Of course, it's unpleasant when the casino delays withdrawal for such reasons. However, it's worth noting that many gambling sites write all rules on their ToS page include terms of withdrawal. So any gambler should take a few minutes to read ToS before starting to play. At least it will avoid misunderstandings if the casino suddenly asks KYC.
It is not about having that on ToS or not, it is about the fact that they only specifically do it to people who win a lot. I mean this is not even just the case for betfury only, it is the case for nearly every single place. We only have places that either ask beforehand or ask it after you win big, there is rarely any good places left that doesn't ask it at all. Which is why I honestly believe that there is a good case to be made for KYC to be asked beforehand if they are going to ask about it later on anyway.
What is the point of not asking it, if you are going to end up asking it anyway, what do they want, to surprise us? I mean this is not a birthday, you are not going to suddenly come behind the couch and yell surprise!! This is a casino, leaving it to shock factor makes zero sense to me. Either not ask it at all, or ask it beforehand. That's just what I feel about it, maybe people could disagree with me.
Hahaha, not a party that will let us enjoy with the surprise
But kidding aside, there are many cases that happened the same thing from what you are saying, there are cases that even the site who's not requiring any KYC but once you win a huge amount, they will require you to process and provide your KYC, not good for high rollers who don't want to reveal their identities.
It's tough to accept that in order to withdraw your money, it will be frozen for a while until you complete your KYC and justified all those
concern coming from the gambling house.
