No bets for almost all the events, I think you need to advertise this site a lot because there is next to no activity currently, which usually is the case with BTC PVP sites.
I found a simple solution which can help increase number of players. All they have to do is announce that finding a bug/exploit/error on the site will be backed by monetary gratification.
I am sure that after that there will be a lot people willing to test the site.
