Bustabit no longer allows bankroll investors/participants unless they follow the new KYC rules implemented by the new owner. They are following legal advice therefore cannot be blamed however they are not asking game players and previous bankroll investors to send KYC. Their KYC rule is specific to new bankroll investors only because they will not allow investors from restricted locations.
At the moment, bustabit and bustadice are two crypto casinos without KYC. Btw one thing that gives me hope is web3 casinos.
