An airdrop is a distribution method used by cryptocurrency projects to distribute tokens or coins to a large number of individuals. It involves the free allocation of tokens to eligible participants, typically as a way to promote the project, increase its user base, or reward existing token holders.
During an airdrop, project organizers or developers specify certain criteria that participants must meet to qualify for the distribution. This can include holding a specific cryptocurrency, being an active user of a particular platform, or completing certain tasks or actions. These criteria vary depending on the project and its goals.
