### What Are Crypto Airdrops?
Crypto airdrops are a marketing strategy used by blockchain-based projects to distribute free tokens or cryptocurrencies to a large number of wallet addresses. The goal is often to promote the project, incentivize user engagement, or reward loyal community members.
### How Do Airdrops Work?
1. **Announcement**: A project announces an airdrop through social media, forums, or their official website.
2. **Eligibility Criteria**: Participants usually need to meet specific criteria, such as holding a particular token, participating in the community, or completing certain tasks.
3. **Distribution**: Tokens are distributed to eligible participants, often directly to their wallets.
### Types of Airdrops
1. **Standard Airdrops**: Tokens are distributed to users who sign up or register for the airdrop. No specific action is required other than providing a wallet address.
**Example**: OmiseGO (OMG) airdrop distributed tokens to Ethereum holders.
2. **Holder Airdrops**: Tokens are given to holders of a specific cryptocurrency, typically based on a snapshot of blockchain activity at a particular time.
**Example**: Stellar (XLM) airdropped tokens to Bitcoin holders.
