Actually I’m in favor to OP this time, A hacker will not login someones account and bet randomly huge bet to slot just purposely lose the balance, If I where the hacker, I will wait until the withdrawal is already cooldown then setup 2FA and withdraw the balance. This a serious case and probably a made up hacker story just to zero debt to player. I will understand if the balance was withdrawn to other wallet but since they have a max withdrawal limit, they can’t do that instead purposely lose the balance. 

@Slotella can you provide a proof that hacker atleast try to withdraw the balance?
