My expectations for on-chain privacy have always been quite "low": if you're using a public ledger, don't expect it to be as untraceable as cash. Frankly, it can only be made to look "less understandable"; if you really want compliance checks, exchange cooperation, and on-chain analysis, ordinary people will basically have no way to hide... So my current boundary is: don't leave unnecessary personal clues on the chain, don't treat an address as an ID that lasts forever, split them up when possible, and if you miss the chance, so be it.

Recently, everyone has been talking about AI Agent automated trading. I reacted a bit slowly, and seeing a bunch of "fully automatic passive income" made me want to sleep. Anyone can boast about the narrative, but safety is really about paying attention to details: granting unlimited permissions once authorized, scripts running and interacting chaotically, and in the end, privacy isn't really increased much, with wallets just running bare. Anyway, I take a laid-back approach—manual when possible, fewer permissions when I can, so I can sleep more peacefully.
