Recently, I've seen people focus on on-chain large transfers and unusual activity in exchange hot and cold wallets, saying things like "smart money is coming/going." I also pay attention, but honestly, those signals are quite noisy and can easily lead people astray. Instead, the more critical but less obvious issue is: contract approvals still set to unlimited, which is like leaving the door unlocked. Being cautious during the day doesn't matter; accidents can still happen at night. Revoking permissions is really like turning off the lights and locking the door before sleep—there's no profit, but it greatly reduces the chance of bad luck.

I personally trust data a bit more: approval lists and interaction records are concrete; intuition is more of a reminder to "close the umbrella first," but ultimately, I still need to check. Anyway, my current habit is: revoke permissions after use, set limits where possible, to avoid waking up one day with an empty wallet and still wondering who the smart money is.
