I'll acknowledge that the domain argument is not very powerful, however it is clear that my concern is not unwarranted. It is very improbable for a casino to receive 1.2M bitcoins wagered and still tread far below their expected profit.
Not improbable when one guy does single bets that high (100-500 btc a go). As I wrote in the other thread, many players had doubled/tripled or even more small bankrolls, eventually losing. Not so surprising for a guy with a 10k+ bankroll to win 8k (80%).
It's like winning 8 btc starting with 10, doing 0.1-0.5 btc single bets. Not unlikely at all, seen it hundreds of times.
