Crypto’s speed and irreversible transactions make it a favourite tool for fraudsters. Billions are lost every year to crypto scams, and young people active on social media are frequent targets. Knowing the patterns is the best protection.
The most common crypto scams
| Scam | How it works |
|---|---|
| Fake investment platforms | Websites or apps show fake profits, then block withdrawals or demand “fees” |
| Romance and “pig butchering” | A new online friend builds trust, then introduces a crypto investment |
| Giveaway scams | Impersonated celebrities promise to double any crypto you send |
| Phishing | Fake sites or messages steal logins or recovery phrases |
| Fake support agents | “Support” contacts you and asks for your recovery phrase or remote access |
| Pump and dump | Influencers hype a token, then sell as prices spike |
| Recovery scams | Scammers offer to recover lost funds for a fee |

Warning signs
- Guaranteed or very high returns.
- Pressure to act quickly.
- Requests to pay through crypto ATMs or gift cards.
- Anyone asking for your recovery phrase or private keys.
- Unregistered platforms or no clear company details.
- Withdrawals that require extra fees or taxes paid upfront.
How to protect yourself from crypto scams
- Never share your recovery phrase. No legitimate person or company needs it.
- Use regulated platforms registered with your country’s regulator.
- Bookmark official sites and avoid clicking links in messages.
- Turn on app-based two-factor authentication.
- Verify identities independently before sending money.
- Start small with any new platform and test withdrawals.
- Talk to someone you trust before investing in an opportunity from social media or a dating app.
What to do if you have been scammed
- Stop sending money immediately.
- Collect evidence: wallet addresses, transaction IDs, screenshots and messages.
- Report to the platform used and change your passwords.
- Report to authorities: the FBI’s IC3 and the FTC in the US, Action Fraud in the UK, the Canadian Anti-Fraud Centre in Canada, and the EFCC or police in Nigeria.
- Be wary of anyone promising to recover funds for a fee.
Crypto scams in Nigeria
Nigeria has seen many Ponzi-style “investment” schemes and fake trading platforms promising fixed monthly returns. Check SEC Nigeria’s list of registered digital asset operators and its warnings before investing. If a scheme pays early investors from new deposits, it is likely to collapse.

Real-life crypto scam scenarios
These common patterns show how crypto scams unfold:
- The helpful stranger: a friendly contact on a dating app shares “trading tips” and a platform link. Early profits appear, but withdrawals need a “tax payment”.
- The fake support desk: after you post about a wallet problem, “support” messages you and asks for your recovery phrase.
- The giveaway: a video shows a famous entrepreneur promising to double any crypto sent.
- The task job: an online job pays small commissions, then asks you to deposit crypto to unlock bigger tasks.
If you recognise any of these, stop and verify independently. Legitimate opportunities never require secrecy, urgency or your recovery phrase.
