I would like to inform everyone that Bitsler is not as trustworthy as it is presented here.
They are very trusted here and even outside Bitcointalk because they have many years of operations with good reputation.
I managed to win about a thousand euros on sports bets. When I wanted to withdraw my money, the transaction did not go through. It has been in "on hold" status for three weeks. They answer my questions "we are investigating, you still have to wait".
Please note that my bets were only on the most prestigious world sports events and my account is fully verified (ID, address verification documents). There is not the slightest reason to investigate.
It means you won big and submitted a big withdrawal. In all casinos, they will notice your account more when you hit a big win or some consecutive big win, then submit big withdrawal(s).
If they put your case "On hold" and are investigating it, it's not a good signal at all.
I am considering legal action.
I believe a big casino does not know legal action risk and they don't arbitrarily pull out their investigation card against your account if they did not detect something suspicious from which they decided to investigate more deeply about your account.
Meanwhile, you can wait because Bitsler team did not announce you with a final result of their investigation.
