This is a typical time delay tactic from Duelbits.

You will most likely get asked for KYC next and there is a good chance your account could be closed permanently while they stand behind ToS. There have been a lot of problems with Duelbits recently, you can look at their thread: https://bitcointalk.org/index.php?topic=5279042.10680

If you can still bet however, that is a good sign, and you might get your funds released, but I would still be very careful going forward given all the problems this platform has had recently. If you can't bet and your withdrawals are stuck, 99% chance you will get banned while they time delay using KYC.
