#CryptoCurrency question for people smarter than me. 

What must happen or get approved so that US Citizens can "legally" participate in ICO/IDO/IEO?

I have been in since 2017 and I have probably missed out on MILLIONS because I was not able to join these ICOs 

(Yes, I know the other ways to do it, but I never felt comfortable taking those chances with money and govnt)
