### What is a Crypto Airdrop?
A crypto airdrop is a marketing strategy used by blockchain-based projects to distribute free tokens or coins to a large number of wallet addresses. The primary aim is to promote awareness and adoption of the project, reward loyal users, or achieve a decentralized distribution of the cryptocurrency.
### How Do Airdrops Work?
Crypto airdrops involve distributing tokens to existing cryptocurrency holders or participants in the project's community. Here's how they typically work:
1. **Snapshot:** The project takes a "snapshot" of the blockchain at a specific date and time to record the wallet addresses and their holdings.
2. **Distribution:** Tokens are distributed to eligible wallets based on predefined criteria, which may include holding a specific amount of another cryptocurrency or participating in community activities.
3. **Claim Process:** Some airdrops require recipients to claim their tokens manually by connecting their wallets to the project's website or dApp (decentralized application).
### Types of Airdrops
1. **Standard Airdrops:** Tokens are distributed to all holders of a specific cryptocurrency, such as Bitcoin or Ethereum.
- *Example:* In 2017, the OmiseGO (OMG) airdrop distributed tokens to Ethereum holders.
2. **Bounty Airdrops:** Users complete specific tasks, such as promoting the project on social media, writing blog posts, or joining the project's Telegram group.
- *Example:* The Stellar (XLM) airdrop in 2018 required participants to verify their identity through the Keybase platform.
3. **Holder Airdrops:** Tokens are distributed to holders of a specific token. Often, the more tokens held, the more airdropped tokens recei.
