Greetings, dear readers!
Bitcoin's weekly growth from $9,500 to $12,000 (at the time of writing) once again inspires crypto enthusiasts. Probably some of you are already seriously thinking about making money on cryptocurrencies and, as an option, mining cryptocurrencies. In this article I will show the assembly of a mining farm (in fact, there is only 1 rig, but rigs are often called farms).
How to build a mining farm from scratch?
To receive money, relatively speaking, out of thin air, you will need strong determination, free space and capital for entry. This is not a financial pyramid - this is cryptocurrency mining, a complex and demanding business that will bring stable passive income.
A computer and a video card in it will help you get started. To make a profit, you will need to buy a couple of video cards and find a place for a mining farm.
Cryptocurrency can be mined on central processors and video cards. You can start mining on working video cards from Nvidia or AMD. You can also mine on a CPU, for example Ryzen or chips from Intel.
Another issue is profitability. To ensure a consistently high level of profitability, you will need at least four video cards.
Cryptocurrency mining on video cards
The easiest option for people who want to make a profit and don’t want to bother. Typically, the farm is assembled on video cards from Nvidia 10 series, such as 1080 and 1080 Ti. There is also a more budget option, for example, mining on RX 4xx and 5xx series video cards.

Cryptocurrency mining on processors
When the network complexity is low, they consider mining coins on the central processor. The CPU supports mining any coins based on the PoW algorithm, such as SHA-256, Cryptonight, X11, Ethhash, Scrypt and Equihash.
The profitability of mining on the CPU is low.
What can be mined on a central processor
- BTC - Bitcoin, cue ball, Beethoven, aka coin No. 1, aka the product of the thoughts of the anonymous Satoshi Nakamoto.
- BCH - Bitcoin Cash, a fork of Bitcoin. Coin rate and analytics on CoinGecko.
- LTC - Litecoin, technically identical to Bitcoin. Coin rate and analytics on CoinGecko.
- DOGE - Dogecoin, a project that began as a joke coin, has grown to become valued in real money. Coin rate and analytics on CoinGecko.
- DASH - Deshcoin. Coin rate and analytics on Coingecko.
- Monero is XMR, a completely anonymous cryptocurrency. Course and analytics on CoinGecko.
On the CPU you can also mine coins that are usually mined on video cards: ETC, ETH, XZC.
Let's start mining
After the miner has assembled the farm himself, it needs to be launched. But experts say that you don’t have to rush into this until you check the functionality of the supplied equipment. This can be done using the AIDA64 program. This program is a simple and effective software that provides comprehensive data on all components that will take part in mining. When the check has shown that the mining farm you created yourself is connected and working adequately, you can mine cryptocurrency.
But starting a farm is not as easy as it seems at first glance. This is a sequential process that only seems simple.
In particular, we tried to divide it into several mandatory steps:
If we make a mining farm with our own hands, we can install a program that overclocks video cards to earn 10-20% more. For example, you can choose MSI Afterburner for this.- It is also advisable to have a program that will allow you to remotely control your computer, because you won’t sit around your farm all day long and wait for the money to drop in. Therefore, having a program like TeamViewer will make life much easier.
- Professionals recommend installing the HWiNFO64 program, which is needed to monitor the system. But this is not necessary - it will just make mining activities a little easier.
- Select the cryptocurrency and the pool in which you will mine it. Of course, solo mining is also possible, but when creating a home farm for cryptocurrency mining, a pool is the best solution. In this way, you guarantee yourself a stable profit, even if you have to fight for it not on your own, but in company with other users.
Having selected a cryptocurrency in the pool, find the “Help” section (although this depends on the pool you are joining) and download the miner.- In the downloaded program, in the “start.bat” file, write down the wallet address, the name of your farm and your email for notifications.
When the software is ready, we launch the farm. This type of coin mining was in demand in 2019, and it looks like nothing is planned to change in 2022.
What types of mining farms are there?
Let's start with the distribution of cryptocurrency farms by the complexity of their assembly. Conventionally, farms can be divided into three sizes - domestic, medium and large.
Home farm, ordinary
- one rig hidden on the balcony. Used ones are used. computers, or hardware from mezzanines, adapted to work with 1050 or RX 480. Up to 4 cards, low profitability, payback slowly - in a year or two. A home rig can bring the owner an additional 100 - 250 dollars a month.
