The Best Bitcoin Miners for Home in 2026: Which One to Buy

The best Bitcoin miner for home in 2026 depends on what you want from it: for most people it is the Bitaxe Gamma, an open-source single-chip miner with 1.3 TH/s at 17 W that is set up in minutes. If you want the smallest possible start, the NerdMiner V4 mines at 250 KH/s on about 1 W and is the device to learn with; if electricity is your main worry, the NerdAxe Gaia at 10 J/TH is the most efficient miner we sell. If you want the most hashrate one device can bring into a home, the NerdOctaxe Rev 3.1 is the strongest air-cooled miner in our range at 12 TH/s, and the NerdOctaxe Hydro reaches 14 TH/s with a closed water loop.

This guide explains what makes a good home miner, how to read hashrate, power and efficiency on a spec sheet, and which of the eighteen miners in our catalogue fits which budget and use case. Every device figure comes from our product pages. Prices and stock change more often than an article does, so you will find them on the product cards and in the miner comparison, not in the text.

Our picks at a glance

• First ASIC miner and best all-rounder: Bitaxe Gamma, 1.3 TH/s at 17 W on a board small enough for any desk, set up in minutes.
• Smallest start: NerdMiner V4, built on the official NerdMiner V2 board, mining at 250 KH/s on about 1 W from any USB port.
• Quietest miner: Bitaxe Gamma with the Noctua fan, which its product page lists at under 12 dB.
• Lowest electricity per terahash: NerdAxe Gaia, 2.6 TH/s on 25 W from the BM1373 chip, which is 10 J/TH.
• Most hashrate on a desk: NerdQAxe++, four BM1370 chips for 4.8 TH/s at 70 W in one device.
• Most hashrate at home: NerdOctaxe Hydro, 14 TH/s at 220 W under a closed water loop that keeps it quiet enough for a home.
• Miner and winter heater in one: Avalon Nano 3s, a closed box whose 140 W warm the room in the cold months, with a quiet mode at 33 dB.

What makes a good home Bitcoin miner

A home Bitcoin miner is not a scaled-down version of the machines in a mining hall. Those draw several kilowatts, need a circuit of their own and are loud enough for a garage. A home miner is built for a desk, a shelf or a living room: a small board with one to eight ASIC chips, or in the case of the NerdMiner a single microcontroller, a fan or a water loop, Wi-Fi instead of a rack switch, and a web page instead of a rack controller. Six properties decide whether one of them is a good fit for your home, and every one of them is a trade against the others.

Hashrate

Hashrate is the number of guesses per second a miner makes at the next block, and it is the one figure that decides your chance of ever finding one. The devices in this guide run from 250 KH/s, two hundred and fifty thousand guesses per second on the NerdMiner V4, to 14 TH/s, fourteen trillion guesses per second on the NerdOctaxe Hydro. More hashrate means more lottery tickets in every ten-minute round of the Bitcoin network. It also means more power, more heat and, with air cooling, more fan. Every other property on this list is a trade against hashrate.

Power draw and efficiency

Power draw in watts is what you pay for every hour the miner runs, and it is the only running cost of a home miner. Efficiency in joules per terahash (J/TH) tells you how much energy each unit of hashrate costs; a lower number is better. The BM1370 chip on most current boards lands between 13 and 20 J/TH depending on how many chips share a board and how hard they are pushed, the newer BM1373 in the NerdAxe Gaia reaches 10 J/TH, and the older BM1368 in the Bitaxe 702 needs 21.4 J/TH. Two miners with a similar hashrate can differ by a third or more in their electricity bill, so efficiency is the figure to compare once you have chosen a hashrate class.

