There are no safe methods to gambling, it's best to stay away from it and not start it. You will lose more than you win if you keep on coming back.
But the topic is "Is their any safe methods to gamble?" So for me, in my opinion, just play what you can afford to lose and everything will be fine, so that even if you lose it is just okay because you just play what you can afford to lose.
But summing up all the money lost together.. Makes a big sum you wouldn't have thought you would loose. Sadly, that's how much we're losing.
