This new measure makes me wonder a bit; players can keep on playing anonymously, old investors can still stay in the dark but new ones ( or already existing that want to raise their stack) have to verify their identity : why so? Is there any new recent legislation that requires you to verify the source of your investors from a certain date onwards or what? Why investors and not also players?
1. The casino probably has way more old customers from the early days vs recent times so it better no to bombard them with KYC immediately and make them leave the casino as soon as possible
2. They could be rolling out the KYC verification program in phases, starting with new users
3. Crypto regulations are getting tighter, Gambling regulations a like, so this was expected, similar to what you have seen with most centralized exchanges, so I don't think they have a choice if they want to keep operating.
