Unfortunately, yes. Soon all the casinos will have mandatory KYC. At least any significant casino will, if not already. You see stake which is among the most reputed casinos, they too demand KYC now and place users in withdraw-only mode. I am not against them because they allowed people to play without KYC for as long as they could, but they do have legal obligations, especially once they grow as big as they are.

Now new casinos operate without KYC but once they get big enough, they follow the suit. It's pretty obvious that anyone who wants to run a successful casino on a large scale has to make KYC mandatory otherwise they get surrounded by legal issues.
