Summary: Crypto scams cost victims billions of dollars every year, ranging from fake giveaways and crypto romance scams to phishing sites, crypto ATM scams and rug pulls. This guide gives you a full crypto scams list, the red flags that give them away, the biggest crypto scams in history, and practical steps on how to avoid crypto scams when buying, trading, or spending cryptocurrency.
What Are Crypto Scams?
A crypto scam is any scheme designed to trick someone into handing over cryptocurrency, private keys, or personal information under false pretenses. Because crypto transactions are irreversible and often pseudonymous, scammers favor it as a payout method. Once funds leave a victim's wallet, there is usually no bank or company to call for a reversal, which makes prevention far more effective than recovery.
The Federal Trade Commission tracks these patterns closely and publishes updated guidance on common tactics and warning signs.
Crypto Scams List: The 10 Most Common Types
This crypto scams list covers the schemes behind most losses. Each one is explained in more detail below.
| Scam type | How it works | Biggest red flag |
|---|---|---|
| Phishing | Fake sites and apps steal your seed phrase or login | A link you did not go looking for |
| Giveaway and impersonation | Fake celebrities promise to double your crypto | Send first to receive more |
| Romance and pig butchering | A fake partner pushes a fake trading platform | Investment advice from someone you met online |
| Rug pulls and fake tokens | Developers drain liquidity and vanish | Anonymous team, hype, no track record |
| Ponzi schemes | Old investors are paid with new deposits | Guaranteed high returns |
| Airdrop scams | Fake free tokens lead to wallet-draining approvals | A token you never asked for |
| Telegram scams | Fake support, groups and pump signals | Admins messaging you first |
| Crypto ATM scams | Callers pressure you to deposit cash at a Bitcoin ATM | Anyone telling you to pay by ATM |
| AI scams | Deepfake videos and voice clones of real people | A famous face promising returns |
| Recovery scams | Fake experts promise to get your money back | Upfront fees to recover losses |
Use this crypto scams list as a quick check: if an offer matches any row, stop before you send anything.
1. Crypto Phishing Scams
Crypto phishing scams use fake websites, emails, or apps that closely mimic real exchanges or wallets. The goal is to get a victim to enter their seed phrase, private key, or login credentials into a form the scammer controls. From there, the attacker can drain the wallet within minutes.
- Fake exchange login pages sent via email or SMS
- Cloned wallet apps listed in unofficial app stores
- Browser extensions posing as legitimate wallet tools
2. Giveaway and Impersonation Scams
These scams promise to double or multiply any crypto sent to a given address, often impersonating a celebrity, a well known exchange, or even a project founder on social media. No legitimate giveaway ever asks you to send crypto first in order to receive more back.
3. Crypto Romance Scams and Pig Butchering
In crypto romance scams, the fraudster builds a relationship over weeks or months on a dating app or social media before introducing a supposedly lucrative investment opportunity. The victim is guided to a fake trading platform showing fabricated gains, and is encouraged to deposit larger and larger amounts before the platform disappears along with the funds.
4. Rug Pulls and Fake Tokens
A rug pull happens when developers launch a new token, build up hype and liquidity, then withdraw all the funds and abandon the project, leaving the token worthless. These are especially common with new tokens on decentralized exchanges that have little to no track record.
5. Fake Investment and Ponzi Schemes
These schemes promise guaranteed high returns with little or no risk, often paying early investors with money from newer investors to create the appearance of legitimacy. Once new deposits slow down, the scheme collapses and most participants lose their funds.
6. Crypto Airdrop Scams
Crypto airdrop scams start with free tokens that suddenly appear in your wallet, or a post promising a token drop if you connect your wallet. Interacting with the token or the linked site asks you to sign an approval that lets the scammer drain your real assets. Legitimate airdrops never ask for your seed phrase or for a payment, so treat unexpected airdrop crypto scams like phishing: ignore the token and never connect to the site.
7. Telegram Crypto Scams
Telegram crypto scams thrive because anyone can create a group or pose as an admin. Common versions include fake support agents who message you after you post a question, pump-and-dump signal groups, and fake investment bots. Real admins and support teams never message you first, so most crypto scams on Telegram are stopped by that one rule.
8. Crypto ATM Scams
Crypto ATM scams usually start with a call or message from someone posing as a bank, government agency or tech support. They claim your money is at risk and tell you to withdraw cash and deposit it into a Bitcoin ATM, often scanning a QR code they send you. No legitimate organisation ever asks you to pay by crypto ATM, which makes this one of the easiest crypto ATM scams to recognise once you know the pattern.
