These past few days, I've seen a bunch of people clicking links everywhere to test network points, and guessing whether the mainnet will issue tokens... Honestly, the most expensive thing is often not the gas, but that one slip-up in authorization. Mnemonic phrases, any page asking for them should be closed immediately—there's no such thing as "verification" or "airdrop registration" that's trustworthy.

I myself have made a mistake: once I didn't understand a "task site," and thought I was being cautious enough, but the signature popup was confusing as hell. I reluctantly clicked confirm... only to find out I had given unlimited authorization. Luckily, there wasn't much in my wallet at the time, so I just took it as a lesson learned. Now I have one rule: if you don't understand it, don't do anything. Better to miss out on points than to treat your wallet like a prize pool for others to draw from. Revoke permissions, split assets, use cold wallets—there's nothing shameful about it.
