It's good to play gambling with sign up bonuses, but I don't think I can sustain long with it without losses. You need to experience failure first in gambling in order to win at the first place. By the time you'll be mature enough through experience, gambling management is your own way to become lucky to win the betting games.
It would not last long and you would have to either stop if you can control your emotions else would have to put more money in order to continue further . Unless you the luckiest person where you can make money form that bonuses you can play further.
