First of all, I really love how simple looking the website is no to much design and also very easy to navigate around and if I'm to rate it over 10 then it would be a 7 for me. But I kind of encounter an issue I'm not sure if it's the same for all devices but mine kinda looked awkward.
Here's what I'm trying to say, the
Sign up button seemed to have been masked by the background since both of them have the same color, so it's very difficult for one to spot the button unless they hover their mouse over it or accidently click on it. I think you should try to change the color to something more conspicuous.
The part of the page that I found most interesting is the
CARD section like the pricing of the card is just something else, how on earth will you charge
0.4BTC for a verve card and 0.8BTC for a MasterCard like that's really got me thinking, if I spend up to approximately 1
BTC just to get my card then how much will I use the site to hold?
I think you should reconsider the pricing.
