The management of any casino or bookmaker is now always faced with a rather difficult and difficult choice - either to introduce a mandatory KYC procedure, and, accordingly, lose some of the players, those players who are important to remain anonymous, and lose some of the profits from their game. 
Or take a chance and keep this category of players, and possibly get trouble and problems from government regulators.  All the same, most of the casinos prefer not to take risks and strictly comply with the laws.  But still, the mass of players who do not want to reveal their identity should be able to play.
 And casinos without KYC will still exist and new such casinos will appear in benevolent jurisdictions and countries. 

I hope so!
