I'm speechless, he's able to recover his 50BTC loss and having a net profit of 100BTC. That's enormous considering the price of bitcoin today.
It definitely is, yes. And I'm personally very happy about it, especially because he registered here and gave some details about his wins/losses and his playing style.
But you also have to remember: the BTC he plays with here are probably only a small part of his portfolio, I don't assume that he uses all his BTC for gambling. And that in relation is actually what should make us speechless
