Greedy is hard to solved.
That's greed, not greedy.
I mean we must really have to control ourself first and sometime when it is come, even we already win a lot we still want to play again and again to make more money.
It requires discipline to ensure control in the game, it's a very risky game and we will be facing a higher risk without discipline.
Unable to control ourselves will lead to unexpected loses, and that makes gambling is bad for you.
