I created a site with similar idea back in 2008 (even tried to get into y-combinator, but no luck). My big stumbling block (among many things) was that I couldn't let people cash out with out a lot of paperwork. Basically either be a bank or create 1099's for everyone. Don't you have "Know your customer" issues or does using cryptocurrency make that go away. I would not think so. May you will just worry about that later, when/if you get traction.

How about nested comments?

Looks great so far. Good luck.
