You're missing the blatant manipulation aspect. It's illegal in US investments. So, assuming that any crypto are available in the US, that any of them are owned by US customers, and that any of them considered securities, this regulation already applies and will be enforced eventually. I won't be putting myself at risk by blatantly manipulating prices, particularly on youtube, facebook live, and in slack, and on twitter. That's just shortsighted and risky.
While regulation is against my principles personally, intellectually and realistically, I am as subject to them as anyone else and won't be putting myself at risk. I am merely making others aware of the issue as well.