The farm is average and well-fed.
There are six cards per rig, and five to six rigs for the entire farm. Designed to partially replace the employer, functioning as a source of additional income. Can generate profits from 500 to 1200 dollars per month.
The farm is large and well-fed.
Large mining installation for 12 - 20 rigs. Requires a separate building; a converted barn, garage or dugout will do. During the construction of the farm, a separate transformer booth should also be provided - such a farm consumes about 4 kW-hour, but also brings in from $5,000 per month.
What is a rig?
It's like a USB hub - one device for several connectors. A rig is an assembly consisting of one motherboard, RAM, processor, a number of risers and video cards. An average rig requires 4 video cards, but more are possible. The physical limit is 8 cards per rig.
What is a riser?
An extension cable that will help connect four video cards to one motherboard. Under normal conditions this is impossible.
Asic controllers - which is better
Asic controllers are equipment that has come to replace mining on video cards. Powerful devices that can even mine Bitcoins, although not in such large volumes as a few years ago. They were created for one purpose - to make a profit. But these Asics also cost a lot. Although, if you buy a ready-made, powerful computer, the power of which is several times higher than similar installations created on the basis of video cards, then the expenses will pay for themselves quite quickly.
In addition, assembling farms not from video cards, but based on such controllers is much simpler and more profitable. But the investments are also more impressive. The price of one powerful device starts from one and a half thousand dollars. This is a lot for a novice miner, which is why not everyone uses this type of equipment. It is simply not affordable for everyone, even given the vague prospects for the price of Bitcoin to rise in the future.
That is why there are no fewer miners with homemade farms on video cards, even taking into account that this mining method has not been so popular and effective for a long time. We can say that ASICs are noticeably more profitable in almost all respects, but they are only suitable for one algorithm. Video cards can be switched for mining different currencies.
If the ASIC breaks, you can only throw it away, while the broken part in the farm can be replaced and continue to work.
Assembling a mining farm with your own hands: selection of components
You should start by choosing a location for your mining farm. If with the “home” everything is prosaic - a balcony, a basement or a storage room - then starting from the average farm it is recommended to carefully select the location.
The farm has a “body kit”, it consists of a processor, SSD, motherboard, RAM and power supply. You will also need to select a riser for the farm.
Mining motherboards
Choose a motherboard that suits your budget; the requirements for power phases are low, but there are requirements for materials. Select video cards based on their elemental base; for example, cards from China are not suitable for mining. American options will serve well, for example motherboards from Gigabyte, Asus and Biostar.
The main task of the motherboard is to serve video cards.
Budget mining boards for 4 video cards
- ASUS H81M-PLUS, CPU socket: 1150;
- MSI 970A-G43, CPU socket: AM3+
- FM2A88X
Motherboards for 5 video cards
- Gigabyte GA-F2A88X-D3HP, socket FM2+
- Gigabyte GA-970A-DS3P, socket AM3+,
- Gigabyte GA-970A-UD3P, socket AM3+
- GA-A55-S3P A55-S3P, socket FM1
Motherboards for 6 video cards
- ASRock H81 PRO BTC R2.0, socket 1150
- GIGABYTE H110-D3A Bitcoin Edition, socket 1151
- BIOSTAR TB85, socket 1150
Motherboards for 12+ video cards
- Biostar TB250-BTC TB250, socket 1151
- ASRock H110 Pro BTC+ Bitcoin, socket 1151
When choosing a motherboard, pay attention to the socket - this is the connector for the processor. For example, a board with LGA1151 will not fit an FM1 processor.
Processor for mining motherboard
The role of the processor in a mining kit is as a spacer between video cards and the hard drive. All calculations are performed on video cards; the processor practically does not deal with the payload. Since the CPU is engaged in non-computational tasks in mining, there is no point in choosing an expensive model.
CPU requirements for mining
- 4 cores
- 2.5 - 3 GHz
- Single thread by CPU-z: from 100
- Multithreading by CPU-z: from 350
The technical process, year of production and core model do not affect the hashrate. There are no requirements for the size of the CPU cache; the processor must be present. But there is no need to push two cores from Dual Core either.
Recommended CPUs for a mining rig
Blue processors
- Intell Celeron, Pentium or i3 models. Depending on processor availability in your market. Choose something that is inexpensive and has at least four streams.
