From my observation, people are annoyed with KYC if the casino ask KYC during registration and when you withdraw the first time.
That is annoying to be honest. I think some users here have experienced that, they haven't deposited yet and they were asked to do kyc. And as for withdrawals, some are not for the first time but when they're able to win some huge amounts that they're trying to withdraw for one batch.
I only register and provide KYC to those casinos i think i will use in the long run.
Me too, I don't do kyc if I am not going to use a casino. Maybe for some tests and when I wanna have a look on how the new ones but if they ask for it, I won't do it.