Noise and cooling: fan or water

Chips that hash get hot, and the heat has to go somewhere. Most home miners use a heatsink and a fan; the smaller the fan, the faster it has to turn for the same heat, and fast small fans are what people hear. There are three approaches in our range. Single-chip boards such as the Bitaxe Gamma use a small fan and can be ordered with a Noctua fan that the product page lists at under 12 dB. The NerdQX uses a tower heatsink with a 120 mm and a 90 mm fan, the way a desktop computer does, and is the one air-cooled model with a measured noise level in its data sheet, 38 dB. The Hydro models move the heat into a closed water loop and a radiator, which is how the NerdQAxe++ Hydro and the NerdOctaxe Hydro can run six and fourteen terahash in a room you sit in. The Avalon Nano 3s, the one closed appliance in this guide, publishes 33 dB in quiet mode and 38 dB in normal mode. For every other model we publish no noise figure, because we have not measured one.

Size and where it lives

A Bitaxe Gamma measures about 10 by 6 cm and weighs 73 g; a NerdMiner V4 weighs 40 g and runs from any USB port. Both sit next to a monitor. The four-chip and eight-chip boards need a spot with airflow: not a closed cupboard, and not a shelf full of books. Two hundred watts of hashing is two hundred watts of heat in the room, which some owners welcome in winter and everyone should plan for in summer. The Hydro models carry their radiator in the frame and stand on a desk or on the floor without a separate mount.

Setup and firmware

Every miner in our range except the Avalon is set up the same way: power it on, join the Wi-Fi network the miner opens, enter your home Wi-Fi, a pool and your Bitcoin address, save. No software is installed on your computer. The Bitaxe and NerdAxe boards run AxeOS, an open-source firmware with a web dashboard on your home network that shows hashrate, temperature, power and shares, and lets you change pool, frequency, voltage and fan speed. The NerdAxe Gaia Copper Pro runs NerdOS instead, which you also open in the browser. The NerdMiner runs its own open-source firmware and is configured through a setup page. The Avalon Nano 3s is configured from the manufacturer app on a phone.

Open source or closed

Seventeen of the eighteen miners in this guide are open hardware running open firmware: the Bitaxe family from the Bitaxe project, the NerdAxe, NerdQAxe++, NerdQX and NerdOctaxe boards from the same community, and the NerdMiner from Bitmaker. Open source means you can read the code, flash a new release yourself, change every setting and point the miner at any pool, including your own node. The Avalon Nano 3s is the exception: a closed appliance from Canaan that you cannot tune or reflash, in exchange for a sealed box that needs nothing assembled. We stock it for people who want exactly that, and its product page says what you give up.

How to read the numbers on a spec sheet

Product pages and comparison tables throw four units at you. Here is what each one means for a small Bitcoin miner at home.

• KH/s, GH/s, TH/s: thousand, billion and trillion hashes per second. The NerdMiner V4 at 250 KH/s and the Bitaxe Gamma at 1.3 TH/s differ by a factor of about 5 million; that is the difference between a learning device and a real share of the tickets.
• W (watts): the power the miner draws while hashing. Multiply by hours and divide by 1,000 for kilowatt hours, then multiply by your tariff. The formula is worked through below.
• J/TH (joules per terahash): watts divided by TH/s. It is the efficiency of the chip and the board together; a lower figure means less electricity per lottery ticket. It is the figure that separates a good home miner from a cheap one.
• Chips: the ASIC model and how many of them share the board. BM1370 is the current generation on most boards, BM1373 the newest, BM1368 the previous one. More chips on one board means more hashrate from one power supply and one dashboard, at the cost of heat and, with air cooling, noise.
• Cooling: heatsink and fan, tower cooler, solid copper or a closed water loop. It decides how the miner sounds, where it can stand and how much headroom it has for tuning.

One figure you will not find on our product pages is a probability of finding a block. It changes with the network hashrate every day, so we explain the calculation further down instead of printing a number that would be wrong within a month.

The picks by budget and use case

The picks below run from the smallest budget to the most hashrate. Every figure comes from our data sheets; prices are on the product cards, which follow our purchasing rather than this article.

