So the question is, does using a mixer put us at risk when dealing with casinos? Are we better off keeping privacy tools away from gambling wallets, or should we expect casinos to respect privacy since this is crypto in the first place?
I think that basically, we should just read the terms of service of a casino to avoid any issues with them. Anyone who is concerned about privacy will basically find it hard to gamble in a casino unless they use and offshore casino that is not regulated. In the first place you already submitted KYC documents, your privacy is already gone. Using a mixer after this has been done is raising a red flag and the casino has every right to protect themselves by doing a thorough investigation before releasing your winnings.
