Do you believe the future of Bitcoin involves people doing background checks on the coins they are about to receive? So if I want to sell my bike for Bitcoin, I need to ask the buyer to tell me the address/addresses they will pay from and what's the origin of the coins, so I can check if they are in any way tainted. But keep in mind: we don't know what Wasabi and their analysis companies consider taint, and we have no idea what they are looking for. Only they do and they will tell us when our coins are rejected.
