Hi, I emailed customer support, this is what they said:
Thank you for your feedback! Our platform is still in beta, and we are constantly trying to improve the user experience. I will relay your message back to our team for consideration for the next update. I've taken a look at your account and noticed that you are currently residing in the United States. Unfortunately for U.S. customers, the funding option is not yet available and the only option to purchase cryptocurrency through us will be through credit card.
So in summary U.S. users can only pay the 7.5% fees. Maybe they will expand and lower the bank transfer fees. I really liked the interface though. :-P
Interesting! That's not even what the press releases said, or what was communicated so it sounds like getting a follow up finalization on all this stuff would be much better. That's kind of a big change and would necessitate a big ol' video edit.
