In this circle, the waters are deep; often, it's not that you're not smart, but that the scammers are too professional. When I first got into airdrops, I fell for a scam once. The other party disguised themselves as customer service from the project side and asked me to connect my wallet and sign a transaction, resulting in one NFT being directly taken away. Later, I summarized: 1. Don't click on links casually, especially those shared in groups; 2. Only trust official websites and verified accounts; 3. Periodically clean up wallet permissions; don't wait until something happens to remember. One more very important point: don't be greedy; all 'guaranteed returns' are bait. The money is yours, and safety should always come first.
