Based on the bet history, most bets that are higher than 100 bits were lost bets. I did not check all pages of the bets history but I can see some 10,000 bits losing bets. Shouldn't you make some profit from those 10,000 bits losing bets? That's even 3x bigger than your bankroll.
If anything, the majority of those bits would be going to the
bankroll, not his pocket - Only house edge profits (they are usually subtracted from the total bet whether it's a win or a loss) can be pocketed by the house.
So that would make to be several hundred bits at the highest.
