A tumbler is a service used to enhance the privacy of cryptocurrency transactions. It works by mixing different users’ coins together, making it difficult to trace the origin of any specific transaction. When you send your coins to a tumbler, they get pooled with others’. This process breaks the direct link between your wallet and the coins you receive back. After the mixing is complete, you get a different amount of coins sent to a new address, further obscuring the trail. This technique can help users maintain their anonymity and protect against unwanted tracking. However, it’s important to note that while tumblers can increase privacy, they also raise ethical and legal questions. Some jurisdictions may view their use as suspicious due to potential links to illicit activities. As with any privacy tool, users should weigh the benefits of anonymity against the possible consequences of using such services.
