A crypto airdrop is a distribution of cryptocurrency tokens or coins, usually for free, to a large number of wallet addresses. Airdrops are typically used as a marketing strategy by blockchain-based projects to promote their new cryptocurrency, increase awareness, and incentivize the adoption of their platform. Recipients of the airdrop may need to meet specific conditions, such as holding a minimum amount of a particular cryptocurrency, engaging with the project on social media, or completing specific tasks. The goals are to increase the user base, create buzz around the project, and achieve a wider distribution of the tokens.
