As all of you have noticed, this site have a quite high return of investment with a very short period of time, whilst it have a very low amount of traffic and transaction. As the database of CasinoBit.net is kinda public, I have calculated the transaction sum in the past 24 hours, ~250BTC. Thus the raked amount is 7.42BTC (2.9% for European Roulette)
That's fail by the way, this isn't poker. Profit could be considerably higher or lower.
