"We will not be accepting US or Singaporean citizens as part of our RPX crowdsale, to ensure we are operating within current regulatory policies."
Sighhh... Damnit SEC!
I think it's the same for all the ICOs now, not only a few.
Any way around this? lol
I'm Italian but currently in the US (not citizen nor resident) and for example to partecipate at Stox's ICO I had to use a VPN otherwise I couldn't access to the ICO page because of the American IP.
