It is very interesting marketing campaign from Open Money, very nice work for Dennis (If I am not wrong)
IS it Open Money project legit in the USA and you can accept investments from US citizens?
Yep, marketing campaign is reaaly outstanding and awesome. I've never come across anything like this before. Regarding US investors I don't know for sure (I am not from USA) but probably there are no limitations for participants, however we better wait for the OP answer.
Correct, there are no limitations. ICOs should accept any investments from US citizens.
