I tried withdraw 317$ about 8M Vietnamdong. And they didnt approve it. They required KYC my account. I sent documents to them for KYC.
After 30 minutes they blocked my account and stolen all my money.
So basically they didn't approve your KYC*.
See, I'm correct again... Failing KYC means being instantly banned in every casino I know, so it's not new.
Determining whether the ID used in the KYC process is fake or not is outside my expertise, so I won't dig into it further.
Anyway, to avoid this issue, users can try to get verified BEFORE depositing a significant amount of money. That's what I did in the past. I made sure my account was clean and eligible, and then I played -- not the other way around. You never know if your ID has already been used by a hacker or whatever. If you use a fake ID or Photoshop your photo, man, it will get caught easily.
Nowadays, I rarely deposit big amounts and only play for fun, so I don't bother with KYC.
