AS written in white paper, users will be allowed to buy tokens with fiat and digital currencies. On which exchanges STF will be listed? And how I could buy tokens with my card?
I also read that the United States was not allowed to participate on the website. I think that could be a problem if you bought and then they ever decided enforce that clause.
Unfortunately, American citizens are not allowed to participate in ICO.
But at your own risk you can do ICO with foreign IP or get an ICO coin when it hits exchanges - its safer way