NerdMiner V4: the smallest Bitcoin miner for beginners

The NerdMiner, today our NerdMiner V4, is the device that started home solo mining as a hobby. It hashes at 250 KH/s on an ESP32-S3 microcontroller, draws about 1 W over USB-C and shows hashrate, shares, best difficulty, block height and a clock on a 1.9-inch colour display. It weighs 40 g, sits in a 3D printed case in one of six colours and is set up in about five minutes by scanning the QR code on its screen. The firmware, the case files and the board design are published by the NerdMiner project.

Buy it to learn how mining works, to give away, or to have a working piece of the Bitcoin network on a shelf. Its chance of a block is tiny, and the NerdMiner vs Bitaxe page puts that in numbers against the Gamma. What it will never do is show up on your electricity bill: 1 W around the clock is under one kilowatt hour a month. The NerdMiner category lists the case colours and the spare cable.

Bitaxe Gamma: the classic first home miner

The Bitaxe Gamma is the miner most people should start with. One BM1370 chip, the generation used in the Antminer S21 Pro, delivers 1.3 TH/s at 17 W, which is 13 J/TH, on a board of about 10 by 6 cm with a 0.91-inch OLED display and a 3D printed stand. It ships with a 5 V / 8 A power supply, runs AxeOS and is configured from a browser in minutes with the Bitaxe setup guide.

It is the reference point for every other miner in this article: 5 million times the hashrate of a NerdMiner for 17 times the power, small enough for a desk, and with a fan you can swap for a Noctua fan if the room has to stay quiet. The Bitaxe project is open hardware from the board files to the firmware, and the Bitaxe category has the upgrade kits and cases that fit it.

NerdAxe Gamma: the Bitaxe alternative with a colour display

The NerdAxe Gamma is a single BM1370 miner as well, at 1.2 TH/s and 17 W, and it also runs AxeOS. What it adds is the 1.9-inch colour display of the NerdMiner, which cycles through hashrate, shares, chip temperature and the Bitcoin price and is readable from across the desk. It comes with the standard fan on a stand, with a Noctua fan, or in the NerdAxe case. If you like the Bitaxe but want the display of the NerdMiner, this is the board; the NerdAxe setup guide covers it screen by screen.

NerdAxe Gaia: the most efficient home miner we sell

The NerdAxe Gaia puts the BM1373, the newest chip generation, on the NerdAxe board. A single chip delivers 2.6 TH/s at 25 W, which works out to 10 J/TH, the lowest figure of every miner in our range. It has the 1.9-inch colour display, a 40 mm PWM fan that follows the chip temperature, a 12 V / 6 A power supply and a stand, and it runs AxeOS like the Bitaxe.

This is the pick when your electricity price is what worries you, or when you want twice the hashrate of a Gamma without a second device and a second fan. Per watt it holds the most lottery tickets of anything we sell. The NerdAxe category shows the whole family from the Gamma to the NerdOctaxe.

Bitaxe Gamma Performance and Performance Stage 2: for overclockers

Both are the Bitaxe Gamma board with the cooling rebuilt. The Bitaxe Gamma Performance puts the BM1370 under an ICE Tower cooler with a Noctua fan and runs at up to 1.5 TH/s at 20 W, about 15 J/TH. The Bitaxe Performance Stage 2 goes further with a low-profile cooler with copper heat pipes, a 60 mm Noctua fan on the chip and a second 40 mm Noctua fan behind the board, and reaches up to 2 TH/s at 30 W, the highest hashrate we ship on a single-chip Bitaxe.

They are for people who want to raise frequency and core voltage in AxeOS one step at a time and watch what the cooler makes of it. Overclocking puts more stress on the chip than the stock settings, and the product pages say so. Two more boards for tuners: the Bitaxe Gamma Copper Pro puts one BM1370 under the AXP60 Copper Pro, a full-copper cooler with a 60 mm fan, for 1.5 TH/s at 22 W, and the NerdQAxe Copper Pro does the same for four chips, 4.8 TH/s at 80 W with a 60 mm and a 92 mm fan. If you are not planning to tune, the plain Gamma or the Gaia gives you more hashrate per euro of electricity at stock settings.

