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.
[1] BrewDog, Monzo, Revolut spring to mind as UK examples.
Anything else has failed miserably because the network can't handle the traffic. Of course they're promising a scaling fix Real Soon Now (see above for "plausible deniability R&D mode").

Wiring is free and instantaneous for anyone sending moderate sums. Fidelity, for example, does this.
What counts as a "moderate sum"? Last time I tried to wire money, every option I could find charged a $XX fee no matter how much I sent.
U.S. dollars; forex. Also, not all jurisdictions have accredited investor requirements. For those that do, using a token doesn’t get around them.
