Greed is what makes most gamblers run at loss because some of them will start their gambling session with profit but they feel that it's their lucky day and let them win all the amount of money that they have lost since they started gambling. This will make them forget that gambling is a game of luck and they should be satisfied with the little profit they have already.
They will continue gambling and before they know it, they have lost both their profit and their capital. You didn't gamble only once before losing all those money to the casino why do you feel that you can win back all your losses once in a session. Gamble within a short time and appreciate the outcome of your bet whether it's a win or a loss.
Indeed. And no doubt that many gamblers become greed especially when they win. The will to win more will come to them and that makes it difficult to stay away from the temptation of gambling. They will forget to reduce the tension after winning so they insist on continuing to play without thinking about stopping for a while.
That is a trap for those who can not control themselves in gambling. If they don't realize immediately, they may lose their money in the next rounds. No guarantee they can win more but the loss will be behind them. So it is better to be careful and always think about stopping gambling, no matter the result is.
