A crypto airdrop is a promotional tool for crypto projects to generate hype around the project. The crypto projects behind these airdrops often directly deposit digital tokens into the wallets of active blockchain community members as a gift. Many of these airdrops have certain pre-set eligibility criteria that reward users for spreading awareness around the project. Although very popular during the early stages of the crypto ecosystem with the first airdrop coming in 2014, the marketing strategy has dimmed down in recent times, owing to regulatory scrutiny.
