It's great that they also allow US investors. Not many projects lately allowed this.
Woah, hold it! They are still checking, nothing is not settled yet. If UTrust tokens are considered securities it is a no-go for US investors. There is also a chance UTrust raises a red flag in the US because of "activities that relate to transactions that involve currency exchanges or check cashing businesses". Then again there are also crypto exchanges in the US like Bittrex and Kraken.
These tokens can't be considered securities, not so far anyway. I think I remember that the dev's made some research into this.
