Regular cryptocurrency transactions are traceable and can be sufficiently proven by exchanges. If the coins you bought were involved in illegal activities (such as black market transactions), a crypto exchange could freeze your funds even if you weren’t complicit in that behavior. The traceability of blockchain transactions and KYC verification exercise make it possible for crypto exchanges to figure out and reveal the identity of persons involved in a certain blockchain transaction. With mixers, the idea of untraceable cryptocurrency transactions is possible. Cryptocurrency mixers help you stay private as you transact on the blockchain, keeping your dealings away from the public eye, preserving your identity, and obscuring sensitive information on the transactions you have made.
