FAQ
Common questions about the Nerdminer & solo mining
What is a Nerdminer and how does it work?
A Nerdminer is a tiny solo bitcoin miner for your home. Instead of joining a pool against industrial farms, it tries on its own to find a whole bitcoin block, which is what people call the bitcoin lottery. If it finds one, the full reward (currently more than €190,000) goes to you. How that works in detail is in the guide What is a Nerdminer?.
Is solo mining with the Nerdminer V2 actually worth it?
On the maths alone the block chance is very small. The appeal is the real possibility of a win at minimal running cost, plus what you learn from running your own miner. We work the odds and the expectation through honestly in the bitcoin solo mining practice guide and in the solo mining calculator.
How much electricity does a Nerdminer use?
The Nerdminer V2 draws only about 1 to 2 watts, which is a few euros of electricity a year. We measured it rather than estimating it: Nerdminer V2 power draw. For the more powerful model there are measured figures for the NerdNOS.
Do I need technical knowledge to set up the Nerdminer?
No. Our devices arrive preconfigured and are ready in 3 minutes: switch on, join the Wi-Fi, store your bitcoin address, done. The full guide with screenshots is here: Setting up the Nerdminer V2. If the Wi-Fi plays up, try the Wi-Fi troubleshooting guide.
