Cryptocurrency Mixing
Mixing breaks the on-chain link between where your coins came from and where they go next. This page covers the concept and how the main methods differ — wallet-level CoinJoin steps live in the Bitcoin Privacy guide, and the trustless BTC→XMR path is in the Atomic Swaps guide.
How Mixing Works
Mixing combines your coins with others' so an observer can no longer follow a straight line from your deposit address to your withdrawal. The method determines who holds your coins during the process — and that is the key difference between the options below.
Methods
- CoinJoin (recommended) — wallet-level steps and tool names (Wasabi, Samourai) are in the Bitcoin Privacy guide
- Centralized mixers — see the warning below before using one
- Atomic swaps to Monero (best) — see the Atomic Swaps guide for the trustless BTC→XMR process
Centralized mixer risk: a centralized mixer holds your coins during the mix — you send BTC to their address and trust them to return different coins later. That is a custodial relationship: the operator can simply keep your funds (exit scam), and many historical mixers have done exactly that. Some have also turned out to be law-enforcement honeypots that logged deposit and withdrawal addresses. CoinJoin keeps you in control of your keys throughout; atomic swaps lock funds in smart contracts instead of handing custody to a third party.
