There is always a greed index when we win, we don't ever consider ourselves lucky at every point we win hence we become very greedy and more confident enough to be betting more and at such doing we might have losses and probably lose all the money being won while trying to chase losses, the exit door after winning is always problematic to almost all gambler, withdrawing your winning to your fiat account is another helpful way of exiting from your gambling platform in order to avoid Lossing out completely from the money you won, because if it is left there you will still be tempted to play more bet even when your emotions has been detorated.
In my opinion, when we win, it makes us more confident to be able to get more than we already got, apart from that, when we win, the temptation to continue betting will be there, especially with the initial thought being to seek profit, there will be thoughts that at that time they were lucky so they continued gambling with the winnings they had obtained, but however the risk of losing would not disappear so the casino could make the winnings they got disappear again and not one or two incidents like this have happened in my opinion. This incident happened again because they made the wrong decision.
winning is actually not difficult, it's just our own thoughts and desires that complicate everything. If we gamble and manage to get a win and then withdraw it without thinking, then everything is not complicated. However, when many gamblers win, they complicate things by following their desire for more, but that only makes them experience problems which sometimes makes them even more disappointed.
