I never saw a person who got rich through gambling but I have seen a lot of people who have lost their everything through gambling.
I think gambling would not be a platform to become rich.
Yes indeed this topic is rather funny. Being rich from gambling is a matter of impossible. Maybe someone can get rich from gambling, but the chances are too small. But to be miserable from gambling is a very easy thing. Throwing everything away from gambling is the easiest thing to do lol.
Having your own casino requires a big capital. If you don't have that big capital and marketing plan, better just invest first on reputable casino that accept investors.
