I prefer strategic gambling with amount that I can afford to lose. No gmabler become suddently rich by gmabling, let alone being billionaire. But, by running a gambling site, you can definitely be a billionaire. 
That is really true, no one become millionaire if you don't do nothing. All of us needs to become hard working. So that in the future we can face the world by our self. Because if the day comes that we became rich we are not shy to stand up by our self. Gambling cannot make us rich and we cannot be proud of it if we become rich in a gambling. Because nowadays people wants to see their hard works especially in facebook. They post all of their achievement their to become popular.
