Scammers often create fake airdrop campaigns to steal funds or personal data. A key red flag is any airdrop that requires you to send crypto in return for tokens—legitimate airdrops never ask for payment. Always check official project announcements and avoid engaging with suspicious links or unsolicited messages. If a project asks for wallet permissions beyond viewing balances, it may be an attempt to drain funds. Staying informed through trusted crypto communities and security audits helps identify fraudulent schemes before falling victim.
