The question is for Kruw and the developers of mixers that use the services of blockchain analysis companies. If all UTXOs are "guilty until proven innocent", how can users refute evaluations that are "false-positives"?
They can't, because
you can't prove a negative.Or "we can't". Because from their viewpoint if it's a validated positive, then it's a good illustration of the effectiveness of blockchain analytics. But if a "tainted" UTXO passed through, then it's merely an illustration that the blockchain analysis company should set up more filters.

The hypothesis that there might be two different prices between KYC-Bitcoin and "tainted" non-KYC-Bitcoin might start being a real issue when BlackRock and the other institutions/asset managers truly come in, no? Perhaps in five years?