NerdQAxe++: the desk miner with four chips

The NerdQAxe++ is the four-chip board of the NerdAxe family: four BM1370 chips, 4.8 TH/s at 70 W, about 15 J/TH, the same efficiency class as a single chip on its own. It has the 1.9-inch colour display with three views, runs AxeOS and sits between a single-chip Bitaxe and the eight-chip NerdOctaxe in hashrate as much as in the space and airflow it needs. For most people who have outgrown a Gamma, this is the next step: one device, one power supply, one dashboard, and almost four times the tickets. The NerdQAxe++ setup guide applies to the whole family. To stand the board upright there is the NerdQAxe Stand, and the NerdQAxe Performance Case protects it without closing in the heatsink.

NerdQAxe++ Hydro: a quiet Bitcoin miner with water cooling

The NerdQAxe++ Hydro runs the same four BM1370 chips under a water block. A pump moves the heat into a radiator, where a larger fan disposes of it slowly; the loop arrives filled, bled and tested, and the frame holds board, pump and radiator as one unit. Because the chips stay cool they hold their clock: 6 TH/s at 100 W, 16.7 J/TH, from the same silicon that does 4.8 TH/s air-cooled. This is the quiet Bitcoin miner for the room you work in, with a 12 V / 10 A supply included.

NerdQX: eight terahash behind a tower cooler

The NerdQX takes the opposite route to the same goal: four BM1370 chips, 8 TH/s at 140 W, 17 J/TH, cooled by a tall finned heatsink with a 120 mm intake and a 90 mm exhaust fan, the way a desktop computer is cooled. Big fans turning slowly are quieter than small fans turning fast, and the NerdQX is the one air-cooled miner in our range with a measured noise figure, 38 dB. It stands upright on its own base with the airflow front to back, has a colour display on the front and runs AxeOS with defaults set for continuous running rather than a benchmark number.

NerdOctaxe Rev 3.1: the strongest air-cooled home miner

The NerdOctaxe Rev 3.1 is the strongest air-cooled miner we sell: eight BM1370 chips on one board, 12 TH/s at 200 W, about 17 J/TH, one power input, one display and one AxeOS dashboard. The fan speed follows the chip temperature. Two hundred watts of heat need a ventilated spot, not a closed cupboard, and the product page says plainly that anyone buying a miner this size should do the electricity sum first. It is the pick for solo miners who want the most hashrate one air-cooled device can deliver.

NerdOctaxe Hydro: 14 TH/s at home

The NerdOctaxe Hydro runs the same eight chips under a closed water loop and reaches 14 TH/s at 220 W, 16 J/TH, the most hashrate we ship for a home. The loop carries the heat to a radiator, where a large fan disposes of it slowly, and in winter that heat warms the room it stands in. It comes with a 12 V / 20 A power supply and, like every board in the family, is set up in a browser. The odds for one device are still long, which is the nature of solo mining, but the difference between one and fourteen terahash is real: about eleven times the tickets of a Gamma in every round.

Bitaxe 801, 702 and Gamma Hex 1300: more chips on a Bitaxe board

The Bitaxe 801, sold by the manufacturer as the Bitaxe GT, puts two BM1370 chips on one board: 2.15 TH/s at 43 W, about 20 J/TH, with a 12 V / 5 A supply and a stand. It is the step for people who run a single-chip board, like the setup and the noise, and want more hashrate without a second miner on the shelf. Two chips sharing one cooler run warmer than one, which is why the efficiency is a little worse than that of a Gamma.

The Bitaxe 702 uses six chips of the previous generation, the BM1368, for 4.2 TH/s at 90 W and 21.4 J/TH. It gives you the most hashrate per euro in our Bitaxe range and costs the most electricity per terahash. It makes sense with cheap electricity, a solar surplus or a workshop that wants the heat; at a high tariff around the clock, a Gamma or a Gaia costs less per terahash over a year. The product page says that before you order.

