An airdrop in the cryptocurrency world refers to the distribution of free tokens or coins to the wallets of active blockchain community members. These distributions are often used as a marketing strategy to promote a new cryptocurrency, reward loyal users, or increase the token's circulation. Here’s a detailed look at airdrops:

1. Purpose of Airdrops

Promotion: To create awareness and attract attention to a new cryptocurrency or project.

Rewards: To reward loyal users or early adopters of a blockchain platform.

Decentralization: To distribute tokens widely, ensuring a more decentralized ownership.

Community Building: To engage and grow a community around a project.

2. How Airdrops Work

Snapshot: A snapshot of the blockchain is taken at a specific block height to identify eligible wallets.

Distribution: Tokens are distributed to the identified wallets based on predefined criteria.

Criteria: Eligibility can be based on factors like holding a specific cryptocurrency, participating in certain activities, or simply being an active member of the community.
