Experience it so many times even manage to double, triple or even more my capital, but ends up losing.
The problem is our greed, no matter how much we win if we couldn't control our greed we would just lose it all.
When you make a deposit, then bet, get a big multiplier and then use that money to get more wins, then you are digging your own grave. Greed in gambling is very dangerous. I think it is important for every gambler to get the mindset that in gambling no matter how many spins and bets you play especially in a casino or slot, in the end the house will win. A gambler's victory is when they decide to stop gambling. The casino does not force you to gamble and does not prohibit you. That is your own risk as an adult.
Greediness will make you forget the reality that you will have difficulty winning in gambling. We may use more money, more than the deposit money because we want to win more money. But if we win in one round and realize that the next rounds will not be better than the last, we will stop gambling and will not try to win more. We can control our greed and say that the last win is enough for us. We know that the house will win much more than us so we will not risk more money instead just stop gambling. We take responsibility for our money so we need to be careful spend the money.
