Recently, I've seen everyone rushing to test network incentives, earning points like crazy, and constantly guessing whether the mainnet will issue tokens or not. I just can't hold back anymore... To be honest, you can earn some rewards, but don't cross the red line. As for mnemonic phrases, unless you're planning to give your wallet to someone else, any "customer service/activity/airdrop form" that asks you to fill it out should be considered phishing. Also, for signature authorization, don't just click confirm on every pop-up, especially those that say "authorize first, then claim," as the scope of authorization can be so broad that it could turn your assets into a buffet. Anyway, my current principle is: better to earn fewer points than to gamble your wallet on human nature. Being cautious is not shameful.
