and they want to chase their loses.
It's not because they just want to chase their loses. Those people who won big before like to experience it again so they will try to play over their limits. Others also don't want to cut their winning streak since why should they stopped if they are lucky.
That's a common situation already in gambling and even those professional ones are having a traits like that. For me, it's ok to play on limits as long as after doing gambling, they are in still on themselves without any changed towards their attitude.
That's another scenario, what I explain is if someone loses and loss control, they might chase their loses because they want to win back, and once a gambler loses control, he or she will never stop gambling until he win or he loss everything.
That's the big risk in gambling but actually we can't blame it to the gambling site or the gambling itself, but ourselves, we are in control, so we have to be responsible.
Gambling is not a ponzi scheme or something that guarantees winnning, so let us not expect that we will win everytime.. yeah, some came back to gamble, but they have to also accept loses and understand it's part of the game.
