If you want to raise money by selling stock to non-Americans, there are European crowdfunding platforms that let you do exactly that. Real companies with actual products[1] have raised millions on these platforms, whereas every ICO ever is stuck in "plausible deniability R&D mode" where they pretend to be implementing their magic-powered whitepaper but nobody actually uses any of the stuff.
