This should be the most reliable stop for the exact stats:

Wow, thanks, I've never seen this one, I'll try to figure out my thought using it.
Never thought of that, because there are sites that I know but I never know how much profit are they getting every month or week. Why not ask them, PM the owner and tell him that you have an interest doing some investments and ask if how much are they getting, though i think it will be rude. But the point is, you are investing so you can get profit so you are just being careful about it, so just ask them.
Most online casinos publish their win/losses as far as I know.
The reason they are collecting investments, is to make sure that they have a big enough bankroll to pay in case someone wins big. Without the investors, they wouldn't have the liquidity required. Basically, the investors carry most of the risk for the casino, which is worth a big chunk of the profits for the casino.
Yes, win/losses can be seen mostly but there are to many bets per day and no statistics on months and stuff. Investors carry the risk? In which way? I mean, if casino is able to pay the person, my stake is still mine and I get the money from the general profit, right?
