i dont believe with safe methods at gambling
it is pure of lucky, with the best methods if that time we lose, we will lose
gambling is risky activity
because there arent any safe methods of gambling, to be honest in my opinion it is better to not gamble if you are too scared to lose money
People who are working hard to earn money will never prefer to invest their money in gambling as they know the value of money and loosing that hard earned money is gambling is the worst thing.
