Nearly every crypto scam ends with you sending funds to an address that cannot be reversed, so the defense that works is to stop at that moment and check three things, who contacted you first, whether you found the platform yourself, and whether the promised return is possible.
The scale is not marginal. The FBI Internet Crime Complaint Center recorded 181,565 complaints with a cryptocurrency nexus in 2025, reporting $11.366 billion in losses, up 22% from 2024, with an average loss of $62,604 and 18,589 people losing more than $100,000 each (source: FBI Internet Crime Complaint Center, 2025 Internet Crime Report). Cryptocurrency investment fraud alone accounted for $7.2 billion and was the single largest source of reported financial losses to Americans that year.

Why crypto is the payment method of choice
Three properties make crypto attractive to fraud operations. Transfers settle without an intermediary who can reverse them, they cross borders in minutes, and an address does not carry a name. A bank wire can sometimes be recalled, and a card payment can be charged back. A confirmed on-chain transfer cannot.
Everything that follows is an attempt to get you to make that one irreversible transfer voluntarily.
Long-running investment scams
The largest category by loss is the relationship-based investment scam, often called pig butchering. The FBI describes these as sophisticated long-term scams using psychological manipulation and the appearance of legitimacy, largely run by organized criminal enterprises based in Southeast Asia that use trafficking victims as forced labor (source: FBI Internet Crime Complaint Center, 2025 Internet Crime Report).
The pattern is consistent. Contact arrives out of the blue by text message, social media, an advertisement, or a dating app, and moves quickly to a private messaging platform. A friendship or romance builds over weeks with no money mentioned. Eventually the contact introduces an investment group or a trading platform, presenting themselves as an insider. Small deposits show impressive gains on a dashboard that the operators control, and small withdrawals are honored to build confidence. Larger deposits follow, sometimes funded by loans the scammer encourages. When you try to withdraw, taxes and fees appear as a final extraction, and then the contact disappears.
Two details make this recognizable early. The platform is always one they introduced rather than one you found. And the profits exist only on their screen, never on a block explorer you can check yourself.
| Scam type | The tell |
|---|---|
| Relationship-based investment fraud | They introduced the platform, and the profits exist only on their dashboard |
| Fake exchange or cloned app | You reached it through a supplied link, or a domain one character off the genuine one, or an app installed outside the official stores |
| Recovery phrase phishing | Anything at all that asks for the phrase |
| Airdrop and approval drainers | A promotional site asks you to sign a transaction that grants a contract permission to move your tokens |
| Impersonation | Support that contacts you first |
| Guaranteed returns | A fixed daily or weekly percentage, which is a payout schedule rather than an investment |
Fake exchanges and cloned apps
Scam platforms are cheap to build and look convincing. Some are entirely fictional. Others clone the branding of a real exchange, sometimes with a domain one character different from the genuine one, and sometimes distributed as an app installed outside the official app stores.
Verify the venue independently. Type the address yourself rather than following a link from a message, check the exchange against an independent directory such as Exchanges, and treat any platform you cannot find through your own search as untrusted. A real exchange has a public licensing footprint, a support channel that predates your conversation, and withdrawal terms it will state before you deposit.
Anything that asks for your recovery phrase
Your seed phrase is the wallet. Anyone who reads it can move your funds without you. There is no legitimate reason to give it to a support agent, enter it on a website, type it into a form to claim a reward, or share it to "verify" or "synchronize" a wallet.
phishing pages that harvest recovery phrases are the most direct attack in crypto, and they usually arrive with time pressure attached: an account is compromised, a migration is required, a claim window closes tonight.
Airdrop and approval drainers
A subtler version does not ask for your phrase at all. You are invited to claim an airdrop, mint a token, or connect a wallet to a promotional site. The site asks you to sign a transaction, and the transaction grants a smart contract permission to move tokens out of your wallet. Nothing looks stolen at the moment of signing, and the wallet is drained later.
Read what you are signing rather than the page you are signing on. A hardware device that displays transaction details on its own screen helps here, because it shows what the transaction actually does rather than what the website claims. Periodically review and revoke token approvals you no longer use.
Impersonation
Scammers pose as exchange support staff, wallet manufacturers, government agencies, well-known founders, and, increasingly, as recovery services. The FBI notes that victims of investment fraud are subsequently targeted by recovery scams that claim to help retrieve lost funds (source: FBI Internet Crime Complaint Center, 2025 Internet Crime Report). Losing money once puts you on a list.
Support that contacts you first is the reliable tell. Real support responds to tickets you opened, through channels you reached from the company's own site, and does not initiate contact by direct message. No legitimate agency or exchange asks to be paid in crypto to release your funds.
Guaranteed returns
Fixed, guaranteed, high returns are not a product that exists. yield farming and staking pay variable rates that come from real activity, and any headline apy moves with that activity and carries a risk of loss. A pitch quoting a guaranteed daily or weekly percentage is describing a payout schedule, not an investment, and payouts to early participants are usually funded by later ones.
Treat the same skepticism toward tokens promoted with a launch deadline and a promise of a listing. A rug pull takes the money raised and abandons the project, and it is common among newly launched tokens on decentralized venues where anyone can create a market.
Checks to run before you send
- Ask who initiated contact. Distrust anything that began with an unsolicited message.
- Confirm you found the platform independently. Not through a link someone sent.
- Look for the exchange in a licensing register or an independent directory before depositing. Start from a known asset and jurisdiction, which is what Where to buy and Bitcoin are for.
- Verify claimed balances on a public block explorer, not on the counterparty's dashboard.
- Send a small test transfer first when moving funds to any new address.
Moving assets into your own custody removes an entire class of these risks, and the mechanics are covered in Move crypto off exchange.
If you have already sent funds
- Stop paying immediately, including any fee or tax demanded to release a withdrawal. Those demands are the final stage of the scam, not a route out of it.
- Record everything. Transaction hashes, addresses, screenshots, the platform's domain, and the accounts that contacted you.
- Report it to your national reporting body, which in the United States is the FBI Internet Crime Complaint Center, and to your bank if funds left through it.
- Notify the exchange you withdrew from. Some can flag or freeze on-platform destinations.
Frequently Asked Questions
Can a crypto transaction be reversed once it is confirmed?
No. Confirmed on-chain transfers are final by design. Recovery, when it happens at all, comes from law enforcement freezing assets at a regulated exchange, not from undoing the transaction.
How do I check whether an exchange is real?
Look for it in the regulator's licensing register for your jurisdiction and in an independent directory such as Exchanges. Reach the site through your own search rather than a supplied link, and be careful of near-identical domain names.
Someone I have known online for months is offering trading advice. Is that different?
Not necessarily. The relationship-building phase of these scams runs for weeks or months before money is mentioned, which is exactly what makes them effective. The test is not how long you have talked but whether they introduced the platform and whether the returns can be verified independently.
Is a small test transfer worth the fee?
Almost always. A test transfer of a few dollars confirms the address, the network, and the recipient before you commit the full amount, and it costs a fraction of a single mistake.
