I do gambling but I don't feel any stress, because I just gamble the amount that I can afford to lose. It is stressful if you use all your money/bitcoin and then you lose all of that. yes that is stressful but it is depend on how much you've loose.
Same for me !! but there are majority of the people who play gambling with greed of money and bet their all money and try to bet higher amount because they want to win more and more bitcoins. But greediness lead you to loose all your bitcoins. So bet always lower amount and the amount that you can or you will afford to loose.
