### 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.

**Example**: BitTorrent (BTT) conducted a bounty airdrop requiring social media activity.
