Frequently Asked Questions

How do I set up my BC 01?

Simply connect it to a USB-C PD power source and follow the WiFi configuration steps in the included manual. Setup typically takes less than 5 minutes.

What is a "Lottery Miner"?

A lottery miner is a low-power device that attempts to solve a block solo. While the odds are small, the reward for success is the full block reward (currently 3.125 BTC + fees).

Can I overclock my BC 04?

Yes, our hardware supports custom firmware for overclocking, though we recommend using our official performance profiles for optimal longevity.
