Bitcoin mixer mistakes to avoid

Most privacy failures happen after the mix, not during it. These are the errors that give the coins away.
Consolidating mixed and unmixed coins
Spending a mixed output together with a KYC output in the same transaction proves the two belong to one owner and destroys the anonymity set you just paid for. Keep mixed coins in a separate wallet with coin control enabled.
Round amounts and instant withdrawals
Depositing exactly 0.5 BTC and withdrawing exactly 0.5 BTC minus a visible fee minutes later is trivially matchable. Use a delay, accept non-round amounts and split payouts across addresses where the service supports it.
Reusing addresses and leaking metadata
Reusing a withdrawal address, pasting it into a support chat, or checking it on a public explorer over clearnet all re-link the funds. Fresh address per payout, Tor for lookups, and no screenshots of the transaction anywhere.
