It is a concept that is quite good. Unfortunately, it is not always we always get. Gambling system because it is not the same as what we do, the more we want to benefit the small we get it and vice versa
having greedy can make us lost everything in gambling and its a big problem that every gamblers or everybody have inside us. but well its depend on ourselves, want to control it or not.
Yes play with no greed is already included a smarter way to play gambling I think. because you are smart to control yourself if you can do that, in order to avoid losses, when you've got a considerable profit.
I agree with it play without greed so that you are going to be relaxed while you are going to gamble and that's a smart way on playing gambling.
And if ever you are going to win already just manage to quit already so that you are going to be smart with your winnings and you are not just going to get lose again by the house.
