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.
Yes, I do agree with it but it seems for me that bonuses will not let one enjoy in gambling as we all know that we play and get motivated through the amount of money receive through winning. If bonuses does let one to be happy in gambling and betting then good for that user.
