Can we just discuss the market size
Another one is what I come across last week which is a new casino and their stats on wagering amount really made me surprised:

Look into the date when this casino was announced here and the total amounts in bet. There must be at least house edge as sure shot profits which may sum in millions.
Windice is another new casino which is achieving 10 million bets consistently for every 10 to 15 days. By considering its age on this crypto gambling industry and its competition against primedice and bitsler, I am really wondering on the market size of this crypto gambling space.
215k BTC in 5 years is a crazy number. So assuming that the casino mainly used bitcoins lost by other gamblers - a loss of $10m doesn't seem so bit anymore as others must have lost many more millions on that site. But then again it's just an aggregate over a long period of time. I would assume that most people just gamble for a few hundred bucks.
