Well, actually US is not the only country in the world. There are places with zero chance to get any VC funding. I have even seen a funny acceleration program that offers $300 (three hundred bucks) for 10% of a startup (and there was a huge list of requirements the company and founders should meet). That's ridiculous. ICOs open a window of opportunities in such places. That's a pity though it is discredited by been used for scams.
