If you are asking cryptocurrency that can be mixed using the exchange, well I can say that it is not possible. Because if you know that another exchange can mix cryptocurrency, maybe that platform is a scam, or maybe doing illegal activities that you don't know where your crypto could possibly be in danger.

But if Bitcoin mixing using the exchange, as far as I know and understand it is possible. That's why it can also be used as an exchange in some cases. Like they use blockchain analysis or the ip address used when transactions were made.
