Wissen rund um Bitaxe, Nerdaxe und Solo Mining
Bitcoin mining guides: Bitaxe, solo mining and open-source miners
Alle Anleitungen, Guides und Vergleiche an einer Stelle: von der ersten Einrichtung über Pool und Firmware bis zu Kühlung, Stromkosten und der Frage, welcher Miner zu deinem Setup passt.
This hub gathers the most important guides for Bitaxe, Nerdaxe, NerdQaxe, solo mining and running your own Bitcoin infrastructure. If you want to buy a miner, set up a rig or simply understand open-source mining better, start here.
Home mining comes down to three decisions: which device fits your space and power budget, how you set it up, and how you keep it healthy in daily operation. This hub is sorted exactly that way. Everything here comes from working with the devices we sell and support ourselves.
If you are just starting out
- Bitaxe miner guide – what a Bitaxe is, what it does and who it is for.
- Open-source Bitcoin mining – why open hardware and firmware matter in mining.
- Understanding solo mining – how it works and what expectation is realistic.
Finding the right miner
- Buy a Bitcoin miner – every model with hash rate, power draw and context side by side.

- Bitaxe or Nerdaxe? – the two families compared directly.
Setting up – step by step
Each guide runs from unboxing to the first accepted share, with screenshots from AxeOS.
- Set up a Bitaxe – Wi-Fi, pool, wallet and the first readings to check.
- Set up a Nerdaxe Gamma
- Set up a NerdQaxe
Firmware, AxeOS and tools
Our web flasher installs current AxeOS firmware straight from the browser – optionally keeping your configuration, so Wi-Fi, pool and Bitcoin address survive the update. No Python, no command line.
- Bitaxe Flasher – install firmware in the browser, for every AxeOS device we sell.
- Pool configurator – the four AxeOS values for our solo pool, ready to copy.
- Troubleshooter – from fault to cause in three clicks.
- Mining calculator and network dashboard – power cost, block chance and difficulty, live.
- AxeOS firmware update – when an update is worth it and how to do it safely.
- AxeOS explained – every dashboard reading and what it tells you.
- Overclocking – more hash rate without losing the temperature battle.
In operation: pool, cooling, electricity
- Choosing a pool – solo pool, classic pool or your own node.
- Making it quieter – fan curve, heatsinks and what actually helps.
- The right power supply – when the included one is enough and when it is not.
- Calculating electricity – what continuous operation really costs per month.
When something goes wrong
- Troubleshooter – to the cause in three clicks, with hand-over to support.
- Connected but not mining – checking router, pool and network in order.
- Understanding the hash rate error – what the AxeOS value means and when it matters.
- Support page – the common cases plus a direct line to us.
Solo mining and your own infrastructure
- How likely is a block? – the honest maths for every model.
- Running your own Bitcoin node – why it is worth it and what it takes.
- Point your miner at your own node – Public Pool on Umbrel, step by step.
Products that fit
If you want to build a setup after reading, these are the usual starting points:
- Bitaxe Gamma 601 – the compact entry into open-source mining.
- Bitaxe Copperzilla – the same board with solid copper cooling.
- NerdQaxe++ – four ASICs, noticeably more hash rate.
- NerdQaxe++ Hydro – water cooling for quiet continuous operation.
- LiquidBox V5 – a Bitcoin full node for sovereign infrastructure.
Frequently asked questions
What is a Bitaxe, exactly?
A Bitaxe is a small Bitcoin miner with open hardware and open firmware (AxeOS), built for a desk, a shelf or a homelab rather than a mining farm. A single ASIC does the hashing, an ESP32 controller runs the browser interface. You enter pool and Bitcoin address yourself – no provider settles anything on your behalf. Details in the Bitaxe miner guide.
Does home mining pay off financially?
As a predictable investment: no. At typical electricity prices a home device earns less than it consumes, purely on the maths. What you get instead is a ticket in every draw – if your device finds a block, the full reward goes to your address – plus heat in the room and a device that helps secure the network. If you are after a return, this is the wrong hobby; if you want to understand Bitcoin and take part, it is the right one. Run your own numbers in the mining calculator.
How much electricity do these miners use?
It depends heavily on the model: the small single-chip devices sit in the low tens of watts, a NerdQaxe++ around 80 W, a NerdOctaxe about 200 W. Practically all of that leaves the device as heat – welcome in winter, an argument for another room in high summer. Concrete costs are in calculating electricity.
Do I need technical knowledge?
No. Setup runs through a web interface: enter your Wi-Fi, add pool and Bitcoin address, done – a few minutes, no PC skills and no command line. If you want to go deeper later, frequency, voltage and fan curve are all adjustable. The setup guide shows every step with screenshots.
Solo mining or a pool – which makes more sense?
A pool pays small shares regularly, though with a home device those shares are tiny. Solo mining pays nothing almost all of the time – and the entire block reward in the rare event of a hit. For most home miners solo is the more honest option, because it treats the thing as what it is: a lottery with very good side effects. The solo mining guide puts both in context.
How loud is a miner in a living space?
The small models with a 40 mm fan are audible in a quiet room but unobtrusive; from the 4.8 TH/s class upwards a device is clearly present and does not belong in a bedroom. The fan curve in AxeOS lowers the level at the cost of temperature headroom. What actually helps is in making a Bitaxe quieter.
What do I need besides the miner itself?
A socket, a 2.4 GHz Wi-Fi network and your own Bitcoin address. Power supply and stand are included with our devices, and no extra PC or Raspberry Pi is needed – AxeOS runs on the miner itself. Hardware only comes into play once you want to mine against your own node; the node guide covers that.
How do I keep the firmware up to date?
Easiest through our web flasher: pick the device, plug in the cable, install – with the checkbox set, Wi-Fi, pool and Bitcoin address stay intact. Alternatively download the update files and apply them in AxeOS under System. Whether an update is worth it at all is covered in the update guide.
