I am not in favor of mixers, predicted their demise here, and laughed at the clowns who were defending them for a paycheck. That being said, mixers can’t be replaced with non-KYC exchanges. The thing about non-KYC exchanges is that when they get enough user funds, they turn into KYC exchanges and then steal everyone’s money. If this hasn’t happened to you yet, it will if you keep using them.
