I read that and Betcoin.ag is the best online all around bitcoin casino and they do offer betback, lossback and rakeback.  There are over 50 participants in their signature program and I see more and more people want to join. 

Don't get caught up in the trolls.  The more popular a site gets the more trolls they get.  Meanwhile I see more new players and activity at Betcoin.ag everyday.  I should also add that I enjoy NitrogenSports and used to play at Seals but still play at ACR from time to time.
