He is not talking about that. I think he invested almost close to 100 BTC in the site, he didn't gamble with it.
What is going on with the site is very fishy like he mentioned before, some new players are winning over 600 BTC like that Underdog guy, Look at his stats.
I would be careful because this looks like another case of "Willy" bot like with Mt GOx. Basically he bets and losses but since he has unlimited income he can keep martingaling until he wins.
no one has unlimited income, unless you mean there's some exploit where he can bet any number no matter how high. Martingaling isn't a winning strategy even with 100 billion dollars.
what's really fishy about the site is they robbed me and at least 2 other high balance investors.
