The US puts tremendous effort into protecting its own citizens from their own stupidity.
The US also puts tremendous effort into keeping US funds in the US.
Combine the two and you see that the US wants to make sure that if the stupid people want to throw away their money then that should happen IN the US and not in Europe.
I agree. That is what happened to China and that is why they implemented new rules and regulations to ban ICOs. We know that there are so much money lost with these scammy ICOs and their citizens does not have knowledge to asses these type of investments.
