Key Takeaways
- Most crypto losses come from scams and social engineering, not from hacking blockchains.
- Guaranteed returns, urgency, requests for your seed phrase and unsolicited contact are the biggest red flags.
- Common scams include fake investment platforms, romance ("pig butchering") scams, impersonation, phishing and rug pulls.
- Crypto transactions are irreversible, so prevention is far more effective than recovery.
Crypto scams cost victims billions of dollars every year, and they're getting more convincing. The good news is that almost all of them share the same warning signs. Learn these red flags and you'll avoid the vast majority of schemes.
9 red flags of a crypto scam
1. Guaranteed or unrealistically high returns
No legitimate investment can guarantee profits, especially in a market as volatile as crypto. Promises of "2% per day" or "double your money in a week" are always a scam.
2. Someone asks for your seed phrase or private key
No real exchange, wallet provider or support agent will ever ask for your seed phrase. Anyone who does is trying to steal your funds.
3. Pressure and urgency
"Act now," "limited spots" or "your account will be frozen" are designed to stop you from thinking clearly.
4. Unsolicited contact
Be suspicious of anyone who reaches out first through social media, dating apps, messaging apps or a "wrong number" text and steers the conversation toward crypto.
5. Impersonation of celebrities or companies
Fake giveaways using famous names ("send 1 ETH and get 2 back"), deepfake videos and accounts posing as exchange support are extremely common.
6. Platforms you can't verify
Scam "exchanges" and "investment apps" can show fake profits on a polished dashboard while your deposit is long gone. Stick to well-known, regulated platforms. Compare options on our best crypto exchanges page.
7. Fees to withdraw your "profits"
If a platform says you must pay a tax, fee or deposit before you can withdraw, it's almost certainly a scam, and paying will only lose you more.
8. Requests to install software or share your screen
Remote-access tools let scammers take over your device and accounts.
9. Anonymous teams and locked liquidity claims on new tokens
New tokens with anonymous developers, aggressive marketing and no real product are prime candidates for a rug pull.
The most common types of crypto scams
- Pig butchering (romance and friendship scams): scammers build a relationship over weeks, then introduce a "guaranteed" investment platform. Victims see fake gains, invest more and eventually can't withdraw.
- Phishing: fake websites, emails and ads that copy exchanges or wallets to steal logins and seed phrases.
- Wallet drainers: malicious sites that trick you into signing a transaction giving away permission to move your tokens.
- Impersonation and fake support: accounts posing as customer service, especially in replies to your public complaints.
- Giveaway scams: "send crypto to receive more back" schemes using celebrity or company names.
- Rug pulls and pump-and-dumps: developers or promoters inflate a token's price and then sell everything.
- Ponzi and fake mining schemes: early investors are paid with later investors' money until the scheme collapses.
- Recovery scams: after you've been scammed, fake "recovery experts" promise to get your money back for an upfront fee.
How to protect yourself
- Type exchange and wallet URLs directly or use bookmarks, rather than clicking ads or links.
- Use an authenticator app or security key for two-factor authentication.
- Keep long-term holdings in a hardware wallet and read every transaction before you confirm it.
- Regularly revoke token approvals you no longer use.
- Verify any opportunity independently and talk it over with someone you trust before sending money.
- Follow our 10 tips to keep your crypto safe.
What to do if you've been scammed
- Stop sending money, including any "fees" to unlock withdrawals.
- Secure your accounts: change passwords, revoke approvals and move any remaining funds to a new wallet.
- Document everything: wallet addresses, transaction IDs, messages and website URLs.
- Report it to the exchange you sent funds from and to authorities. In the US, that includes the FBI's Internet Crime Complaint Center (IC3) and the Federal Trade Commission. Other countries have similar fraud-reporting services.
- Beware of recovery scams promising to retrieve your funds for a fee.
Frequently asked questions
Can I get my crypto back after a scam?
Recovery is rare because transactions are irreversible, but reporting quickly gives exchanges and law enforcement the best chance to freeze funds that pass through regulated platforms.
How can I check if a crypto platform is legitimate?
Check whether it's registered with financial regulators where you live, search for independent reviews and warnings, and be wary of new platforms promoted through personal contacts.
Are crypto airdrops scams?
Some airdrops are legitimate, but unexpected tokens that appear in your wallet and point you to a website to "claim" them are a common way to lure you into signing malicious transactions. Don't interact with tokens you didn't expect.
