Agreed, it was very stupid to take all the wealth in gambling, he had lost control could not set betting limits and he was gambling following the flow of emotions because he had lost a lot of money and he wanted all the losses to be recovered in one bet. He didn't think about the risk of the next loss, as a result he has lost all the money he has and we don't know what his fate will be now, maybe he is experiencing depression and stress. We have been reminded in various threads to gamble by setting limits and gambling responsibly so that you don't experience high losses and you can enjoy gambling without getting emotional and addicted.
People who are controlled by their own emotions will find it difficult to stop gambling before their money is completely gone because such people usually forget the risks of losing and losing in one bet so it will be difficult to give advice to such people. Unless he really has the intention to stop on his own without anyone telling him to stop before all his money runs out, but that is always difficult to happen. Because people who are controlled by their own emotions will always make decisions hastily without considering any risks that could occur in their decisions.
Because there is a sense of curiosity if the money has not run out he may believe the last money can bring good luck then this will be discouraged in the emotions he brings in gambling, this is not a few many gamblers take this step in the hope of changing his fate or want to win.
Gambling discipline must have limits, manage risks, be responsible and other factors that make you gamble not at great risk in the sense that we can limit it to what has been set.
If the bankroll is depleted enough stop...
Someday the money will be there again and we can still play with self-determined limits.
