You are correct at some point when you talk about the safety of bettors who must have complete information about the owner to keep themselves safe but that doesn't mean that owners can't launch a casino. They can start without a license or giving any information about them but it should be a P2P gambling site and they will work as escrow 'where the only condition remains that they don't cheat'. OneHash is the best example for this. How can a decentralized gambling website paying automatically to their customers on each win need to expose about the owners of that business?
