Part 3 of our "Crypto Explained Well" series. Most crypto scams aren't sophisticated — they rely on urgency and on victims not knowing the seven tells. Here they are, fast.
You usually have about a minute's worth of warning signs before a crypto scam takes your money — if you know what to look for. None of these requires technical skill. They're pattern-recognition, and the patterns barely change.
The Seven Red Flags
- Guaranteed returns — "double your Bitcoin," "guaranteed 10% a month." No real investment guarantees returns. This one alone is enough to walk away.
- Urgency and deadlines — "offer ends tonight," "only 3 spots left." Urgency exists to stop you thinking. Legitimate opportunities survive you sleeping on them.
- Unsolicited contact — a stranger messaging you about an investment, a "support agent" DMing you first, a romance that turns to crypto tips. Real platforms don't cold-DM you returns.
- Asking you to send first — "send 0.1 to verify and we'll release your winnings," or any "pay a fee to unlock a bigger amount." Money flowing from you to unlock money is always the scam.
- Fake endorsements — a celebrity "giveaway," a cloned exchange site, a famous name attached to a token. Verify on the real, official channel, never the link you were sent.
- Connect-your-wallet traps — a site asking you to approve a transaction or sign a message to "claim" or "verify." A malicious approval can drain your wallet in one click.
- Pressure against checking — "don't tell anyone," "your bank won't understand," "ignore the warning." Anyone discouraging you from verifying is the reason to verify.
One flag is enough — you don't need to collect the set
You don't have to confirm a scam to walk away from one. A single red flag — especially "guaranteed returns," "send first," or "hurry" — is sufficient reason to stop. Crypto transactions are irreversible: there is no bank to call, no chargeback, no fraud department to refund you. The 60 seconds you spend recognising a flag is the only protection you get, and it's usually enough.
Before You Click "Approve"
The most modern of these scams — the connect-your-wallet trap — works by getting you to grant a token approval that lets the attacker move your funds. You can check what a contract or token is before you interact with it, and check which approvals you've already granted (and revoke the dangerous ones). For the screening view of a wallet's history, the same public-ledger lens from part 1 applies.
