I only take one note: on-chain privacy should not be imagined as a "cloak of invisibility," but more like curtains—if you want to hide, you have to accept that people inside the house might also be watching. Whether it's compliant or not, recently the community has been torn apart over privacy coins/mixing coins, which is normal. To put it simply, ordinary users have two expectations: don't treat "privacy tools" as a get-out-of-jail-free card, and if you really use them, do so under the premise that they can be explained and proven not to be malicious. Otherwise, when the wind tightens, the first to panic will be yourself.
