This is not a sportsbook. This is a betting exchange. Betfair for the bitcoin community.

If you don't understand what a betting exchange is and aren't willing to put the time to learn that's fine.
If you want to give advice on how to make the interface better, while refusing to even learn what the concept is - that's trolling.

Imagine you did not know what bitcoin is, then went on forums and said "bitcoin thats way too complicated, will never catch on, Im not willing to learn how to use it or what it is!  You should make it better by hosting it on one single server in Panama and make it exactly the same value as the dollar to avoid crazy fluctuation!"
