The basics
What Are Bitcoin Mixers?
Bitcoin mixers — also called tumblers or crypto mixing services — break the visible link between the address that sends coins and the address that receives them. Every Bitcoin transaction is recorded forever on a public ledger, so anyone who learns one of your addresses can follow the trail: your balance, your income and everyone you pay.
A mixing service pools coins from many users and returns different coins of equal value, minus a fee, to fresh addresses. Done well, it restores what cash has always offered: fungibility. People use them to keep salaries confidential, protect donations, separate business and personal funds, and avoid becoming a target after a large purchase becomes public.
It is worth being clear about what mixing does not do. It does not make coins invisible, and it does not erase their history — it adds a break that makes the history much harder to read. How strong that break is depends on the size of the pool, the delays you choose, how the amount is split and how carefully you handle the coins afterwards. That is why we rank services on process and transparency, not on marketing claims about “total anonymity”.
