A casino is a profitable business so it needs a license to be considered legitimate by the government and a casino cannot be anonymous if it has a license, but this is pretty much the same way CEX works.
So the casino will keep a close eye on its users if caught then they will take action against the user.
The government cannot be blamed even if they themselves are laundering the money, and usually the government is unlikely to do so.
Y you're right, casinos that are already legal and licensed by the local government will have the authority to enforce KYC at a certain withdrawal rate, so this can prevent money laundering from happening because they will know who is trying to launder money.
That is, the ones that allowed the casino to be used as a money laundering tool were the ones that did not have wagering requirements, and usually did not have a license either. There are almost none of those left, and two examples we have in the forum would be freebitco.in and Lightlord casinos that do not give much confidence, so those who want to launder better look for other ways.
Yes there are hardly any such casinos left, in the sense that all casinos are now here licensed and this wagering requirement has become mandatory for all casinos so that there is no money laundering in the casino.
I heard the case of freebitco.in and Lightlord for a long time but did not pay attention so clearly, but it is very unfortunate that the casino that was built for many years had to destroy its reputation because of its own actions, let alone allegations of money laundering in other ways.
