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.
The fact that investors from USA have to wait for the project to get listed before they can purchase some tokens has some positive implications to the project and the cryptocurrency space in general. Due to the volatility of the market, it may be out of place to say that the tokens would be purchased at a higher value after listing, reverse could also be the case.
