A lot of people have a gambling problem these days but its also logical because gambling can be highly addicting like a game.
Most likely this is because of the feeling you have won and you want that again without knowing it you can addicted to it.
Overall I'm thinking self control will help the most people.
Yes, gambling addiction is the main root cause for the problems of many gamblers here. Being over ambitious towards winning big profit from gambling causes gambling addictions which eventually results in big losses.
