Is there a problem with balances? I used to have about 35k satoshis just a few hours ago, now I logged in and poof, only 4k left?!?!? Checked my stats, no payments are sent or games played so that rules out my account getting hacked. What could have happened???
I don't have such issue and I haven't saw anyone else reporting similar issue. So, most likely that there is something wrong on your side. Maybe someone have access to your account and made a bet. Now I don't remember is it pending bets is shown somewhere in your account.
I suggest to change your password and set 2FA to be sure that only you will be able to login to your account.
