I can not control my greed in gambling, because I want all at once and more. Because of this, first I lost a lot of money 
Depends haha but most of all players are playing in short term with that greedy style coz in that you can make profit that fast with your luck on your side but if mot maybe your just loosing your money for nothing.All of us are greedy, all of us wants to earn fast in gambling and with big money. I won't deny it that I'm one of them. The reality is the truth and it will depend on how greedy you are. If you want just to earn and you are satisfied to win with small amount I think that's acceptable but if you always want big bucks, that's different.
