The advantage is that, without prior deposit, you can check how the casino works and which games you like the best, plus, once certain wagering requirements have been met, any winnings can be cashed out. Obviously, you can't just collect the cash and withdraw it, but what you can do is use the funds of free bets at the casino. Of course, in some cases, additional actions may be required, for example, you may be asked to send an email to provided email address, but usually, following the above instruction is a way to receive the bonus. It's that simple, and once registration is complete, you will get a message welcoming you to the casinos, and letting you know that the money has been credited to your new account.
