Why buy from Open Source Miners?

We don't sell anything we don't run ourselves: our own fleet mines around the clock on the exact hardware in this shop.

Open firmware instead of a black box

Bitaxe, Nerdaxe and NerdQaxe are open-source Bitcoin miners: the Bitaxe runs AxeOS, the Nerdaxe family runs NerdOS, a fork of it. Every setting is visible, and clock and voltage are yours to set. Flash firmware updates in minutes with our free web flasher, right in the browser and without extra software.

In stock in the EU, shipped within 24 hours

Every miner marked as available is in stock and ships within 24 hours with tracking, with no customs fees and no import-VAT surprises. Shop availability is always up to date; if something sells out, the restock alert notifies you first.

Support from miners, for miners

We run Bitaxe and NerdQaxe miners around the clock ourselves. Questions about solo mining, pool setup, WiFi or cooling are answered by someone who has the same device on their own desk. In English or German.

Bitcoin only, and you can pay with it

Our miners only compute SHA-256 for Bitcoin. We carry no altcoin miners and make no "cloud mining" promises. Pay by Lightning or on-chain, by card or PayPal, as a guest without an account.
