When we play gambling, than it is normal that we become greedy. Because everyone play gambling to earn money and in this way, if we become greedy than sometime we win in behalf of our greediness.
That's why when you go for gambling shouldn't load a lot of money instead just load how much you can afford to lose for that session and gamble. If you do like this then no need to worry about how much you lost but you can enjoy the games. I never load more money to gambling site and always play with small amount to enjoy my time.
Is that the bottom line reason why gamblers became greedy in a long run? Perhaps, not all players/gamblers become greed once they start to play in gambling. Because I still do believed that there are some gambler played gambled just for fun and entertainment or sometimes for relaxation only. But in reality situation, controlling our emotions could be one the tools to prevent greed on gambling.
everyone will always have a different opinion ,
klf think that everyone who start to gamble they came with their greedy attitude ,
and some people like you think that greedy not always there when anyone want to try to gamble ,
honestly imho when you stake money in hoping to have your money get doubled in fast way , that time you show how greedy you are , to control it you have to control over your attitude.
