It is possible, but i can`t say that this is truth with my guarantee. I saw some gamblers that don`t want KYC and they have no any problem with it. They just sure that KYC is awful and don`t want it.
I don`t know what is the real problem the OP has but it doesn`t matter - there is ToS and he agreed with it, so he has to obey it.
Actually, it is highly unlikely that he will be able to do much with his account if he will not comply with the KYC procedure. We cannot know why the OP has been requested for KYC but the possibility of him violating their TOS very likely.
Yes, there's a lot of high rollers out there that has not been requested for KYC mainly because they have not violated any of the TOS of Duelbits.
The standard practice is to ask KYC before first withdrawal. I had to KYC several times with this reason. Honestly, i don`t remember any casino or exchange, that asked me KYC in other situations. May be someone can withdraw without KYC but i didn`t. The same situation has the OP but he want to withdraw his money without KYC. I don`t think that Duelbits will change their opinion due to this thread, so i think that you`re right - the OP has to KYC or to forget about his money.
