I'm not too greedy, maybe. Indeed not everyday i gamble. Even when i have gained profit 5% i'll soon leave casino.
It is a very simple logic, you withdraw the profits that you have when you thought that you have enough already, being greedy won't help you to win bigger, it would be better if you are going to make profits from time to time, which is safe, unlike if you are going to be greedy and continue to gamble with your profits and the chances of losing is very high.
There no need to question what will be the result of being to greedy ,The result will be lose or you will lose all the money and profits you make if you don't stop as early when you already gain some amount. Be contented and when you already make money quit so that you can stay away from your emotions .
