I think that can be clarified for sure.
I am not familiar with the conditions for the bonus. But its okay if I receive the bonus after a deposit and then play away my deposited money although I have not yet unlocked the complete bonus amount.
I have collected bonus amounts myself for two times and not unlocked then.



But basically, it is a problem if you deposit money and then withdraw it again directly. But in my opinion, this has nothing to do with bonus abuse but with money laundering. Casinos are not coin mixers.
