Why everybody bother so much? That guy who is playing and risking all that money is not the first and will not be the last. Everybody plays according to their own potential. He probably seems to have nothing to lose and therefore does not care about losing all that stake.
Lol I agree there is nothing to be bothered here and try to analyze the bet result. Actually the guy does not lost any amount of BTC but gained 45 BTC.

Edit : 10/12/16
Analysis:
Total wagered (including loss bet): 438.19021 BTC
Total win: 261.1699 BTC
Total loss: 216 BTC
Net gain : 45.1699 BTC
So I guess there is nothing to be bothered here. A rich guy playing in a Casino trying his luck to earn more Bitcoin and he successfully get it by booking an overall Net gain of 45.1699 BTC
