### What Are Crypto Airdrops?
Crypto airdrops are a method used by blockchain projects to distribute free tokens or cryptocurrencies to a specific group of people, typically to promote awareness and encourage adoption of the project. The recipients might include current holders of a particular cryptocurrency, early adopters, or users who perform specific tasks.
### How Do Crypto Airdrops Work?
1. **Announcement**: The project team announces the airdrop through various channels such as social media, forums, or their official website.
2. **Eligibility**: Criteria for eligibility are specified. This could include holding a specific cryptocurrency, signing up for a newsletter, or performing certain tasks.
3. **Snapshot**: For holder-based airdrops, a "snapshot" of the blockchain is taken at a particular block height or timestamp to determine who qualifies.
4. **Distribution**: Tokens are distributed to the eligible wallets either immediately or at a specified future date.
### Types of Crypto Airdrops
1. **Standard Airdrops**: Tokens are distributed to users for free, often based on a snapshot of holdings of a particular cryptocurrency.
*Example*: OmiseGO (OMG) airdropped tokens to Ethereum holders.
2. **Bounty Airdrops**: Users perform certain tasks to receive tokens. Tasks can include promoting the project on social media, signing up for a newsletter, or joining a Telegram group.
*Example*: BitTorrent (BTT) distributed tokens to users who completed social media tasks.
3. **Holder Airdrops**: Tokens are given to holders of a specific cryptocurrency. The amount received is often proportional to the amount held.
*Example*: Stellar (XLM) distributed tokens to Bitcoin holders.
4. **Exclusive Airdrops**: Tokens are distributed to a specific group, such as early adopters or contributors to a project's development.
*Example*: Uniswap (UNI) airdropped tokens to users who had used the platform before a certain date.
5. **Hard Fork Airdrops**: New tokens are distributed to holders of the original cryptocurrency after a blockchain splits (forks).
*Example*: Bitcoin Cash (BCH) distributed to Bitcoin (BTC) holders after the Bitcoin fork.
### Examples of Notable Airdrops
1. **Uniswap (UNI)**: In September 2020, Uniswap airdropped 400 UNI tokens to every user who had used the platform prior to a certain date.
2. **Stellar (XLM)**: In 2018, Stellar airdropped $125 million worth of XLM to users of the blockchain wallet provider Blockchain.com.
3. **Bitcoin Cash (BCH)**: In 2017, Bitcoin holders received BCH tokens after the Bitcoin network forked.

4. **Check Project Websites**: Regularly visit the websites and blogs of projects youâre interested in, as they often announce airdrops there.
5. **Participate in ICOs and New Projects**: Engaging with new projects, such as participating in ICOs or using beta versions of dApps, can sometimes make you eligible for airdrops.
6. **Use Crypto Wallets with Airdrop Features**: Some wallets, like Trust Wallet and MetaMask, have features or partnerships that facilitate airdrop participation.
