Honestly, ordinary users shouldn't have too high expectations for on-chain "privacy." What you can do more is to reduce the exposure: don't use an address as an ID card, don't follow the same path for everything, and minimize permissions whenever possible. When it comes to the "regulatory boundary," on-chain data is naturally traceable; with exchanges/entry points cooperating, many things are actually not mysterious anymore. I’m also not sure what level of invisibility everyone is actually expecting.

Recently, before and after that mainstream public chain upgrade/maintenance, the group was guessing whether projects would migrate. I'm actually more concerned about: whether they migrate or not, it’s the same; cross-chain transfers, address changes, airdrop interactions—these make the profile more complete... Anyway, my current expectation is: privacy is a cost, not a default property; compliance is not an enemy, but don’t expect "technology" to help erase all traces. That’s all for now.
