Need to eliminate that for P2P. my thoughts so far is:
 - make sure the funds are coming from exchange with KYC
 - move over to Monero and Zcash and conversation to btc. but If im not wrong ZEC has some issues with traceability.
 - other option is to receive small amount of BTC directly on  verified exchange wallet with 0 balance. if it not gets suspended - coins are clean and can be received with no worries. In this case question is - how soon your wallet gets suspended if you receive flagged coins and does it depend on amount (50 cents or over 100$).
 Please add your thoughts.

Decentralization slowly moving towards centralization . But that's another topic.
