No matter how much you use mixers, if you don't learn to use coin control you can be deanonymized. Coin control prevents addresses from joining together. The problem with bitcoin mixers is that even though a mixed transaction should be anonymous in terms of address, it can still be deanonymized through amount analysis or through tracing participants when they start joining their own inputs together. Coin control prevents wallets from automatically joining addresses, which allows mixed transactions to remain anonymous. Wasabi Wallet, for instance, uses coin control and a donation mechanism to confuse blockchain analysis tools and to maintain anonymity.
