There was a guy named wang tang or something on bustabit that played with 100k+ bets each time and made over 6 million dollars or something like that, or maybe it was 600k I am not sure, however I remember clearly that dude was gambling on huuuuuge bets and he was making a great return for it as well, he was just getting out very quickly but 10% of 600k is still 60k, so even when he got out quickly he made a ton of profit.

He kept this up for few weeks I suppose and made an insane amount of profit, everyone was talking about how dude was bankrupting the investors with how much he was winning. You know what happened? Dude ended up losing all of his profits plus some more money on top of that as well. Never bet against the house, even if someone has 7+ digit profits, it still doesn't mean anything as long as they do not quit and leave, if someone keeps gambling eventually house will win, there is no possibility that house won't, only way a gambler could win is if he leaves when in profit.