9. AI Crypto Scams
AI crypto scams use deepfake videos of celebrities and executives, cloned voices on phone calls, and AI-written messages that sound convincingly human. A video of a well-known figure promoting a giveaway or trading platform is almost certainly fake. Because AI crypto scams look and sound real, verify any offer through the person’s or company’s official channels before acting.
10. Crypto Recovery Scams
Crypto recovery scams target people who have already lost money. Fake recovery agents, lawyers or “blockchain investigators” promise to trace and return stolen funds in exchange for an upfront fee, then disappear. Legitimate law enforcement does not charge victims, so any crypto recovery scams pitch that asks for payment first is a second scam.
Biggest Crypto Scams in History
The biggest crypto scams show how the same tactics scale up to billions of dollars:
- OneCoin: a fake cryptocurrency sold through multi-level marketing from 2014, which took in an estimated $4 billion. Its founder, Ruja Ignatova, disappeared in 2017.
- BitConnect: a lending platform that promised daily returns and collapsed in 2018, one of the most notorious Ponzi schemes in crypto.
- PlusToken: a wallet and investment scheme that drew in billions of dollars, mainly in Asia, before collapsing in 2019.
- FTX: the exchange that collapsed in 2022 after customer funds were misused. Founder Sam Bankman-Fried was convicted of fraud in 2023.
What the biggest crypto scams have in common is promised returns that could not be real, and trust in a person or brand standing in for proof.
Bitcoin Scams: Is Bitcoin a Scam?
No. Asking “is Bitcoin a scam” is reasonable given how many frauds use its name, but Bitcoin itself is an open network that has run since 2009 with no company or person controlling it. A Bitcoin scam is a scheme that uses Bitcoin as bait or as the payment method, not a flaw in Bitcoin.
New tokens that borrow Bitcoin’s name deserve extra care. Bitcoin Hyper (HYPER), a heavily advertised presale token marketed as a Bitcoin layer 2, is a common example: reviews disagree on whether it is legitimate, its team is anonymous, and copycat sites impersonating its presale have been flagged as phishing. Searches for “bitcoin hyper legitimacy scam warnings” reflect that uncertainty. Whatever the project, check for a public team, working code and independent audits before buying, and only use the official site.
How to Spot Crypto Scams: Red Flags to Watch For
Most crypto scams share a handful of warning signs. Recognizing these patterns early is the single best way to avoid losing funds.
- Guaranteed or unusually high returns with little to no explanation of how they are generated
- Pressure to act fast, such as a limited time offer or countdown timer
- Requests to send crypto first before receiving a prize, refund, or larger payout
- Unsolicited contact from someone claiming to be support staff, a celebrity, or a romantic interest
- Requests for your seed phrase or private keys, which no legitimate service will ever ask for
- Spelling errors, mismatched URLs, or slightly altered domain names on websites and emails
How to Avoid Crypto Scams and Prevent Them
A few consistent habits go a long way toward keeping your crypto safe.
Knowing how to prevent crypto scams comes down to slowing down. Scammers depend on urgency, so a rule of waiting 24 hours before sending crypto to anyone new stops most of them.
- Only download wallet apps and visit exchange sites through official, bookmarked links
- Never share your seed phrase or private keys with anyone, under any circumstance
- Enable two-factor authentication on every exchange and wallet account
- Research a project's team, whitepaper, and audit history before investing
- Be skeptical of unsolicited investment advice, even from people you know online
- Use a hardware wallet for long term storage of significant amounts

A dedicated hardware wallet like Ledger keeps your private keys offline and out of reach of phishing sites and malicious browser extensions.
What to Do If You Have Been Scammed, and How to Report Crypto Scams
If you suspect you have sent crypto to a scammer, act quickly. Move any remaining funds in the affected wallet to a new, secure wallet immediately. Report the incident to the platform involved and to your local authorities or a national fraud reporting agency, since patterns from multiple reports can help investigators track down scam operations. Be cautious of so called recovery services that contact you after a scam, since these are frequently scams themselves targeting victims a second time.
In the United States, incidents can be reported directly to the FTC through ReportFraud.ftc.gov, which shares data with law enforcement partners nationwide.
To report crypto scams in the US, you can also file with the FBI’s Internet Crime Complaint Center (IC3), which tracks crypto fraud nationwide. In the UK, report to Action Fraud. When you report crypto scams, include wallet addresses, transaction IDs, screenshots and the scammer’s usernames, since these help investigators link cases together.

Before You Send Crypto to Anyone
Crypto scams rely on urgency, secrecy, and the promise of easy money. Slowing down, verifying sources independently, and never sharing your private keys or seed phrase will protect you from the vast majority of scams in circulation. When in doubt, treat any unsolicited offer involving crypto as a red flag until proven otherwise, and keep anything you plan to hold offline: get a Trezor hardware wallet with crypto.
