To be honest I have been using the same login details for a few bitcoin sportbooks for a lot of time and it happened only on stake.com.
It's strange for me that it happened a few minutes after I placed my bet and that this situation has not happened on another sportbooks where I uses the same login details.
Same login details everywhere? I advise you to drop whatever you are doing and enable 2FA for all your accounts asap since the hacker could easily gain access to your other accounts in a similar fashion. Stop making it easy for him.
So there is no change to get TRX refund? Even this low amount of TRX?
I doubt they will refund you since your balance was used up playing their games even though it was technically not you due to a security issue on your end. Be happy that it was a small amount and make sure to enable 2FA in the future.
