If you ever gamble and win the gambling then you will hype and get excited over limit. Since gambling always make you lose but there will be addiction + greed that overhelming human attitude. That's law nature , ofcourse they can control themself whenever they still want to keep gamble or not
I can control myself and Im a living proof of it. People are always skeptical that they cant control their urge to gamble however I do that by only playing with a small amount of bankroll. I admit that Im addicted however when I only lose a small amount each day after I play then that is not going to affect me
