It is ironic. People from the states have to wait for these tokens to be listed, and they buy it at a higher USD value. I think its going to take some time for cryptocurrency and its use in US and some other countries to be regulated.
Well right now a lot is going on in the sphere and I believe the regulations needed yo ensure fairness is not fully implemented so we are going to see a lot of this stuffs
I think it's fine even if US people have to wait for tokens to get listed. There are many hurdles/restrictions due to last couple of years experience with ICOs. So US will not give approval easily for IEO participation
