What was the latest update of this topic? does the OP managed to submit his KYC or did he get his winnings? All gambling sites have a reason why they should hold or confiscate the winnings and if they don't give a valid reason then they just destroy their reputation.
The ops have not updated the thread for a while now, and with recent discovery about the casino KYC rule, it shows that they have it covered in the casino terms and conditions that KYC is mandatory for the first withdrawal of any amount, which is strange anyways since most KYC casinos allow players to withdraw small amount without the need for KYC unless the amount exceeds the limited set amount, most casinos set $5,000+ as their baseline for KYC verification process.
