gambling always have risk, in the long run, the house edge will win over the players, this is maths, so the best way is to quit gambling 
Thanks but you might want to check again, I am betting as the house and the advantage is 1.9%, factoring that mathematically I am almost 14% at losses.
You need to check how the profit sharing is done for the investors because some casinos will have additional fees for the investors. You should be considering to diversify your investments into few other good casinos so that some one or two give you losses others will compensate in this kind of situations. In the longer run you will still make the profit because house is always going to win.
