last time I made deposit and withdraw on Bc last week before update, they not ask me yet for any KYCI logged into my BC Games account and I was able to deposit/play - didn't try to withdraw though. I wasn't forced to submit verification docs, just incentivized with 15 dollars worth of bonus funds.
And just FYI, the way it works in Curacao; there are four Master License holders who then allow companies like Goldenbet and Metaspins to "sub-license" - so there is no casino with a "Master License" so to speak. But you are correct that some Curacao-licensed casinos have started to update their terms and conditions to explicitly mention they don't take UK players.
Laughable, really, though, as any casino in Curacao has NEVER been allowed to take UK players. They should have always stated that in their terms and conditions.
