Crypto airdrops are a marketing strategy used by blockchain projects to distribute free tokens or coins to the cryptocurrency community. Here's how they generally work:
1. **Announcement:** The project announces the airdrop, often via social media, forums, or their website.
2. **Eligibility Criteria:** Users must meet specific criteria, such as holding a certain amount of a particular cryptocurrency or completing tasks like joining a Telegram group or following on Twitter.
3. **Distribution:** Eligible users receive free tokens directly into their wallets.
Airdrops are used to increase awareness, reward loyal users, and decentralize token ownership.
