Back when I was running nodes, I was still naive, thinking that on-chain "anonymity" was pretty reliable. It wasn't until I had a crash that I realized: the issue of public ledgers is more about the probability of "being watched" than just opening a mixer and everything's fine. Don't expect compliance boundaries to be too clear-cut; often, they are drawn in hindsight. What you think is a normal transfer can turn into a different story once someone tags it.

Recently, those on-chain data tools and tagging systems have been criticized for being outdated or easily misled, but I’m not surprised: frankly, they’re also guessing, just guessing in a way that’s more or less plausible. I think the expectations of ordinary users boil down to two points: don’t treat privacy as a shield, and don’t see compliance as a get-out-of-jail-free card; for daily operations, layer your actions when possible, don’t reuse addresses randomly, keep important assets cold, and keep good records and backups… as for the rest, just endure it slowly.
