for several months the biggest win that I now get is of 0.09 BTC. My biggest victory in gambling (Craps), the more it makes me excited to be able to get a larger victory again, if need be I can get the victory once bet a 1 BTC, then if that happens I will definitely become a rich man.
Depend of the game, my biggest win is on the blackjack about 0.4. I didn`t have luck to win some big bet for now, but I hope I will soon.
