“Crypto airdrop” is a popular search, and for good reason. Free tokens sound like the easiest money in crypto. But airdrops are also one of the most common lures in crypto scams. This guide explains what a real airdrop is, why projects run them, and the warning signs of a fake.
What an airdrop is
Wikipedia defines an airdrop as an unsolicited distribution of a cryptocurrency token or coin, usually for free, to many wallet addresses. Airdrops usually accompany the launch of a new cryptocurrency or DeFi protocol, as a way to gain attention and followers. They aim to tap the network effect by reaching people who already hold Bitcoin, Ethereum or similar assets.
In other words, an airdrop is marketing. Projects give away tokens because they want users, liquidity and attention. That does not make the token valuable, and it does not mean the project is trustworthy. Our article on FOMO design in token sales explains why “free” offers are designed to rush you.
Tax is not free
In the United States, airdrops have raised policy questions about tax liability, including whether they count as income or as capital gains. Rules differ by country, including Finland. Keep a record of the date and the market value whenever you receive or sell airdropped tokens.
How fake airdrops work
According to Wikipedia, a crypto giveaway scam involves scammers who hack or impersonate celebrities, influencers or well-known companies. They falsely claim to multiply cryptocurrency or to give it away through an airdrop, and they promote this through social media posts and livestreams. Common patterns include:
- “Send to receive”: any request to send crypto first to “verify” or “unlock” your airdrop is a scam.
- Fake claim sites: a link leads to a copy of a project website that asks you to connect your wallet and sign a transaction. That signature gives a drainer contract permission to spend your tokens.
- Seed phrase requests: no legitimate airdrop needs your seed phrase. Read our seed phrase safety checklist.
- Unsolicited tokens in your wallet: random tokens can lead to scam sites when you try to sell them. Ignore unknown tokens.
Drainers and stealers
Wikipedia describes stealers, also called drainers or infostealers, as malware that steals private information, including private keys from crypto wallets. They often scan computers for wallet files and record keystrokes. A fake “airdrop checker” app is a classic way to deliver this malware.
A safe airdrop routine
- Only find airdrop announcements on the project’s official site or verified accounts. Type the address yourself.
- Use a separate wallet with small balances for claims.
- Read what you are signing. Never approve unlimited token allowances to a claim contract.
- Never send funds to “receive” an airdrop.
- Revoke approvals after claiming.
- Check the launchpad’s vesting and unlock calendar before treating airdropped tokens as worth anything.
Red flags at a glance
- Time pressure, such as “claim in the next 30 minutes”.
- A celebrity or exchange account promising to “double” anything you send.
- A claim site whose address differs by one character from the real one.
- A wallet pop-up asking for “setApprovalForAll” or an unlimited allowance just to claim.
- A support agent who contacts you first in a direct message.
- A “checker” app or browser extension you have to install.
Why legitimate airdrops still carry risk
Even a genuine airdrop can hurt you. New tokens often have thin liquidity, so trying to sell can move the price sharply against you. Large unlocks for team and investor wallets can follow soon after launch. The project may also fail long before the token finds any lasting value. As noted above, tax may be due on the value when you received the tokens, even if the price later collapses. Treat airdrop tokens as speculative, not as income you can count on.
If you clicked a fake link or signed something suspicious, act quickly. Revoke approvals, move your remaining funds to a fresh wallet and report the scam to the platform where you saw it.
