Good thing is that casino managed to react quickly, notice that they got hacked and have started investigation. Only few days have passed since they got hacked and problems seems to be solved. Either that hacker wasnt really smart, or it was a kind of a black promotion. There were no actual hack, but casino gained some popularity last days. The other thing is, that we dont know what kind of account or accounts that hacker had on CEX. Account made with real KYC or used fake one. What I think is that Metawin have failed with their account or access securities, and someone managed to get access by accident, that is why he has moved funds to CEX.
