Yes I agree with ethereumhunter about this "If gamblers seems aren't ready to stop after losing, that will be their risks and they can lose more money" we need to control our limit in gambling do a budget like I have said earlier never chase a losses because the winrate to choose a losses is razor thin and besides that I usually gamble for fun wining from it just a bonuses.
Exactly what you said. Controlling our limit in gambling is a must so we can prevent any problem that can occurs because many people already have that problem. We must learn from their experience and avoid it not to happens to us.
Never chase the win or lose because that will cost you more money that you can imagine. We will only need to playing gambling moderately by always limiting our money and time so we will not staying at the casino too long. Many examples that we already see that can be our lesson to avoids the problems.
Reality wise, when you start chasing your losses your control over your gambling activities got dominated by your emotions, it's a instinct inside you that push you to keep trying to recover, instead of taking the rest and quitting out from the gambling house, you'll see yourself adding additional money inside your bankroll, hoping and thinking that by luck you'll be able to make something decent or you may recover those amount.
Most of the time, the outcome always in favor of the house they manage to manipulate your emotion to keep you from that kind of thinking and let you chase your losses as they understand that emotion will lead you to failed.
Meaning that they will make more money as you keep failing from controlling yourself and you keep bringing more for them.
