Free Crypto — But Is It Really?
“Airdrop” is one of the most exciting words in crypto. The idea of receiving free tokens just for using a protocol or holding certain assets is genuinely appealing.
But airdrops are more complex than they first appear. Here’s everything you need to know.
What Is a Crypto Airdrop?
A crypto airdrop is the distribution of free tokens or coins to wallet addresses, usually as a reward for past behaviour or to promote a new project.
Airdrops can be worth anything from a few pence to tens of thousands of pounds — depending on the project and how much you’ve used it.

Why Do Projects Do Airdrops?
Reward Early Users
The most legitimate reason. Projects reward the people who took a risk using their product before it was popular.
Decentralise Token Ownership
For a protocol to be truly decentralised, its governance token needs to be widely distributed. Airdrops achieve this quickly.
Generate Awareness
Airdrops create buzz. When thousands of people suddenly receive tokens, many go and learn about the project — free marketing.
Bootstrap Community
Token holders become stakeholders. They’re incentivised to support, promote, and govern the protocol.
Famous Airdrops in Crypto History
| Project | Year | Amount | Peak Value |
|---|---|---|---|
| Uniswap (UNI) | 2020 | 400 UNI per user | ~$3,000+ |
| ENS (Ethereum Name Service) | 2021 | Variable by usage | Thousands for heavy users |
| Arbitrum (ARB) | 2023 | 625–10,000+ ARB | Hundreds to thousands |
| Optimism (OP) | 2022 | Variable | Hundreds per user |
| dYdX (DYDX) | 2021 | Variable by trading | Thousands for active traders |
The Uniswap airdrop in 2020 gave 400 UNI to everyone who had ever used the platform — worth over $1,200 at launch and much more at peak.
Types of Airdrops
Retroactive Airdrops
The most valuable type. The project secretly takes a snapshot of who has used their product, then distributes tokens to those addresses.
You don’t know it’s coming — you just have to use good protocols early.
Holder Airdrops
Distributed to holders of a specific token. If you hold ETH, BTC, or a specific NFT, you may receive tokens from new projects.
Task-Based Airdrops
Require you to complete specific actions:
– Follow on Twitter
– Join a Telegram group
– Sign up to a waitlist
– Refer friends
These tend to be lower value than retroactive airdrops.
Hard Fork Airdrops
When a blockchain splits (hard fork), holders of the original coin often receive an equivalent amount of the new coin.
Example: When Bitcoin Cash forked from Bitcoin in 2017, all BTC holders received an equivalent amount of BCH.
How to Position Yourself for Airdrops
The key to maximising airdrop opportunities is using new protocols early and genuinely.
Step 1: Use New Protocols Early
Projects reward real users. Use DeFi protocols, bridges, DEXs, and other applications — especially on newer chains.
Step 2: Interact Regularly
Many airdrops are weighted by frequency of use, volume traded, or length of engagement.
Step 3: Hold Relevant Tokens
Some airdrops go to holders of specific tokens or NFTs.
Step 4: Participate in Testnets
Many projects run public testnets before launch. Testnet participants are often rewarded.
Step 5: Stay Informed
Follow crypto news, Twitter/X, and Discord communities. Announced airdrops often have eligibility deadlines.
Airdrop Scams: How to Stay Safe
Airdrops are also one of the most common vectors for scams.
Common Airdrop Scams:
Fake airdrops asking for your seed phrase
Never, ever enter your seed phrase to claim an airdrop. This is always a scam.
Approval scams
You’re sent tokens, then asked to “approve” a contract to claim them. The approval actually gives the scammer unlimited access to drain your wallet.
Phishing sites
Fake websites mimicking legitimate projects. Always verify URLs carefully.
Dust attacks
Tiny amounts of tokens sent to your wallet to track your transactions or lure you into interacting with a malicious contract.
Safety Rules:
– Never share your seed phrase
– Only claim airdrops from official project websites (verify via official Twitter/Discord)
– Check contract approvals before signing — use tools like Revoke.cash
– If unsure, use a separate “burner” wallet for claiming unknown airdrops

Tax on Airdrops
In most countries, airdrops are taxable as income at the time of receipt.
UK (HMRC): Airdrops received for nothing are generally not taxable at receipt, but gains on disposal are subject to CGT. If received in exchange for a service, Income Tax applies.
US (IRS): Generally taxed as ordinary income at fair market value when received.
Always consult a tax professional for your specific situation.
Key Takeaways
– Airdrops are free token distributions — often rewarding early users of a protocol
– Retroactive airdrops (surprise distributions to past users) are the most valuable
– To maximise opportunities: use new protocols early, interact regularly, hold relevant tokens
– Airdrop scams are rampant — never share your seed phrase to claim anything
– Airdrops may be taxable as income in your country
The Bottom Line
Airdrops can be genuinely life-changing — a single interaction with a new protocol might be worth thousands of pounds years later. But they reward genuine engagement, not speculation.
Use good products, stay safe, and the airdrops will sometimes find you.
NOT FINANCIAL ADVICE. Airdrops carry tax implications and scam risks. Always do your own research (DYOR) and consult a tax professional.
