Buy open-source Bitcoin miners – fast premium shipping
At Open Source Miners you get open-source Bitcoin mining hardware for the home: from the compact Bitaxe Gamma 601 through the NerdQaxe ++ to the powerful NerdOctaxe with up to 12 TH/s. Every device runs the open AxeOS firmware – no vendor lock-in, no manufacturer account, no black box. Hardware you truly own. Not sure which model fits? Our miner comparison lines them all up by hashrate, power draw and price.
Why open mining hardware?
Bitaxe, Nerdaxe and NerdQaxe are based on the efficient BM1370 ASIC and are deliberately open: you control pool, frequency and voltage yourself and watch hashrate and temperature in real time. That makes them ideal for solo mining and for everyone who wants to not just hold Bitcoin but understand and actively support it.
