I really don't like KYC for gambling sites nor I support it by any means.
I either don't like KYC for gambling, this thing don't coordinate my habit thus I quit gambling. I am not commonly happy with KYC on any gambling platform, it should be demolished. It makes things complicated sometimes so its been great discover alternative rather been struggling.
whether they really aks KYC for withdrawing or just for "suspicious" account?
why they do not require KYC after registration and before first deposit, it will be more clear. Also, submitting KYC at the end it is not certain that this is the first owner of the account.