Red processors
- Athlons, Phenoms, FX and other 4-thread CPUs. For example FX-4100 for socket AM3.
Farm hard drive
- Any 60 GB SSD from your store. The mining results are formulas, they don’t take up much space, but the system will work faster on an SSD.
RAM for mining
- Any 4 GB, no matter DDR3 or DDR4. Video cards do not work with the memory on the motherboard, they have their own.
Power supplies for mining
For convenience, we recommend using modular power supplies, to which you can connect only the necessary cables. When mining there will be a lot of wires, they will be different. A classic power supply does not always have, for example, space for 4 MOLEX expansion cables.
Recommended brands of power supply: Zalman, Chieftek. In general, any adequate power supply with a modular connection from 500 W will do.
Recommendations for selecting risers for a mining farm
Take those that are powered through a MOLEX port, as these are power ports designed to withstand high loads. Other types of ports will not withstand the voltage and will lead to PCB burnout. Do not use adapters from the box with a riser from SATA to MOLEX - they will burn out.
When connecting risers via a MOLEX power cable, do not connect more than two risers to one power cable, even if there are enough connectors for 4.

“We are at the very start”

— How and when did you learn about cryptocurrencies?
— I learned about cryptocurrencies in 2011. Then it was just a good time to enter this topic. In general, it’s not too late now.
Less than 1% of the population has crypto wallets. That is, now we are, no matter how funny it sounds, at the very start.
People have a chance to figure it out in time and gain advantages over those who will figure it out later. In five to ten years we will see 20% instead of 1%. And the rate will then be significantly higher .
I first heard about cryptocurrency on the Ekho Moskvy radio. But I didn’t do anything, I had to figure it out, try mining. We laughed with the system administrator and postponed the question for later. Then it came only in 2016: it became clear that this is the technology of the future .
— For those who don’t know, tell us where it all begins? What is needed to create a crypto farm?
— You need to have cheap electricity. But there are tariffs for individuals and for legal entities. In Irkutsk, for example, there is a good tariff for individuals (about 1 ruble per kilowatt-hour), this is five times cheaper than in Moscow. But this is for personal needs, not for business; Our power engineers are fighting mining at the rate for individuals .
The tariff for industry (network voltage 110 kV and above) is about 3 rubles per kilowatt. Compared to the rest of the world, this is also a competitive price.
In general , mining is a normal business , like any production, only the production of digital goods. Of course, it’s no longer possible for everyone to be overwhelmed with gold.
- Okay, cheap electricity. What else is needed?
— Specialized computers for mining. They are sold abroad. To import, you need to go through customs. Well, or you can buy it here.
— How much did you initially invest in creating the farm?
— I didn’t invest in one day, and it was a long time ago. Maybe $100,000 or $50,000 for the first purchase. I took money from my brother and made a farm for him. To invest, he sold his apartment. Not the one in which he lives, of course.
Digital gold. What is cryptocurrency - using Bitcoin as an example
How to set up equipment for a mining farm
It’s easier to watch the video instructions for assembling the farm once.
- Inspection of components.
- Using Wi-FI Sockets.
- Using a monitor plug for video cards.
- Mounting RAM.
- Mounting the SSD.
- Connecting the power supply to the system.
- What is a riser and how to connect it
- How to start a computer without connecting the power button.
- Assembling the mining rig housing
- Windows installation
As an alternative to Windows, we recommend installing NiceHash OS, the installation of which is simplified to the maximum. Setting up a farm comes down to creating a bootable USB flash drive and... that's it. There are no tricks, we tried it ourselves, there is an addiction, my brother is alive.
The bonus is that NHOS supports all modern hardware, while Windows 7 does not work with some devices without dancing with a tambourine.
Basic nuances during assembly
And yet, how to assemble a farm? In an ideal case, video cards are installed on a remote rack, and coolers for airflow are attached to the structure on several sides. The maximum number of cards connected to a computer is 6 pieces - these are the capabilities of modern motherboards. But before you create a mining farm, there are many details to consider.
The next issue that the future miner needs to solve is energy consumption. If we are assembling a mining farm, then this becomes a matter of first importance. The fact is that, with all their energy-saving improvements and reduced process technology, video cards consume a huge amount of current. If you are planning to build a mining rig from scratch, then electricity costs should also be taken into account - they will be very high.
