Disclaimer: Crypto airdrops are promotional events where tokens are distributed to existing holders of a cryptocurrency or to individuals who meet certain criteria. While airdrops can be a way to acquire tokens at no cost, they also involve risks. There’s no guarantee that the airdropped tokens will increase in value, and there may be associated fees or requirements. Additionally, airdrops can be susceptible to scams and phishing attempts. Always exercise caution and verify the legitimacy of any airdrop opportunity before participating.
