# Guide: Bittery

**Bittery** combines CoreDAO non-custodial BTC staking with an on-chain lottery mechanism — giving you the chance to win the full yield from the lottery while keeping your BTC safe and locked in your own wallet. All users keep full control of their BTC, and one lucky winner takes home all the rewards.
