These kind of bonus are encouraging for the new gamblers but if you will do a deeper research and you will have more experience about it, you'll be pissed off somehow on how they will change and won't agree with the terms they made. This happens when someone wants to take that bonus, they will give you a reasoning that you need to pass some of their requirements just for you to become eligible with that bonus. Having a bonus on your first deposit, can't be considered as win.
