Recently, I saw someone pointing at on-chain large transfers and unusual activity in exchange hot and cold wallets, shouting "Smart money is here"… I usually take a moment to calm down: that's just money moving, it doesn't mean you should follow the trend. If you really want to look, I'm more concerned about whether there are traps left in my own wallet.

Mnemonic phrases are like the master key to your house; don’t screenshot, don’t store in the cloud, don’t send to "customer service," writing it down on paper is more reliable than saving it in an album. Signing authorization is more like lending your access card to a stranger, and not just once: some phishing sites make you click "confirm," which is actually giving them a long-term pass. Anyway, my red line now is: no unknown links, don’t sign if I don’t understand the content, limit the amount if I can authorize, and revoke after use. If code can be forked, don’t "fork" your wallet to others.
