tumbler bitcoin

A **Bitcoin tumbler** (also known as a **Bitcoin mixer**) is a service or tool that improves privacy by mixing potentially identifiable cryptocurrency funds with others. The goal is to obscure the trail between the sender and recipient by breaking the link between a user’s Bitcoin address and their transactions. Tumblers achieve this by pooling together coins from multiple users, shuffling them, and redistributing equivalent amounts—usually minus a service fee—to new addresses.

While some people use tumblers to maintain financial privacy, they can also be used for illicit purposes such as money laundering, so their legality varies by jurisdiction.
