My 0.02Ƀ?

Prices should be in Ƀ.
Crypto should not be key-pair based.
You should work on editing Bootstraps CSS a bit more (It's SUPER bootstrapy).
If you don't plan on having a mobile app, I also suggest moving completely over to Foundation by ZURB, it's screen-size policy is far better than bootstraps fluid grid, in my opinion.


If I think of anything more, I'll let you know.

Good luck!
