Your comments have been noted and we agree to disagree because I am saying my assumption is correct

Keeping aside our differences of opinion related to this matter, what do you think the OP should do next in order to try have access to the funds he claims were scammed. Apart from proceeding via a legal channel what else would you suggest and do you think he should appoint a lawyer to represent him?
Im not saying Duelbit acammed or not but im saying your ssumation and logic are very wrong
I get your point, and I agree that the only thing OP can do is pursue this matter through legal action.
But what other people asking here is 'What could DuelBits do better in this matter?' your previous post seems to imply that DuelBit shouldn't be 'punish' for what they've done to the OP, and they are not obligated to do more effort to find the best way to solve the problem.
I am not saying that the OP is 100% right and DuelBits is scamming, OP has sent step-by-step the details on how he acquire the fund he use to gamble, but seems like nothing is right, and theres no details on what is wrong, only shallow explanation that it's not align with their system.
The next question would be what would the other gamble do? should they keep depositing money to the site while they know Duelbits could do the same to them as they do the the OP.
