on the electricity at your place.
What do you think? Do you think i should look for a warehouse with greater power supply instead? Or this is viable for a small size miner like me? If you prefer to use 4 outlets instead of 1 outlet and a PDU, go for it.
When you fill up your house with rigs and your main breaker pops a few times a day then it is probably time to find some other space. Octavs December 21, 8: Next month, when I receive 4 more, I am moving into a warehouse…: John September 21, 8: For mining facilities over 50 miners that doesnt work or thats for PC kind of devices? Also, I dont see you recommending any Routers, do you connect the switch directly to the firewall?
You use a layer 3 switch? Or meraki provides routing capabilities? With a partner we are building a mining facility and could use your help on it. Find a local data networking reseller and get their help would be my recommendation. I am confortable running a flat network up to hosts. Meraki MX64 will handle miners easily. Find a local Cisco reseller and get some consulting help if you need it.
Cameron Bruce October 1, 3: I live in a RV, and am looking for information about setting up a mining operation I can take with me wherever I decided to go. Todd Abraham October 1, 4: You should check out the immersive cooling system from GR Cooling. They can fit S9s into a 20 foot shipping container, complete with cooling tanks, power, and a fibre glass evaporative cooler.
Graig Sterling November 27, 7: Hi Todd Thank you for this excellent tip,this cooling system can be the answer to the 3 most debilitating bitcom mining problems witch are: Your tip was most helpful,cheers! Craig October 1, The problem I see wth that is where are you going to get power from? Octavian October 12, Great article Rolf, but… regarding cost of electricity in Quebec, this is also from their site:.
Yes, you read that right. And the other costs are definitely lower in Quebec. So if anyone is interested in opening a farm in Quebec, email me. McKaig October 15, 8: Rolf October 16, 3: I have found I am not very good at reading electricity rate sheets. And that the more I use, the lower the price goes. They have so many charges, it is crazy! I agree Quebec is good for mining, for many reasons. Or maybe I will set up a mini-hydropower plan in the mountains somewhere, do line of sight wifi, and build a mining facility off the grid.
Octavian December 21, 9: Rolf, sorry for missing on your comments… Been busy with receiving my miners, setting them up and buying 3 more for a friend who provides me temporary hosting.
Quebec is like Iceland but closer to home…: Electricity may be slightly more expensive, but the real estate is dirt cheap, by your standards. Patrick October 19, So no sort of transformer is needed to convert it to single phase, right? Ken October 19, 2: If you have a 3 phase system it has 3 hot wires.
If you use two of them together you get v which is then capable of running a single phase load like a power supply. The three phase machines you are referring to are designed to take all three hot lines at once and are typically large mechanical devices like motors.
Patrick October 19, 2: Does this change the calculation at all regarding the amp draw? Ken October 19, 3: Yes, you have the Right idea. You will get considerably more miners into a 3 phase panel vs single for the same amperage.
Patrick October 20, 9: So for several Antminers getting power from a 3 phase supply, does the PDU need to be 3 phase since that is what it is plugged into or single phase since that is what the Antminers are? Tripp Lite has both 3 phase and single phase PDUs.
Ken October 20, 4: When you break out a 3 phase panel into v circuits, the individual circuits are seen as a single phase. Google 3 phase basics. From a practical standpoint for mining, all it means is that you are going to hire an electrician to wire up a bunch of v 30a circuits that you will plug in your PDUs single phase.
The fact thaat your facility has 3 phase means you can wire up more of those circuits and use more miners than a comparably sized single phase panel. Patrick October 21, 2: I had a few questions regarding miner temperature regulation and monitoring.
Do you make adjustments in response to a high temperature when all 3 boards are high, or does only 1 need to be high before making adjustments? How relevant do you think measuring and changing static pressure is on managing chip temperatures? Rolf October 27, 8: There are not a lot of adjustments to make. If the S9 overheat first they produce errors, then they shut down.
If that happens you need more airflow or more cooling. I prefer to have both intake and exhaust fans, which provides static pressure. If you use intake fans only you have positive pressure, exhaust only negative pressure.
Gary October 26, 1: This is a great article Rolf, thank you for writing it up. Do you mind sharing what bank that is? I have not had a problem with banks connecting to coinbase or kraken. Al October 30, I am looking into adding a separate v box with amp service and whole house surge protection. Rolf October 30, Do what you like. John October 30, 9: Is it possible to rewire them to V with minimal construction? I know you can pull single phase VAC off the three phase transformer.