The Bitaxe Gamma Hex 1300 goes furthest: six BM1370 chips, the chip of the Bitaxe Gamma, on one board under a closed water loop, with an 80 mm fan at the back for the voltage regulators. Its data sheet lists the overclocked operating point, 10.5 TH/s at 200 W and 19 J/TH; at its factory setting it runs at 8.4 TH/s on 150 W and 17.9 J/TH, and you choose between the two in AxeOS. That makes it the strongest Bitaxe we sell, with a 12 V power supply in the box.

Avalon Nano 3s: the only closed device in this guide

The Avalon Nano 3s is a sealed appliance from Canaan, a manufacturer that has built ASIC miners since 2013: twelve 4 nm chips, 6 TH/s at 140 W, 23.3 J/TH, in a housing the size of a shoebox that runs from a single USB-C power supply and is configured from a phone app. It publishes two noise levels, 33 dB in quiet mode and 38 dB in normal mode.

You give up open firmware, tuning and the browser dashboard, and you pay over half again as much electricity per terahash as a BM1370 board at 15 J/TH. You get a box that arrives sealed, starts on the first try and never asks a question. If you do not want to learn anything about mining and just want a machine that mines, this is the one; everyone else is better served by an open board.

Home Bitcoin miner comparison table

Every miner in our catalogue with the hashrate, power draw, efficiency, chips and cooling from its product page, sorted by hashrate. Current prices and stock are on the product cards and in the miner comparison.

Mining in a flat or apartment: 230 V sockets, noise and heat

A home miner does not need a house with a garage. Every miner in this guide runs in a flat, and five things decide which one suits the room you live in.

• The socket: an ordinary wall socket, in the EU 230 V, is all any of these miners needs. None needs a circuit of its own or a special power connection: each runs through its power supply, the NerdMiner V4 from a USB port. Even the largest miner we ship, the NerdOctaxe Hydro, plugs into a normal socket with its included power supply, and its product page compares its draw under load with that of a games console.
• Power draw: from about 1 W for the NerdMiner V4 and 17 W for a Bitaxe Gamma to 220 W for the NerdOctaxe Hydro. It sets your electricity bill, worked out in the next section, and the heat the miner leaves in the room.
• Noise at night: in a bedroom or a one-room flat this matters most. The Bitaxe Gamma with the Noctua fan stays under 12 dB according to its product page, quieter than most rooms are at night, and the Avalon Nano 3s runs at 33 dB in quiet mode. The NerdQX is listed at 38 dB, audible in a silent bedroom but not in an office, as its product page puts it. The Hydro models push their heat through a large, slow radiator fan; under full load, its product page says, the NerdQAxe++ Hydro sounds like a quiet desktop computer rather than a hair dryer.
• Heat in the room: a miner turns all of its electricity into heat. A NerdMiner is not noticeable; a NerdOctaxe releases 200 W into the room, and the product page of the Hydro compares its 220 W to a small electric heater. In winter that is a feature, in summer it is something to plan around with airflow. If you want a miner to heat a room in winter, read our page on the Bitcoin heater.
• Space and air: the NerdMiner V4 and the single-chip boards fit next to a monitor. The four-chip and eight-chip boards need a spot where warm air can leave, never a closed cupboard, and the radiators of the Hydro models need free air.

These are the miners to look at first for a flat, with power draw, noise and power supply as listed on each product page:

For a bedroom or a desk you sit at all day, take the Bitaxe Gamma with the Noctua fan. For more hashrate in a room you work in, the NerdQAxe++ Hydro brings 6 TH/s at 100 W under water. If the miner should also warm a room in winter, the Avalon Nano 3s is the closed box with a quiet mode, and the NerdOctaxe Hydro gives the most hashrate and the most heat. Where the table says no figure, we have not measured one, so the product page names none.

What it costs to run a Bitcoin miner at home

Electricity is the only running cost of a home miner, and the sum is short: watts × hours ÷ 1,000 × your price per kilowatt hour. A month has about 720 hours, so the monthly consumption in kWh is watts × 0.72. Your tariff is the variable in that formula; take it from your last bill, because it differs by a factor of two or more across Europe.

