If ever that Duelbits cant really be able to retrived it out then it would really be that an expensive lesson learned for OP which its
always been that recommendable that whenever you do tend to deposit thousands of $$$ then always double check out those warnings
because if they have stated that wrong deposits would be lost forever then there's nothing you can do.
OP can get his funds back if Duelbits wants, the whole thing depends on Duelbits. Since the Op made a mistake here, he will have to wait until they give an update on this. Duelbits forum rep has been offline for a month, now when he comes online he can update this thread on the current situation. It is true that if the OP does not get these funds back, it will be a very expensive lesson for him so that he does not make such mistakes in the future. But I hope Duelbits will try their best to return the OP's funds.
