They should be regulating pump and dumps to basically prohibit them all from being offered to US citizens, and that scamming landscape would evaporate.
They have to put scam developers of pump and dump projects who are US. citizens and live in the USA, into jails. If they can seriously do this regulations, scammers at least who live in the USA. will be more fearful of creating scam projects.
It's how they can prevent scams at the beginnings that is more effectively than letting scammers make project launches, raise funds, scam money of many people. Governments can not connect dots and try to arrest scammers after scam projects become too big and many people lost money with those projects.
I think it is clear, as it is stated in the post more regulations are coming. That means more restriction, more surveillance, more KYC nonsense, more taxes since US government has run out of money, more decentralized services being shut down and generally more crackdowns.
Governments can do all things and say they do it for benefits of citizens, but we know that the most benefited entity is government. They can get more money from it, for governmental operations and they can abuse policies for their own benefit first.
