To assess the legitimacy of an airdrop project, start by researching the team behind it. A legitimate project usually has a well-known and experienced team with a strong online presence, including profiles on LinkedIn or other professional networks. Check the project's whitepaper and roadmap for detailed information on its vision, goals, and future plans. Evaluate the project’s partnerships and collaborations with established players in the industry. Additionally, investigate the project's community engagement. Active discussions on Telegram, Twitter, or Discord indicate a legitimate interest and potential.
