I really don't get it. Windice has an house edge of 1%. If someone wagers 14 BTC to win 0.1 BTC (price for the first place) he statistically has lost 0.14 BTC during the contest. So wagering that many BTC has no sense in my opinion except "look guys how big my pockets are" ... or do I miss something?
This is gambling. Most of the people lose their money and it's normal.
I don't know whether that user has lost 0.14 BTC or not. Might have lost more and might have won some BTC. Even if they is no contest, there are many people gamble. From your point view, no one should gamble.
