Not easy, when we're emotions then everything will be hard to be controlled, I never experienced it seihngga makes about 3 btc lost in just over 5 hours. self control is very important so that we will not lose.
It is one of the most important things while gambling. If we dont have any self-control we should not gamble in the first place.
I have seen many people win big then gamble it like anything without any control ending up losing all. End of the day that addiction is what the owners want because in casino games you are bound to lose if you keep on playing. So in reality the owners want you to keep playing so you lose all that won and deposit again.
I could testify that what you are telling is true, not all of us can easily control ourselves especially when we keep winning and we feel this will be a good chance to get more money and we push our luck so hard. Mostly based on experienced I lose my entire winnings including the bankroll, that experience help me realize that greediness has no room in gambling if we want to success, it should be done slowly but steady.
