Even though it's an uncomfortable thing to lose some amounts of money being deposited into a casino there's still a level of confidence one might have when you know that you are gambling with your own money, borrowing money to gamble puts us in a bad state just like you said especially when we end up losing the money we staked...this is one of the biggest mistake that anyone can ever make
You can feel confident if you lose the money you were ready to lose, if you lose more than you wanted then it's bad, but if it comes to losing credit money then it's a disaster and such a player definitely needs outside help. I wouldn't even bet credit money, even if I got some kind of forecast from an insider, because anything can happen and losing money that doesn't belong to me is too reckless.