John November 8, Hey Rolf, after running one S9 in my house, I decided to run 10 of them in my warehouse. And now the order is expired when in fact I see the balance in the order address. After doing some research I saw that so many people are having trouble with their orders. Customer support seems to be non-existent. How did you manage to get hundreds of miners from Bitmain!?
Rolf November 13, I have had good luck with Bitmain. They are a little behind on their service, but if you buy from them I find they ship to you. If you need to you can open up a support ticket with them. You may need to go back and forth a little but they have always been good for me. Anton November 6, Hi, sorry for my ignorance. The louver you listed has much lower intake CFMs that the fan. I noticed quite a bit amount of louvers having lower CFM throughput than the fans of same size.
Rolf November 6, Anton November 7, Michael November 6, 3: I live in a country that still has no regulation on bitcoin mining, so setting up that kind of business will be tricky. Konstantin November 12, 5: Can you explain how to minimize the taxes? JD Parry November 12, 7: Hi, I believe Rolf was referring to finding a good accountant to show you how to depreciate your equipment miners, etc… over time as a tax right off.
Exactly — and it depends on how taxes are calculated in your country. For the US, if you show only losses and no income every year it gets kind of suspicious. Michael December 9, Depending on your gear, taking the full depreciation in the first year makes sense sometimes instead of a depreciation schedule.
Depends on your profit too. Majkara November 15, 2: Have you considered mineral oil submersion cooling? We have 10 miners right now and when we expand to we are definitely considering putting these beasts in a small swimming pool with mineral oil and just extracting the oil into a pair of big radiators with big fans on top of them. Would love to hear your thoughts on this or if you experimented with this.
Rolf December 27, 6: Nick K November 17, 1: Hi Rolf, thank you for this great article. It let me clear understanding of workable steps.
Patrick November 22, 9: I saw your YouTube video of your medium sized mining farm when you were replacing the filters. It looked like you custom made a way to hold filters in front of the fan. How has that affected your fans, if at all? Nick November 26, 1: I am starting a 15xD3 farm in my basement here in Canada I have the power plumbed and the networking and cooling done. What I am wo dering is when these x11 script miners our no longer profitable for x11 coin mining is it worth keeping them for other applications?
What do you current miners do with old hardware? Sell it on ebay as a paperweight? Ken November 26, 6: Ken November 27, 2: Does anyone have any suggestions on getting a facility? Patrick December 8, Carl November 29, 4: Hi Rolf, I am currently setting up a mining operation. If that is correct…I can run 4 antminers off a 30 amp breaker?
Trying to figure out what breakers to get and how many miners I can run per breaker. The building is wired with V three phase. I am having the electrical upgraded to amps. Octavian December 30, 5: I ran them for a month and the breaker never jumped. Not recommended as a setup, but just to emphasize that 6. Nick November 29, 7: Rolf, with Bitmain releasing new batches, they seem to be selling further out from the date of shipping.
I know you said not to buy pre-orders but how are you suppose to get the machines if the only reasonable price is a pre-order from Bitmain? This is in contrast to an established company that runs a production schedule that takes orders for future batches a few months in advance.
Bitmain seems to have a few months from first availability to shipping but they actually come through and ship the products they sold you. But buy from someone who has a track record of shipment and support, like Bitmain. Nick K December 2, 1: Is this device suitable for a farm of 20 s9 ASICs? I am going to use it along with port LAN switch. First of all, thanks for the great post, and sharing all this knowledge and experience, well done.
In my case, I have no other options than using an air conditioner, i guess. So, with cheap electricity, and the room available to me, what are my chances of running 20 Antminers S9?
What are the things I need to consider or watch for? Can I do hot isle isolation, and let a fan push the air out? In this case, how much of cooling and CFM do I need? That is a LOT of air. For 20, that is CFM in and out of the room. AL December 7, 1: What is the best way to set up a Cisco Meraki Wireless Firewall unit? Planning Your Bitcoin Mining Operation — https: Nick Loe December 14, 3: One of the most important things you will need before using any kind of Bitcoin mining software is a wallet.
This is because all Bitcoin mining software will ask you for a Bitcoin address that will be used to send your mining rewards and payouts. Once you create or download a wallet you will be able to get a Bitcoin address from your wallet.
There are many Bitcoin wallets , but these are the ones we recommend if you are just starting out:. If you expect to earn a lot of money through mining then it would be smart to purchase a more secure wallet: You can use Bitcoin Miner on Windows 10 and Windows 8. It has an easy to use interface, power saving mode, mining pool support and fast share submission.
One useful feature is the profit reports feature because this feature will help you know if your mining is profitable or not. The latest version of this software is Bitcoin Miner 1. CGMiner is arguably the most famous and commonly used among Bitcoin miners at the moment.
