Recently, I saw someone discussing on-chain privacy again. To put it simply, ordinary users shouldn't think of it as a "cloak of invisibility." On-chain is a public ledger; at most, it makes it less easy for others to immediately link you to your real-world identity. But if someone really wants to investigate, or if it goes through compliance procedures, exchanges and entry/exit points are still unavoidable. My expectation is very simple: expose as little as possible, don't link your salary card, regular email, and common addresses all together, use several wallets, and stop using them after you're done—keep things cleaner.

Additionally, before and after the upgrade of that mainstream public chain, everyone in the group was guessing whether the project would migrate. I'm more concerned about one thing: once on-chain behavior crosses chains or Layer 2 solutions, the traces are more numerous and easier to piece together. Be disciplined, withdraw once you've completed your tasks, and don't get into prolonged battles.
