It's nothing new anymore where a paid shill willing to do anything to promote the competitors, like creating a fake story where there's a victim claim he has been scammed on 1xbit and he announce if 1xbit returned his money, while everyone knows if 1xbit is scam casino.
Do you think OP is here to promote Duelbits? At first, accuse them of scamming a significant amount and then say they released his withdrawal. You did not mean that, especially when wearing Duelbits signature and Avatar. I do not think Duelbits will promote their casino in such negative ways
Or maybe you want to say that either Stake or Rollbit hired him?
@OP, it does not look like you are in minus at all. It seems you have withdrawn over $2.1 Million and deposited less than that. Also, I am not clear what the support said to you. He was asking you to wait, and they will update you. Since the decision is not final yet (They did not block or freeze your account), You cannot say if they scammed you.
It might be a security check-up because you have won a lot. It is common for a casino to investigate user accounts when users win significant amounts. They want to ensure the user is not taking any unfair advantage to win. So, give them some time and wait until they finish their investigation.
