True, it will be become wrong if your family became affected in your addiction in gambling. But once you know how to manage money and your self and you know how to control your greediness. I think there will be no problem at all.
How would you control yourself if you start losing all your money,addiction is a real problem,you will be addicted automatically,you will win in the beggining and those small winnings will tempt you to wage more and then you will a lose big amount and after that you will try to recover the loss and that is when gambling turns from entertainment to a problem.
Not all people get addicted, many people understand that gambling is entertainment and not a method to earn money, so they don't chase profit and don't wager more than they can afford to lose.
