You have a valid point and that is why Duelbits should post here providing some information that would be deemed satisfactory to the majority of those participating in this thread.
In my view, the idea that Duelbits could scam the OP is as preposterous as they come because Duelbits are not scammers but the way they have handled this allegation is sub-standard. It has raised questions if they have allowed withdrawal of that much money (4x $500,000) and then blocking the 5th request without providing the OP with a clear indication of what their investigation team allegedly found and without asking him for details regarding a specific transaction or deposit.
It does have to be said though, Duelbits have not come out of this situation looking good at all when they could have (and probably should have) at least made a public statement that would have provided a better explanation. They have asked for further information in the 15th June 2023 email, the OP has not sent it and Duelbits have not sent another therefore the situation is at a stalemate.
What more (specifically) do Duelbits want from the OP?
Amazing how you can say so much without saying anything.
How can someone show endless transactions? What if he doesn't use an old wallet anymore? Also, why does duelbits even want to see all of these, for what reason? And why now, after withdrawing much more before? Makes 0 sense and doesn't look good in my opinion.
Of course they can just refer to the TOS, as usual. But tell us, why? Why is OP being targeted even though he didn't violate any rules? There are no allegations of multi accounting, arbitrage betting or other nonsense casinos come up with so they don't have to pay.
