Tumbling refers to the process of mixing cryptocurrencies to enhance privacy and anonymity. Users send their coins to a service that mixes them with others. This makes it difficult to trace the origin of the funds afterward.Typically, users want to obscure their transactions for various reasons, such as avoiding tracking by authorities or maintaining personal privacy. When coins are mixed, the original coins are broken apart, shuffled, and redistributed. Ultimately, the user receives a different set of coins than the ones they initially sent.While tumbling can protect privacy, it also raises concerns. Some malicious actors use tumbling to launder illicit funds. This can lead to regulatory scrutiny and a risk of being flagged by exchanges or other services.In general, tumbling serves as a tool for maintaining anonymity. Yet, users should be aware of the legal and ethical implications involved in its use.
