An Airdrop in the context of cryptocurrency refers to the distribution of free tokens or cryptocurrencies to a specific group of users. It is usually carried out by blockchain projects as a marketing or promotional strategy to increase their user base and raise awareness about their project. Airdrops can be targeted to existing token holders of a particular blockchain, users who participate in certain events or tasks, or even distributed widely to the entire crypto community. Recipients of the airdropped tokens may hold them as an investment, use them within the project's ecosystem, or exchange them on cryptocurrency exchanges for other digital assets.
