In the past few days, everyone has been watching the main public chain upgrade/maintenance, and the group has started guessing whether the "ecosystem will migrate."

I think whether it migrates or not is just superficial; the underlying issue remains: how far can on-chain privacy go, and where will it be restricted by compliance?

Ordinary users, don't fantasize that "anonymity = security."
Honestly, most of the time you're just hiding your name; your behavioral trail is still there.
When exchanges deposit and withdraw, and wallets are linked to your phone/browser, it's not hard to match them.
Compliance isn't about completely sealing off privacy; it's more like drawing a line: you can prevent the whole network from watching, but don't expect this line to block all traceability.

My current expectation is very low:
Expose as little as possible, don't treat privacy as a talisman, don't see compliance as an enemy...
What I've learned isn't techniques, but rather accepting the fact that "there's no perfect invisibility on the chain."
