Privacy coins will exist as long as the people using it, but there are chances for them to get delisted from regulated exchanges but never on decentralized exchanges. Coin mixers have to run very carefully and that is what we need to understand from the sanction.
I think that all coin mixers will be banned sooner or later.. And the only way out for me is using no kyc decentralized exchanges as they seem not to be affected anyhow. Moreover, you remain anonymous there what is very important these days.
