No because of SEC (look what happened to Telegram's TON token)
Did you see what happened with blockstack as the first ico that gets license to do the crowdsale with A+ grade? If you didn't see that and i suggest you to take a look at the news about blockstack and how it was able gaining the permission from SEC.
If I am not mistaken, they also paid millions of dollars in legal fees to do ICO with SEC permission
Not everyone can do that
