I think some members here are conflating your lack of elaborating with you treating the OP unfairly. From experience in posting in many scam allegation threads I am fairly confident Duelbits must have good reason to payout all that money to the OP and then refuse to payout the final request.
From what I can see, it also looks as like the OP has not met the request to provide further information. If the OP has supplied a few Etherscan links and not much else then maybe he should gather together some more of the evidence you are requesting. Have you made it clear specifically what you are looking for him to send you (other than transactions that align with your records)?
