Airdrops:

Definition: An airdrop refers to the distribution of free tokens or cryptocurrencies to a large number of wallet addresses. These distributions are often used as a marketing strategy to raise awareness, reward existing users, or bootstrap a new blockchain project.

How it works: Airdrops can occur for various reasons. Some projects distribute tokens to holders of a specific cryptocurrency (like Bitcoin or Ethereum) to encourage them to try a new project. Others may require participants to complete certain tasks, such as following social media accounts, referring friends, or holding a minimum amount of a particular cryptocurrency.

Purpose: Airdrops can help increase the user base of a new cryptocurrency or blockchain project and create a sense of community. They can also be used to distribute tokens fairly among existing users or to attract attention to a particular aspect of a project.