As an example only, at 0.30 EUR per kWh, the miners above cost per month:

• NerdMiner V4, 1 W: 0.72 kWh, about 0.22 EUR
• Bitaxe Gamma, 17 W: 12.24 kWh, about 3.67 EUR
• NerdAxe Gaia, 25 W: 18 kWh, about 5.40 EUR
• NerdQAxe++, 70 W: 50.4 kWh, about 15.12 EUR
• NerdQAxe++ Hydro, 100 W: 72 kWh, about 21.60 EUR
• NerdOctaxe Rev 3.1, 200 W: 144 kWh, about 43.20 EUR
• NerdOctaxe Hydro, 220 W: 158.4 kWh, about 47.52 EUR

At 0.20 EUR per kWh the figures are a third lower, at 0.40 EUR a third higher. Efficiency is what moves the bill for a given hashrate: the Gaia at 10 J/TH and the Bitaxe 702 at 21.4 J/TH cost very different amounts for the same terahash. If your tariff is high, buy efficiency; if you have solar or a cheap night tariff, hashrate per euro of hardware matters more than J/TH.

Realistic expectations from solo mining at home

Solo mining at home is a lottery, and this guide would be dishonest if it said anything else. Bitcoin adds a block roughly every ten minutes, and the miner that finds it receives the block reward, currently 3.125 BTC plus the transaction fees of that block. Your chance of finding any given block is your hashrate divided by the current network hashrate. The expected time until a block is the current network hashrate divided by your hashrate, times ten minutes. The network hashrate changes every day, so look it up on a block explorer and do the division yourself; we do not print a probability here because it would be out of date within weeks.

What the formula tells you without any numbers is how the devices compare with each other: a Bitaxe Gamma holds about 5 million times the tickets of a NerdMiner in every round, a NerdQAxe++ almost four times the tickets of a Gamma, and a NerdOctaxe Hydro about eleven times. It also tells you what does not matter: the age of the device, how long it has been running and the best difficulty on its display change nothing about the next hash. Every ten minutes is a new draw with the same odds.

Plan for no block. Most home miners never find one, and that is the honest expectation, even though it does happen: in July 2024 a Bitaxe found block 853742, a story we tell in our article on that block, and in July 2026 a single Bitaxe with about 1 TH/s found block 957382, according to the pool it mined on. What you get in any case is real hashrate contributed to the network, a live view of mining on your desk and a small but genuine chance at a full reward. The solo Bitcoin mining guide goes through the odds, pool choice and running cost step by step, and the Bitcoin lottery miners page lists every miner that fits the description.

Pool mining is the alternative and works on every device here: point the miner at a shared pool and it earns a tiny, steady share instead of a rare full reward. For the smallest devices the share is too small to notice, which is why their owners choose solo; with the four-chip and eight-chip boards both modes make sense. Solo or pool is one field in the settings of the miner, and you can switch at any time.

Setup in minutes

Every open-source miner in this guide connects to a 2.4 GHz Wi-Fi network and is configured in a browser: power on, join the network the miner opens, enter your Wi-Fi, a pool and a Bitcoin address that belongs to you, save. All our miners come preset to a public solo pool, so a first setup only needs your address. After that you control the AxeOS boards from a dashboard on your home network; the NerdMiner keeps its settings on the setup page. We have written a guide for each family:

• NerdMiner setup guide for the NerdMiner V4, and the NerdMiner pool page for pool address, port and what to check when the miner stays at 0 KH/s
• Bitaxe setup guide for the Gamma, Gamma Performance, Performance Stage 2, Gamma Copper Pro, Gamma Hex 1300, 801 and 702
• NerdAxe setup guide for the NerdAxe Gamma, the NerdAxe Gaia and the NerdAxe Gaia Copper Pro
• NerdQAxe++ setup guide for the NerdQAxe++, NerdQAxe++ Hydro, NerdQAxe Copper Pro, NerdQX and both NerdOctaxe models
