The Most Common Crypto Scams

| Ponzi/MLM | Unsustainable yields, recruit to earn | $1K-$100K+ | Medium |
Red Flags to Watch For
- Guaranteed returns: No legitimate crypto project guarantees returns. If anyone promises "10% daily" or "guaranteed profit," it is a scam.
- Urgency pressure: "Limited time offer," "only 100 spots left," "invest now or miss out" — scammers create urgency to prevent rational decision-making.
- Anonymous team: If the founding team is anonymous with no verifiable track record, proceed with extreme caution.
- Unverified contracts: Always verify smart contract addresses on the official project website. Scammers create fake tokens with identical names.
- DMs from strangers: No legitimate project will DM you first. Ignore all unsolicited messages on Telegram, Discord, and Twitter.
How to Protect Yourself
Use a separate wallet for DeFi: Create a dedicated wallet for interacting with DeFi protocols. Keep your main holdings in a separate hardware wallet that never connects to unknown contracts.
Revoke token approvals: Regularly check and revoke unlimited token approvals using Revoke.cash or Etherscan's token approval checker.
Verify everything: Bookmark official exchange URLs. Use hardware 2FA (YubiKey) instead of SMS. Triple-check addresses before sending large amounts.
If it seems too good to be true: It is. Always.
Frequently Asked Questions
What is the most common crypto scam?
Phishing is the most common — fake websites and emails that steal login credentials or seed phrases. Always verify URLs and never click links in unsolicited messages.
How do I know if a crypto project is a scam?
Red flags: guaranteed returns, anonymous team, no audit, urgency pressure, unrealistic yields, and requirement to recruit others. If it seems too good to be true, it is.
Can I recover money lost to a crypto scam?
Rarely. Once crypto is sent, transactions are irreversible. Some law enforcement agencies have crypto investigation units, but recovery rates are very low. Prevention is the only reliable protection.
Are hardware wallets safe from scams?
Hardware wallets protect against remote hacking but not against social engineering. If you are tricked into signing a malicious transaction or revealing your seed phrase, your funds can still be stolen.
