Some people here have not understood the topic the OP has actually posted. Gambling your money is one thing and investing in a casino bankroll is different. While gambling will be a loss in the long run, investing in the casino bankroll is not so. However you should also be ready to lose some if some high roller wins a lot since you have a share of the casino bankroll. However investing a small amount is not bad and is worth doing in reputed casino site - recommend you do research about it before doing it.
