The only reason the casinos ask for KYC is a way of not paying. In Curacao all the casinos work under a sub-license under one of the four master licenses. In the UK and US, licensing is strict. It's not that way for bitcoin casinos.
And if they want to handle fiat money in the future and be operational it would be foolish from them not to complain with AML laws, because why would they risk their existence and wouldn't do that?
License, as I understand, is more to do with law requirements, than with behavior of the licensed casino. Gambling is either banned or toughly restricted in most of the world, so it's really a trouble for such business owners to legalise the income from this, so that the little amount of places whose authorities are allowed to license casinos are in a huge favour of casino owners. So control functions of licensing authorities are a bit limited under such circumstances.
The authorities and everything that has to do with it will never support the casinos, because they do not receive money, everything is for the house and for the owner, the way they can control and receive some money is by demanding licenses and data to be able to start pressing, I think that things that are games of chance, sports betting are considered bad by many, and not as a Style of entertainment,everyone blames the casinos for addictions, but the culprits are not the casinos, They are the same people who do not control themselves.
