The only thing they can really do is telling exchanges to drop them and they will, apart from the no shits given outliers. It'll be the least surprising development in cryptoland's history.
It'll be interesting to see how this moulds their markets.
the problem is in some people who do not know how to take advantage of good things, I believe that when people created anonymous coins it was not to commit crimes, but thanks to scammers the future will have to be dealing with documents to make KYC ( for me to have a residence document I have to go through a lot of bureaucracy in my country, even though I have been living in the same place for over 10 years ) on exchanges that take days to approve and are a headache and fear because such exchanges do not even have a physical office and there are no guarantees that they cannot sell people's documents on the black market!