The minimum power of devices in the mid-price segment with not the best computing power is 50 watts per hour. For top-end solutions, the more relevant figure is 100 W per hour, which when multiplied by 6 (the maximum number of slots) gives an impressive 0.6 kilowatts. Creating a mining rig will force you to consume current almost like any household appliance.
But this is not all that those who want to build a farm need to know. The installation cannot work on its own - in fact, it is the same computer as everyone else, only with expanded capabilities. Therefore, we also add the central processor, RAM, hard drive and coolers on the racks and inside the system unit.
All of the components listed above can add another 200–400 watts, which in ideal conditions gives 1 kW per hour. Or about 24 kilowatts per day - for some citizens this is the consumption rate per month per person. Creating a mining farm will turn you into a current consumer comparable to a small office. Don’t forget about the dimensions of a do-it-yourself mining farm. The dimensions would be comparable to a small diesel generator or something similar. The size of an ASIC-based mining rig can also be huge. Some installations weigh up to 25 kilograms.
How to choose a location for a mining farm
Technical requirements for a farm site:
- You can reach the place in an hour.
- The farm site is isolated from outsiders.
- Only you or a very narrow circle of trusted persons with whom you have no conflict of interest know about the place. For example, when a father-in-law loves gambling, he should not be trusted with information about the farm.
- You have the keys to the farm site and free access to it.
- The farm room has ventilation, windows or an exhaust hood.
Should you put a farm in the garage?
A garage in an area that is known for lock picking is a good choice with extreme caution. Don't take risks.
When there are few alternatives to the garage, it is recommended to strengthen the gate by welding steel rods - this will help prevent penetration into the room.
How to strengthen a garage?
Detailed video instructions on how to strengthen your garage against break-ins. You will need gas welding and glasses, only for real men.
Additional precautions when choosing a site for a farm
- You can freely carry out repair work in the place for the crypto farm. This means replacing double-glazed windows with chipboard panels for ventilation, installing chipboard panels in the room.
- The room or building for the farm is located in close proximity to power lines. For example, you can install a transformer booth or carry out additional. power line.
- You have legal grounds for installing equipment and carrying out repair work. For example, you bought a plot or we are talking about premises in an apartment with documents.
- You cannot legally take away a plot of land for a crypto farm. For example, when the barn belongs to the neighbor’s cousin, and you convert it into mining installations.
- Consider installing CCTV surveillance cameras. They will be needed to monitor the situation near the farm.
What is suitable for a farm, gradation of premises
- Apartment
. It’s bad, noisy, stuffy, not enough space, perfect for a home farm. - Warehouse space
. Rented warehouse, garage or apartment without renovation with good ventilation. - Grandma's dacha
. It’s a good idea, and it’s safe if there’s a barn on the property—it can be converted into a farm building.
Technical requirements for the premises
- At least 15 square meters.
- Ventilation.
- Availability of copper wiring.
- Possibility to connect an additional power line to the panel.
Pensioners, students and schoolchildren mine

— How did your environment react to the fact that you started mining?
— When I started, there was even less acceptance and even more doubt. Although gradually many of my friends also joined this business. Moreover, it is quite democratic: pensioners, students, and schoolchildren all mine.
Mining is very easy to organize at home or in the garage.
At first there is distrust, then people begin to calculate with a calculator and also begin to try. When there is a good example , you want to join something cool and profitable.
— What difficulties and risks are there in mining?
— Many things are incomprehensible to a person who is just entering this business. There is no linear mathematics here. People ask me what the rate of return is, what the profitability is, how to make a business plan . I say: “Throw it all away.” There are no linear dependencies here.
There are things like network difficulty, which depends on how many miners there are in the world. There is such a parameter as the Bitcoin exchange rate, this is another unknown. I can calculate all this quite approximately, using my knowledge of the cyclical nature of processes. And a person who is just entering the market usually starts counting linearly with a calculator, but his result is only suitable for a math problem.
This is the whole difficulty. But people definitely need to enter this market, at least buy cryptocurrencies for their wallet on their phone, in order to start understanding it and start practicing.
This is a different logic and a slightly different world altogether. And you need to get used to it. This is a different way of working for the brain. But it's okay, it's simple.
— What income do you get from mining?
— I don’t want to talk about my income. Now there is a new law, according to which all this will need to be somehow legalized. But there must be income from any business, otherwise they would not be doing it.
