China to block cryptocurrency platforms that allow centralized trading

No matter what protocol and software is used, at some point, people will want to convert cryptocurrency to/from yuan. This cannot be done anonymously -- the options are face-to-face or via traditional banking system. In either case, it is pretty easy for authorities for find and arrest the relevant people.
I bet less than a hundred people arrested will be enough to scare everyone else so that all major exchanges will get closed.
I am also paying others in crypto. Sure it's niche now, but the only barrier to adoption is a bit of technology advancement and belief in the value.
How are these platforms different from a cryptocurrency exchange?
But not all exchanges are centralized. For example [1]BISQ is one of many decentralized P2P exchanges.
