Crypto Scams: How to Spot Pig Butchering, Fake Exchanges and Rug Pulls

Most crypto scams are not technically sophisticated. They are old cons, such as fake investments, romance fraud and impersonation, adapted to a payment method that is fast, global and usually irreversible. The FBI's Internet Crime Complaint Center reports that investment fraud involving cryptocurrency is among the costliest categories of losses Americans report each year, and its annual Internet Crime Report at ic3.gov publishes the latest figures.

The good news is that these schemes follow recognizable scripts. Knowing the main ones, and the warning signs they share, is the most effective protection there is.

Why crypto is a favorite tool for fraudsters

Scammers prefer crypto for practical reasons:

• Transfers are hard to reverse. Unlike a card payment, there is generally no chargeback once coins leave your wallet.
• Money moves fast and across borders. Funds can be split and shuffled through many wallets in minutes.
• The technology is unfamiliar. Jargon makes it easier to fake a convincing-looking platform or "opportunity."
• Hype provides cover. Stories of overnight gains make unrealistic promises sound plausible.

None of this means crypto itself is a scam. It means the usual protections of the banking system are often missing, so the burden of caution shifts to you. Our explainer on crypto wallets and custody covers how holding coins differs from holding money at a bank.

Pig butchering: the long con

"Pig butchering" is the name, taken from the scammers' own slang, for a scheme that "fattens up" a victim before taking everything. Federal agencies also describe it as a relationship investment scam.

It usually unfolds in stages:

1. First contact. A stranger reaches out by text, a dating app, social media or a "wrong number" message, then keeps chatting in a friendly way.
2. Building trust. Over weeks, the contact becomes a friend or romantic interest, often sharing photos and stories of a successful lifestyle.
3. The opportunity. They mention making money trading crypto and offer to show you how, on a specific app or website.
4. Early wins. Your account on the platform shows impressive gains, and you may even be allowed to withdraw a small amount, which builds confidence.
5. The squeeze. You are encouraged to invest more, sometimes borrowing or draining retirement savings. When you try to withdraw a large sum, you are told to pay "taxes," "fees" or a "deposit" first. The money never comes back.

The gains are fiction. The platform is controlled by the scammers, and the balance on screen is just a number they display.

Fake exchanges and trading platforms

Many scams rely on websites or apps that imitate real trading platforms. They can look polished, with charts, live prices and customer support chat. Some copy the branding of legitimate companies with slightly altered web addresses.

Warning signs include a platform you only heard about from a new online contact, an address that differs subtly from the real company's, pressure to deposit through crypto ATMs or wire transfers, and withdrawal problems that can only be "solved" by sending more money.

Rug pulls and pump-and-dumps

In the more speculative corners of crypto, the risk often comes from the project itself.

• Rug pull: developers launch a new token or project, attract buyers with hype, then abandon it and drain the funds, leaving holders with worthless tokens.
• Pump-and-dump: promoters accumulate a little-known token, hype it through social media or group chats to push the price up, then sell to the latecomers.

These schemes often feature anonymous teams, aggressive influencer promotion, countdown timers and claims that "this is the next big coin." The SEC and CFTC have both brought actions in cases they allege involved fraudulent token offerings or market manipulation.

Impersonation, giveaways and recovery scams

A few more scripts come up again and again:

• Impersonation: someone posing as a government agency, a bank, tech support or a well-known company says your account is compromised and tells you to move money into crypto "for safekeeping." Real agencies and banks do not do this.
• Giveaway scams: fake posts or videos promise to double any crypto you send. No legitimate giveaway asks you to send money first.
• Blackmail and extortion: emails claim to have compromising information and demand payment in bitcoin.
• Recovery scams: after a loss, someone offers to trace and recover your money for an upfront fee. Victims of one scam are frequently targeted again this way.

Common scams at a glance

The red flags they share

Across every variation, the same signals appear:

• Guaranteed or unusually high returns with little or no risk.
• Urgency, such as limited-time offers or warnings that your account will be frozen.
• Secrecy, including requests not to tell family or your bank.
• Unusual payment methods, especially crypto ATMs, gift cards or wire transfers to individuals.
• Withdrawal obstacles that can only be cleared by sending more money.
• Unverifiable people and platforms you cannot look up independently.

A useful rule of thumb from regulators: anyone who asks you to pay only in crypto, or promises returns with no risk, is a strong signal of fraud.

What to do if you think you have been scammed

Act quickly, even if you feel embarrassed. Scammers rely on silence.

1. Stop sending money and stop engaging with the contact.
2. Gather records, including wallet addresses, transaction IDs, website addresses, usernames and messages.
3. Contact the exchange or bank you used to send the funds and ask whether anything can be frozen.
4. Report to the FBI at ic3.gov, which is the main federal channel for internet fraud.
5. Report to the FTC at ReportFraud.ftc.gov.
6. Submit a tip to the SEC at sec.gov/tcr or to the CFTC if an investment offer was involved, and consider notifying your state securities regulator or attorney general.
7. Secure your accounts by changing passwords and turning on two-factor authentication if any logins were shared.

A habit worth building

The single most protective habit is to separate where you heard about an opportunity from where you check it. Look up platforms and people yourself, not through links you were sent, and talk any investment over with someone you trust before money moves. Crypto can be a legitimate asset to own, but no legitimate investment depends on speed, secrecy or a stranger's coaching.
