A Bitcoin mixer, also known as a Bitcoin tumbler, is a privacy-enhancing tool that helps users obscure the origin and destination of their Bitcoin transactions. Since the Bitcoin blockchain is completely transparent, every transaction is permanently recorded and publicly viewable. This transparency, while promoting trust and verification, also means that anyone with the right tools can trace a user’s transaction history and potentially identify them based on wallet activity. A Bitcoin mixer works by collecting Bitcoin from multiple users, combining (or "mixing") them together, and then redistributing an equivalent amount of Bitcoin back to each user from the mixed pool. The key is that the coins returned to the user are not the same ones they deposited. This process breaks the direct link between the sender and the receiver, making it extremely difficult for anyone—including blockchain analysts or third parties—to trace the transaction path. bitcoin mixer
