An airdrop is a distribution of tokens or digital assets to a group of individuals or accounts. The term comes from the idea of dropping something from the air or sky, in this case, tokens, coins or digital assets. The distribution can be performed in a variety of ways, such as through social media campaigns, as a reward for participating in a project, or as a way to introduce a new cryptocurrency or blockchain project. Airdrops can be an effective way to increase brand awareness, create a community around a project, and distribute tokens more widely.
