No one that bet with huge amount of money that has a strong heart if the person is losing. Gambling should be for those that can use little amount of money to gamble. The recommended amount to gamble with is 1% of your income. If you earn $1000 weekly, the best is to gamble with not more than $10.
It's true that no one can be relaxed if they lose or lose a large amount, especially if it's the money left over from their salary. I think it's true what you said, $10 is more than enough for gambling capital in a month or 1 week, because with financial monitoring, the level of loss and stress can be controlled.
