What is Airdrop?
An airdrop is a distribution of free tokens to existing wallet addresses — typically rewarding early users, community members, or holders of specific tokens as a user acquisition and decentralization strategy.
WHY IT MATTERS
Airdrops are crypto's user acquisition tool. Instead of spending on ads, protocols distribute tokens to their early users and community. Uniswap's UNI airdrop (400 UNI to every past user) was worth ~$12,000 at peak — a powerful incentive that rewarded genuine usage.
Airdrops serve multiple purposes: decentralizing token ownership, rewarding early adopters, bootstrapping governance participation, and generating buzz. They've become an expected part of the crypto playbook.
The downside: airdrop farming (using protocols purely to qualify for future airdrops) distorts usage metrics and can lead to immediate selling pressure when tokens are distributed.
