Recently, I saw people arguing over "L2 who has the highest TPS, lowest fees, and most subsidies," but I'm actually more concerned about: don't step on that line in your wallet.

Mnemonic phrases, to put it simply, are the key to life; screenshots, cloud storage, sending them to "customer service"—don't even think about it... Better to write two copies by hand and keep them separate.
And then there's signature authorization—many phishing sites don't ask you to transfer funds directly; they just get you to sign something incomprehensible, and the next second, you become a "voluntary donor."
Now, when I see a pop-up asking for a signature, I pause for three seconds first; if the address is wrong, the domain looks suspicious, or the permissions are too broad, I just close it—better to miss an airdrop than become a leek.
Really can't take it anymore.
That's all for now.
