I also think this no KYC era is slowly starting to disappear, which makes sense when looking at how much stricter government regulation is getting.
Governments have been doing this faster than what I thought but likely you thought the same too. From AML, KYC (but not too mandatory, and enforcement was not too strict), now AML and KYC everywhere, then we have MiCA and likely more in the future.
I really agree that even if a casino does not require KYC or advertises itself as no KYC, that does not mean users are fully free from it. Casinos still have rules, either their own internal rules or pressure from outside regulation. I have personally seen a few casinos change from no KYC to KYC, so it should not be a surprise if someone gets asked for it someday too, and sooner or later the no KYC claim from a casino will likely fade away.
First, it can be their buzzle words for advertisement, saying no KYC while there are terms and sections for KYC in their ToS.
Second, from centralized exchanges to casinos, KYC is always dangerous and useless, and it has been repeatedly warned many times and everywhere.
Why KYC is extremely dangerous – and useless.Centralized services frequently locking people out of their accounts and demanding KYC.
