$BTC 1. Verify Project Authenticity Before participating in any airdrop, make sure to verify the background and credibility of the project. Check the project's official website, whitepaper, information about the development team, and development progress[^0^]. At the same time, you can also refer to community feedback and evaluations to understand the experiences of other investors through social media, forums, and other channels[^1^]. Pay attention to whether the airdrop activity is initiated by well-known project parties or organizations recognized by the community[^2^]. 2. Protect Personal Information and Asset Security Use Independent Wallets: Dedicated airdrop wallets can prevent total asset loss due to the theft of a single wallet[^3^]. It is recommended to use hardware wallets (such as Trezor or Ledger) to store private keys[^4^]. Avoid Disclosing Sensitive Information: Never disclose your wallet private key or seed phrase during airdrop activities; any airdrop that requests this information may be a scam[^5^]. At the same time, be cautious when filling out personal information, and avoid disclosing your ID number, mobile phone number, etc., on insecure websites or platforms[^7^]. Check Transaction Details: When interacting with smart contracts, be sure to check whether the Gas limit for the transaction is abnormally high, as this may be a sign of a malicious contract[^8^].
