In the case of Mixers, there can't be a "White line", If the mixers do that, then it won't be decentralized, and people won't use them obviously for privacy reasons, I can't think of any solutions for it.
It isn’t decentralized now. That’s my whole point and what those bashing me by saying I’m not making sense don’t seem to understand because they’re blinded by their own greed. If Bitcoin’s privacy depends on centralized run services that result in their founders being jailed, it has failed in providing privacy. The answer is doing it at the protocol level, which must be done after Bitcoin has already been accepted into the existing financial system like a Trojan horse.
People willing to put a target on Bitcoin, this forum, and their own backs by promoting centralized money laundering services for money aren’t doing some great thing for privacy. Them using everything in their power to silence and discredit those that point this out is a whole other issue. One that a strong leader would address.
