This is normal for greedy gamblers. You get more excited to bet when you’re in a winning streak, I think everyone does. The problem is, due to your overconfidence that you will consistently hit a huge amount, you tend to lose control of your funds, until you end up realizing that all your profits have turned into losses already, and you can’t do nothing about it but to regret and blame yourself, wishing you immediately cashout your winning amount. At least you learned your lesson as well.
I agree- this is a common mistake that most gamblers experience especially during the height of their emotions. They tend to be consumed by their own greed which results to them mostly losing their winnings in the process.
That is why I always recommend to my friends that if they somehow win in gambling, it is mandatory that they keep the money they initially bet upon and use the other half if they wish to gamble again. In this way, at least, even if you lost the money you just won, you are back to ground-zero as if you didn't gamble at all.
This is the life of a greedy gambler, they always regret not cashing out when they had the opportunity to do so. Greedy gamblers are the worst losers because they will see their profits but will be never enjoy it. I believe that the only money that you are able to cashout when you win is more important than the big win that you fail to cashout.
When you are in a situation where you feel you would win again, try your gut and just stay away. The most common mistakes that gamblers experience is hoping that they would win again if they bet. But in reality, the odds are in favor of the house the more you stay and gamble.
