People who are making a living from sports betting is good at bankroll management and consistency on his unit bet. It's not easy though make a living from gambling.
I cannot imagine, how the gambler can make a living from gambling as we know that for winning in the gambling games, it is too difficult but I believe that there is a person that can do this but he doesn't want to show his self. it is better if we can get a job and use the small money to playing gambling and we can have a good knowledge about the sport so we can have a good chance to win the games and get the money.
