We have some interesting examples here on the forum as well. When a casino gets big enough looks like they need to implement mandatory KYC. It seems they can't operate at a high level without following some rules & regulations.

There are many interesting things waiting for us, the crypto world is a very exciting place. I believe that in the future many crypto services (including casinos) will have mandatory KYC. But I also believe that there will be crypto services that will remain true to the original crypto ideology and will not have mandatory KYC.
