It's also possible that the hacker already knew your account before you logged in recently. If the hacker didn't withdraw the funds then I assume 2fa is activated on your account? Or if it's not yet activated the hacker probably thought that it'll notify your email when making any withdraw so he just bet your funds away.
There's a minimum withdrawal threshold. I see that 47 $0.04 Tron bets were placed at a 0.03% win chance. Maybe someone got on your account and could not withdraw and was just trying to win it big and then remove funds. I can send you a list of IP's that accessed your account if that helps but my guess is unless you were running a script or bot then someone got on your account.
My first suggestion is changing your password and if you have any other info we can explore this further. Also I highly recommend using 2FA, anyone who says they have never gotten hacked but doesn't use 2FA is just waiting for it to happen.
There's simply no way our system can just arbitrarily place 47 bets, it has never happened before and we've done 70 billion+ bets between both our websites so the above is my best guess.
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.
