Participating in airdrops can be profitable, but it is essential to maintain security. Be wary of exaggerated promises and never share your private key. Use a separate wallet solely for airdrops and avoid clicking on unknown links sent via email or social media. Verify if the project is legitimate: research the team, read the whitepaper, and check official channels. Use two-factor authentication (2FA) whenever possible. Avoid connecting your wallet to suspicious sites and, if possible, use wallets with limited permissions. Security begins with information — stay informed and protect your assets.
