The only thing that you need to do if you are going to gamble is just to do not spend the money that you earned in there as a profit result.
gambling must play in smart way, like when you play you must bring only enough money, and bring wise decisions, and when you are win also a lot of money save the half of the money you win .
That is the only thing that you have to do.. and maybe you can minimize the risks or the bets that you are playing, but this is pretty difficult if you are an anxious person who loves gambling.
But in a technical vision, there is no way to play it in a smart way.
