What happened with the USA members? I see that a lot of exchanges prohibit US people trade nowdays (for example few days ago Bittrex did this too..), now I see that Bancor follow this...
In light of increased regulatory uncertainty, we believe that restricting US-based users from executing conversions via our web interface is the most judicious decision for all members of Bancor's ecosystem at this time. US citizens, domiciliaries or users from US IPs will no longer be able to use Bancors web application,
http://bancor.network , to convert tokens. Users can still access, hold, and transfer tokens. Read more here:
