In this circle, the water is deep. Many times, it's not that you are not smart, but that the scammers are too professional. When I was new to airdrops, I fell for a scam once. The other party disguised themselves as customer service from the project team and made me connect my wallet to sign an operation, resulting in one NFT being swept 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. Regularly clean up wallet permissions, don't wait until something happens to think about it. One more very important point: don't be greedy; all 'guaranteed returns' are traps. The money is yours, and safety always comes first.
