The NerdMiner V2 Pro and the Bitaxe Gamma both mine Bitcoin solo at home, but they answer very different questions. Here is which one fits you.
Short answer: buy the NerdMiner V2 Pro if you want to learn how Bitcoin mining works on a 1 W gadget that sits on your desk and holds a real but tiny chance of a block. Buy the Bitaxe Gamma if you want actual hashrate: its BM1370 chip delivers 1.3 TH/s at 17 W, about 17 million times the 75 KH/s of the NerdMiner, for a far better shot at a solo block. We stock both, and both ship from the EU with VAT included.
The rest of this page puts the two devices side by side: hashrate and odds, power and running cost in euros, firmware and setup, noise and size, and five typical buyers with a clear recommendation for each.
Device data from our product pages, odds and electricity figures calculated as explained below. Current prices and availability are on the product cards further down.

Hashrate is the number of guesses a miner makes per second. The NerdMiner V2 Pro makes 75,000 guesses per second (75 KH/s) on an ESP32-S3 microcontroller, a chip made for Wi-Fi gadgets, not for mining. The Bitaxe Gamma makes 1.3 trillion guesses per second (1.3 TH/s) on a BM1370, an ASIC from the Antminer S21 Pro generation that does nothing but SHA-256. Divide the two and you get the whole story: the Gamma is about 17 million times faster.
In solo mining your chance of winning a block is your hashrate divided by the network hashrate. On 23 September 2026 the network hashrate was about 920 EH/s, and one EH/s is a million TH/s. For the Gamma that works out to about 1 in 708 million per block, or an expected 13,500 years between blocks. For the NerdMiner it is about 1 in 12 quadrillion per block and an expected 230 billion years. Both numbers are averages, not countdowns: the chance is the same every ten minutes, and a block can come on the first day or never.
What this means in practice: nobody should buy either device to get rich. The Gamma is a genuine lottery ticket that is drawn every ten minutes for a few euros of electricity a month. The NerdMiner is a lottery ticket too, but the honest reason to buy one is to watch mining happen on your desk, read the shares and best difficulty on the display, and understand what the big machines are doing at scale. The odds for every miner we sell, with the formula, are in our solo Bitcoin mining guide.
Electricity is the only running cost, and it is where the two devices are furthest apart in absolute terms and closest in what it means for your bill. A month has about 720 hours, so monthly consumption is watts times 720 divided by 1,000:
| Power draw | kWh per month | 0.20 EUR/kWh | 0.30 EUR/kWh | 0.40 EUR/kWh | |
|---|---|---|---|---|---|
| NerdMiner V2 Pro | 1 W | 0.72 | 0.14 EUR | 0.22 EUR | 0.29 EUR |
| Bitaxe Gamma | 17 W | 12.24 | 2.45 EUR | 3.67 EUR | 4.90 EUR |
The NerdMiner costs less to run for a year than a single coffee. The Gamma costs about as much as a streaming subscription per month at the higher tariff, and it delivers 17 million times the hashrate for 17 times the power. Per hash, the Gamma is by far the more efficient machine; per euro on the bill, both are small enough that nobody will notice them.
The NerdMiner draws its power from any USB port or phone charger, so it can live next to a router or a monitor. The Gamma comes with its own 5 V / 8 A power supply; use that one, because a power supply that sags under load is the usual reason for random restarts.
Both devices are set up the same way and take about five minutes: plug in, join the setup network the miner opens, enter your 2.4 GHz Wi-Fi and your Bitcoin address, save, restart. Neither needs software on your computer, and both come preset to a solo pool, so the first shares appear within minutes. The step-by-step walkthroughs with screenshots are the NerdMiner setup guide and the Bitaxe setup guide.
The difference is what you get afterwards. The NerdMiner runs the open-source NerdMiner firmware: the colour display shows hashrate, shares, best difficulty, block height and a clock, and the settings live in the setup portal. The Bitaxe runs AxeOS, also open source, with a web interface in your browser: live hashrate, temperature, chip frequency and voltage, pool settings and firmware updates, all from any device on your network. If you like to tinker with frequency and voltage, the Bitaxe is the one that lets you.
The NerdMiner V2 Pro weighs 40 g, sits in a 3D printed case in one of six colours and runs quietly from a USB port. It is a desk object first: people put it next to the monitor, on a shelf or in a display cabinet, where the colour screen is the point.
The Bitaxe Gamma weighs 73 g, measures about 10 by 6 cm and stands on its 3D printed stand with a fan over the BM1370. With the standard fan you hear it in a quiet room, the way you hear a small desktop fan. With the Noctua option it stays under 12 dB, which is quieter than most rooms are at night, and the hashrate is the same either way. Keep the fan side clear so warm air can leave, and it will run in a living room, a study or a bedroom without drawing attention.
The NerdAxe Gamma is a single BM1370 miner as well, with a colour display like the NerdMiner and hashrate like the Bitaxe Gamma, so it sits between the two devices on this page. The NerdAxe Gaia moves up a class with a BM1373 chip and 2.6 TH/s, and the NerdQAxe++ and NerdOctaxe put four and eight chips into one box. Hashrate, power draw and efficiency of every miner we stock are in one table on our miner comparison page, and the whole family of small solo miners is described on our Bitcoin lottery miners page.