You can make any money from this. You invest in equipment - you earn. Or invest by buying cryptocurrency.

Selection of materials for the farm body
In addition to electronics, the rig also contains a housing. In order not to purchase system units each time, miners assemble a frame from aluminum corners.
Example of a frame for 8 video cards.
Wooden frames are a fire hazard - when heated, there is a risk of ignition of the wood, which serves as a fastening element of the structure.
An example of assembling a frame for a farm using a perch for a riser.
About using wood to attach risers
The option is exclusively voluntary and fire hazardous. It is used for convenience - after cutting holes in the aluminum profile, the card is mounted on self-tapping screws in the wood. If the riser under the video card burns out, only the wooden profile will be damaged, the rest of the frame will remain intact. The risk of burnout is reduced if the risers use a MOLEX connector.
Motherboard
The main element of a mining farm is the video card. In our case there will be three of them, so it is necessary to have three PCIe slots of different types, for example, X1 or X16. There is no big difference here.
As a motherboard, you can buy one of the cheap Intel versions. The main thing is that it has the required number of inputs for the video card. Alternatively, you can buy GA-H61M-DS2, 1155 socket. Today its cost is about 3500-4000 rubles. You can also take a cheaper motherboard that is suitable for the tasks at hand.
The board is almost the cheapest for this socket, it has only 3 power phases per processor, but it will suit us.
Frame drawings for a crypto farm
Below are drawings of frames for a rig for 5 and 8 video cards. Frame materials: aluminum, wood. Ordinary bolts and nuts are suitable for fastening parts.
Standard screw, hex head, full thread.
Crypto farm assemblies use ordinary screws from a hardware store with a Phillips head.
Tools for assembling a housing for a mining rig
- Straight arms.
- Screwdriver.
- Drill and set of drills. Need 4 - 6mm
- Screwdriver, Phillips or flathead.
- A set of screws of the same size.
- Saw on wood.
- Hacksaw for metal.
- Clamp or vise.
- Pliers for tightening nuts.
- Optional - sanding tools for wood processing.

Drawing of a farm frame with video cards
The holes for video cards are cut at a distance of 10 cm. The lower central spacer is used to secure the power supply and motherboard. Keep in mind that after assembly you will need to place additional fasteners for the format of the motherboard and power supply you have chosen.
An example of a farm drawing for 8 video cards
To secure the motherboard and power supply it is convenient to use a sheet of chipboard. When mounting the power supply, it is recommended to place it with the fan up or to the side to ensure ventilation.
Where is a good place for a miner to live?

— What mistakes do novice miners make?
— The first mistake is to buy yesterday’s generation equipment , the same Antminer S9. Give or take a year from now it will have to be thrown away.
The second is to ignore that there is no linear story here. If you buy expensive equipment, its value can easily drop a hundredfold in just a year.
Another danger is buying equipment with viruses from an unscrupulous seller. You'll have to change the motherboard.
There are many pitfalls. Like any other business, it has its own characteristics and nuances.
— You call Irkutsk the capital of mining. Is it possible to mine profitably in other regions of Russia?
— There are no official statistics. But according to the statistics we collected, Russia accounts for 20% of global mining. Of these, about half are in the Irkutsk region.
Yes, you can mine in other regions. In Moscow, for example, mining is very good using stolen electricity. There are many institutions, state corporations, where no one can account for electricity, and system administrators can easily plug in miners that will operate from the general network. It won't be noticeable. Just think, 5% was added.
If you have free electricity, you can mine anywhere.
I know that there are people who do mining on gas equipment where gas is cheap. I think that new technologies for obtaining energy from some interesting source will soon appear, which can also be used for mining.
Promising bitcoin: what the cryptocurrency market will be like in 2021
What to consider when planning a room for a crypto farm
The premises will need to be re-equipped when launching a large
crypto farms, where 10 - 20 rigs are working simultaneously indoors, with 5 video cards on each. The heating level is appropriate - you will need an air circulation speed of 5 l/hour.
A stand of two rigs will need sufficient airflow from room fans and ventilation through room windows. For a home farm, cooling on the balcony and blowing through coolers is enough.
Distribution of rigs among stands
When assembling a farm, several rigs can be combined into a stand. The stand serves as a regular rack, which you can purchase or assemble yourself.
The room is zoned to achieve an optimal ventilation configuration and reduce heating of the equipment. Two factors are taken into account - heat rises and the stands will need help moving the hot air.
