Crypto scams have been around as long as crypto. The specific scams change — pig butchering, fake exchanges, rug pulls, deepfake celebrity videos — but the underlying patterns have been consistent for a decade. If you can spot the patterns, you can ignore 90% of what's coming at you.
Here are the seven red flags that have outlasted every iteration of scam.
1. "Guaranteed returns" — any number, any rate, any duration
There is no such thing as a guaranteed return in crypto. There is no such thing as a guaranteed return in any investment. Anyone promising specific returns — "10% per week," "double your money in 30 days," "stable 2% daily" — is running a Ponzi scheme. The math doesn't work any other way.
The polish doesn't matter. The website can be beautiful. The CEO can be on a podcast. The whitepaper can be 80 pages of formulas. If the promise is guaranteed returns, it's a scam.
2. Urgency manufactured by a stranger
Real opportunities don't come with a 24-hour clock attached. If someone you don't know is telling you that you have to send crypto right now or you'll miss out — on a token launch, on a "special" allocation, on a "limited" pool — they are running a known scam pattern.
Legitimate financial decisions don't get worse if you wait a day to think about them. Scam ones do, because the scammer needs you to act before you check.
3. "You owe taxes/fees/processing" to receive money
A common end-stage scam: you've supposedly won, earned, or are receiving crypto. To "release" it, you just need to pay a small fee. Then another. Then one more.
No legitimate crypto transaction works this way. If you genuinely have crypto to receive, you don't pay to receive it — the sender pays the network fee out of their funds, not yours.
The variant: "your wallet is locked, send X to unlock it." Wallets don't get locked by external parties. If your own wallet seems locked, it's malware on your device, not a missing fee.
4. The "rich friend" / "trader mentor" on social media
You're scrolling Instagram, X, TikTok. A stranger DMs you about their amazing trading returns, screenshots, lifestyle photos. They want to mentor you, or invite you to a "VIP group," or show you their "system."
This is "pig butchering." The grooming phase can last weeks. The scammer builds trust, gets you to deposit on a fake trading platform, lets you "withdraw" a small amount to prove it's real, then convinces you to put in everything you have. The platform is fake. The withdrawal feature stops working. The mentor disappears.
The defining red flag: someone with no prior relationship to you, contacting you out of the blue with a profitable opportunity. Block immediately.
5. Celebrity endorsements that require you to send crypto first
You see a video of Elon Musk, or some other famous person, promoting a "doubling" giveaway — send 1 BTC, get 2 BTC back. Or a token launch. Or a charity drive that requires a deposit.
The videos are sometimes deepfaked, sometimes recycled from old clips, occasionally even appear on hacked legitimate accounts. The pattern is always the same: send crypto first, "receive" more later. You never receive anything.
Real celebrities don't run crypto giveaways that require deposits. Real charities accept donations one-way; they don't pay you back.
6. Websites that almost match a real exchange's URL
Phishing exchanges are a major scam vector. The site looks identical to Coinbase, Kraken, Binance — but the URL has a subtle change. "coinbasee.com". "kraken-secure.com". "binance.io.scam-domain.com".
You log in. The fake site captures your password and 2FA. They drain the real account.
Defense: bookmark the official URL. Never click a link in an email or DM to "log in." Type the URL by hand for important sites. If you're not sure, check the URL bar character by character before typing your password.
7. The opportunity that requires you to ignore obvious warnings
If your bank flags the transaction. If the exchange asks you a security question and the answer makes you nervous. If your spouse / friend / accountant says it sounds wrong. If a search for the platform name plus the word "scam" returns multiple results.
These are not bureaucratic obstacles. They are people and systems trained to catch fraud, and they're catching yours. Real opportunities don't trip every single one of them.
The bottom line
The specific scams will keep changing. The underlying patterns won't. The shortest summary you can carry:
- No guaranteed returns
- No urgent deadlines from strangers
- No paying to receive money
- No DMs from "rich" strangers offering mentorship
- No celebrity videos requiring deposits
- No clicking links to "log in"
- No ignoring obvious warnings
If you'd like one rule that catches almost everything: anyone you didn't seek out, asking you to send crypto, is running a scam. The exceptions are vanishingly rare.
None of this is financial advice. It's pattern recognition. The patterns are real and stable. Use them.
