Usually when your future was changed, I really do think that everything will also be changing. But anyway, to be realistic and we get rich, I really don't see a poor man going to gambling site again to make a profit. Usually if you are from a poor family and you make a fortune in the future, you will treasure it and most probably you take good care of it and never carelessly use it on things that you know you will regret in the future.
Probably if I get rich and I am a gambler, I would go with investing on the gambling site and not betting. I want an easy life with no more risking a lot and wasting my time.
