For me in my opinion I think gambling well never be a profitable in the long term, especially sometimes we go greedy and go for another spin. We live in reality not in movies, even if you have rules in yourself or discipline your self not to over board, there are always time that your going to exceed go for it. I have more trust on investing than gambling if you are talking in long term profit. In investing your money you can see how much will you and you can invest in different places, than gambling you can lose you savings or money in an instant its just like giving away money. That's why I prefer investing than gambling.
