So my question is this,as a gambler what mistake have you made when gambling that prevented you from winning big.
Let's discuss.
Believe me, what you tell in your experience. also, is our experience. in fact, it's not rare that we miss that opportunity many times. However, I don't have a precise answer to your question. because, it all depends on how you interpret gambling for yourself. for me, what you tell in this thread is not wrong. it's not a matter of greed or anything, it's a matter of how you believe or not with the bet you make.
If you were lucky with that gamble, I'm sure you wouldn't say it was greed. but because what happened was the opposite, it seems you feel regret with the bet you made. remember, in betting, winning and losing is part of the risk and that is commonplace. in fact, i have as much experience as you said.
As a tip, if you bet again, and do the same betting pattern. say, you are just waiting for one more game to win. then, the casino offers a back offer. sure, you can do something. Well, you did the research again for the last game. also, you can look for various references to strengthen what you have chosen. If you find that there are changes, you can stop betting and get the money offered by the casino instead. point, no need to be discouraged. you can still get another win, another time.
