I cant tell what might have been the issue or how this works, but why the restrictions to US investors in DRMR STEO tokens sales? I guessed since it was a SEC approved, US Investors shouldnt be restricted from the opportunity.
I think US residents still buy these tokens, it's just not from the on going IEO. It might be dur to exchange not in US or something? I think US residents should contact project and they will let them know the way to buy these tokens.