An example of a utility rack that is suitable for holding 4 rigs at a time.
The location of the rigs in the stand is not important; when blowing, hot air will rise upward along with the direction of the air flow.
Ventilation of stands in the room
Racks should be placed near a fan to remove hot air from the rigs towards a vent or window. Large farms are equipped with a double ceiling with an exhaust hood that removes hot air to the street.
It is recommended to equip the stand with a purge fan to ensure ventilation. Ventilating the entire room is rational only if the windows are replaced with a cooling unit.
A home air conditioner is not capable of handling the heat levels from a farmhouse, so its use is not recommended.
The windows in the room used to maintain the mining farm can be converted into a ventilation duct. A sheet of chipboard is selected to match the size of the window, holes are made in it for mounting two 500mm turntables, after which they are mounted for blowing. The gap between the frame is filled with foam to seal the structure.
Processor, RAM and fans
The Celeron G530 series is suitable for the above motherboard. This is the best option in terms of price and quality. In addition, it consumes little electricity and, accordingly, the load on the power supply is reduced. Additionally, you can save on the cooling system. The cost of these devices on the secondary market is minimal. And, if you search, you can find an option for 300-500 rubles.
The price is such because no one needs these stones at all
To cool such a processor, just put enough thermal paste on it and attach a compact fan on top. This design is sufficient to remove heat and ensure normal operating temperature. Moreover, in some cases, the Celeron G530 series can operate without a fan at all. At the same time, there is much less noise.
In addition to the processor, you will need a radiator for 300 rubles (easy to find for free) or buy a cooler in a complex for Socket 478, remove the fan from it and use it for the CPU. In this case, the costs are unlikely to exceed 50-100 rubles.
The next important device is RAM. It is advisable to have at least 4 GB of RAM on board, which is enough for a farm. We give preference to DDR3 2 GB (two sticks). The cost of such equipment is about 1000 rubles.
The price there is indicated per plank, so we calculate for a pair of planks - 1000 rubles
How to arrange stands in a room
Miners use a ceiling hood using a suspended ceiling made of chipboard and a slot for a fan.
An example of the location of rigs indoors.
The fan can be replaced with 120mm coolers to drive hot air towards cooling coolers located on the ceiling. The diameter of the ceiling fan is from 400mm to 500mm, installation is for exhaust from the room.
Wiring requirements for maintaining mining rigs
You need copper wiring, aluminum is not suitable. In new buildings from 2005, copper is used, in Stalin and Khrushchev buildings, aluminum wiring is used.
If the wiring is aluminum, then try making copper wiring from the panel to the truss. Risk? High. This is a complete collective farm and cannot handle anything more than a home farm.
When 15 kW is allocated to a room, do not use everything from one outlet - this is dangerous, it will not withstand it.
A harsh Russian LED signals an overload from the farm.
- In old apartments with aluminum wiring, power supply is limited to 2 - 3 kW, where 1 kW is required for household appliances. In houses with old wiring there is room for 12 cards of the 1060 or RX570/580 level at max. reducing their power consumption.
- If the apartment has or has previously installed an electric stove, then the issue with the load disappears.
- 1 kW of farm consumption requires 300 cubic meters. meters of air.
power unit
Now let's look at the block that will power the equipment. Here you can get the MWE 750 W Cooler Master. Such a power supply is easy to find in stores, it is reliable and has an optimal distance between the four connectors - 6+2 Pin (12 cm). The relatively small power of 0.75 kW allows you to reduce energy consumption and, accordingly, electricity bills.
Basic features of the power supply:
- ATX form factor;
- power - 0.75 kW;
- ATX version - ver. 2.52;
- active PFC - present;
- Efficiency - about 90%;
- certification - 80 Plus Gold;
- average work is 100 thousand hours.
750 W of power is enough to connect four GPUs without load problems. As for the processor, it consumes no more than 5-7 W. The cost of such a block is about 8,000 rubles. It’s better not to save money here, but to buy new equipment.
Payback and profitability of a mining farm
What kind of profit can you expect from a cryptocurrency farm? Stable, of course. But be mentally prepared that the farm will be profitable in the first year or two. From the third year, the farm brings net profit; usually a 6-card rig can bring in 3-4 thousand dollars a year, or ~250 dollars a month.
