These days, the community has been arguing again about privacy coins and coin mixing—whether they really count as "original sins." It’s a bit exhausting to watch... To be honest, ordinary users shouldn’t have overly romantic expectations about on-chain privacy: the blockchain is public, and privacy is more about "exposing less," not "completely disappearing." The boundaries of compliance are not determined by your belief that you haven't done anything wrong; when platforms/entry points/legal jurisdictions tighten up, the trouble might randomly fall on you.

My own approach is very laid-back: avoid using it if you can, and if I do use it, treat it like a disposable raincoat—don’t keep it on long-term, and I even take screenshots (yes, that old trick) to keep a record of my actions and origins, so I won’t panic when I need to explain it someday. Anyway, don’t get carried away, and don’t treat "privacy" as a talisman.
