Recently, I've been thinking about on-chain privacy again, and ordinary people really shouldn't have too many illusions. To put it simply, every transfer you make is like picking up a package at a neighborhood parcel locker, the locker number is anonymous, but if the property management (exchanges, analysis tools, nodes) really wants to check, by monitoring a series of access and entry records, they can still match it to a person. Compliance is not "suddenly coming to arrest you," more like the entry and exit points: KYC, risk control, freezing, which are basically unavoidable.

So my two expectations are: first, don't treat the chain as a safe deposit box; for sensitive operations, use different addresses and scenarios, don't just bind everything together for convenience; second, don't blindly believe that "privacy tools = invincible," using them poorly can make you more conspicuous... Recently, the NFT royalty debate also seems quite similar, everyone wants more freedom for secondary liquidity, but whenever money and rules are involved, there are always people trying to "align" them. Anyway, all I can do is expose less, regularly check authorizations and signatures, for now, that's it.