When planning your farm budget, set aside a portion of the profits to provide power to the farm. For example, three months in advance to provide installations with electricity in the event of a cryptocurrency decline.
Set aside 10% of your production every month for a safety net, which will allow you to flexibly build a strategy for the development of your farm and its safety.
Should I start mining in 2022?

Publication from Yuri Dromashko (@dragon_u_rich)
— Is it worth starting mining now?
— In 2022 it’s already late. Equipment prices are already very high. I would advise starting in 2023, when prices will be very low. As I say, there is non-linear logic here , you need to be on topic. As a self-help story to help you figure this out, yes; as a story for making money - hardly.
- Is it worth buying?
Yes, cryptocurrency is absolutely liquid. You can buy it, and then sell it on the exchange any day for crypto-dollars, thereby fixing your profit.
Now is a good time to buy - it’s a bullish year, the crypt will continue to grow strongly.
— What are you doing with cryptocurrency? How do you remove it and what do you store it in?
— I love bitcoin, ether, dash . These are the cryptocurrencies in which it is good to hold capital in 2022. And for transactions I use stablecoins (cryptocurrencies, the rate of which is tied to the reserves of regular currencies; they are less volatile). For example, USDT is priced at one dollar. They are convenient to transfer money to another person.
Withdrawing and selling cryptocurrencies is very simple. There are even special ATMs in the USA. Although I think they are expensive.
Naturally, I store my wealth in crypto. It is much more reliable than in a bank. And the stock market is now overheated.
How to buy, sell and exchange cryptocurrency using Bitcoin as an example
Legality and risks of mining farms
From the point of view of Russian legislation, cryptocurrency mining is not considered a criminal offense. Remember the first rule of fight club?
The police tend to conduct raids on mining farms in order to seize property for their own benefit.
However, an attempt to withdraw cryptocurrency from subjects legally controlled by the Russian Federation may be considered a reason to initiate a criminal case. Large turnover may result in prosecution on suspicion of money laundering.
The last known incident occurred in 2022, when, under Article 172, Part 2, a criminal case was opened against three people for exchanging bitcoins worth over 500 million rubles. Purchasing cryptocurrency for cash is regarded as a reason to initiate a criminal case for violation of the Law “On Digital Financial Assets”.
Analysts believe that cryptocurrencies will experience stable growth over the next decades.
conclusions
As can be seen from the above figures and calculations, the profitability of mining as an independent enterprise with large investments is practically absent. Now even a do-it-yourself mining farm is unprofitable. The year 2022 promises very few prospects for those who want to earn serious money. No, no one is stopping you from using your own computer power to replenish your wallet with a small amount of free coins. But investments in such an enterprise do not pay off very well or pay off with great difficulty. A home mining farm in 2022 will only become a source of not very large earnings and serious worries.
But still, there is little prospect for DASH miners - this cryptocurrency is showing good growth rates. Accordingly, the above periods may be reduced in proportion to the increase in the exchange rate. Here the 2017 mining rig is relevant, although there is one caveat. Whether you are ready to rely on a vague forecast of rising costs is up to you to decide.

Online farm
In 2015, the opportunity to virtually rent a farm became available. There are companies that provide appropriate equipment that can be used for Bitcoin mining for a fee. One of the disadvantages of this scheme is the high risk of stumbling upon deceivers, since everything is built on trust.
The payback period for this method of making money is approximately 6 months. It is suitable for beginners who do not have enough money to build their own farm, but want to start somewhere. It's important to use this method as a stepping stone to getting your own equipment and not as an ongoing way to make money.
How the farm works
The essence of this installation is the mathematical calculation of successful actions within the system. After calculating the most optimal action, the system makes the necessary transaction and receives electronic currency (bitcoin) for it.
Accordingly, the more opportunities a farm has, the more modern and high-speed equipment is integrated into it, the faster and more successful its decisions will be. Accordingly, her earning potential will be higher.
Please note: in addition to directly earned bitcoins, there is also a special commission issued for successfully adding operations to a block.
Each block takes approximately 10 minutes to form, and all connected miner installations work to create it. Accordingly, the more devices are connected, the more options will be considered.
Bitcoins can be mined in two ways:
- An independent mine using your own bitcoin farm. The disadvantages are quite expensive equipment that not everyone can afford.
- Association with other users with a special pool. Small income commensurate with the invested power. But it does not require additional investments.
