Global cryptocurrency fraud losses exceeded $10 billion in 2025, and 2026 is on track to surpass that figure. Despite growing public awareness, scam operations have become increasingly sophisticated using AI-generated personas, professional-looking platforms, and long-term trust-building strategies that make them nearly indistinguishable from legitimate services.
Based on our casework and data from the FBI IC3, Action Fraud, and Chainalysis, these are the five scam types responsible for the vast majority of crypto losses.
1. Pig-Butchering Scams (Sha Zhu Pan)
Pig-butchering is currently the world's most damaging form of crypto fraud. The name comes from the Chinese expression for "fattening a pig before slaughter" the scammer builds a relationship with the victim over weeks or months, nurturing trust before ultimately defrauding them of everything.
These scams typically begin on dating apps, LinkedIn, WhatsApp, or random "wrong number" texts. The scammer often operating from Southeast Asian fraud compounds maintains a romantic or friendly relationship, then gradually introduces the victim to a cryptocurrency "investment opportunity." They show fabricated returns, allow small withdrawals to build trust, and encourage the victim to invest larger and larger amounts. When the victim tries to withdraw significant funds, they are told they must pay "taxes" or "fees" first. The scammer then vanishes.
Warning signs: An online contact you've never met who pushes crypto investments; platforms you cannot find through independent Google searches; "exclusive" investment opportunities; requests to move funds to an unfamiliar platform.
2. Fake Cryptocurrency Exchanges and Trading Platforms
Fraudulent trading platforms are built to look identical to legitimate exchanges complete with live price charts, transaction histories, support chat, and professional branding. Victims deposit real funds, which appear on the platform as crypto balances, but the platform is entirely controlled by the scammers. No real trading ever occurs.
These platforms often appear through Google ads, social media promotions, or influencer endorsements (many of which are fabricated). They allow small initial withdrawals to appear legitimate before encouraging larger deposits. When victims attempt to withdraw substantial amounts, they encounter endless "verification," "upgrade fee," or "tax clearance" requirements.
Warning signs: Platforms not listed on CoinMarketCap or CoinGecko; no information about company registration or regulatory status; unsolicited investment invitations; guaranteed profit percentages.
3. Ponzi and High-Yield Investment Schemes
Crypto Ponzi schemes promise extraordinary fixed returns often 1�5% per day funded by new investor deposits rather than actual trading profits. Early investors receive genuine payouts (funded by later investors), creating apparent legitimacy before the operation collapses and founders disappear with remaining funds.
These schemes are often promoted via YouTube, Telegram, and Discord communities, with "proof" of returns and testimonials from earlier investors who genuinely did receive payments. The collapse is sudden and total often triggered when withdrawal requests exceed new deposits.
Warning signs: Guaranteed daily or weekly returns; referral commissions for recruiting new members; pressure to reinvest profits; inability to independently verify the platform's trading activity.
✅ No legitimate investment can guarantee fixed returns in cryptocurrency markets. Anyone promising consistent profits regardless of market conditions is operating a fraud.
4. Rug Pulls and DeFi Token Scams
In decentralised finance (DeFi), "rug pulls" occur when developers create a new cryptocurrency token, generate hype and investment, then drain the liquidity pool and abandon the project. The token's value collapses to zero overnight, leaving investors with worthless holdings.
Rug pulls have become increasingly professional complete with audited-looking smart contracts, celebrity endorsements (often fabricated), and active community Discord servers. Some run for months before the developers extract funds. The 2026 rise of AI-generated code has made fraudulent tokens easier to create and harder to distinguish from legitimate projects.
Warning signs: Anonymous development teams; smart contracts that cannot be independently audited; tokens only tradeable on obscure DEX platforms; liquidity not locked; aggressive social media promotion with urgency tactics.
5. Impersonation Fraud and Fake Customer Support
Scammers impersonate officials from legitimate cryptocurrency exchanges (Coinbase, Binance, Kraken), government agencies (HMRC, IRS, FCA), or even law enforcement, claiming there is a problem with the victim's account that requires immediate action.
Victims are directed to "secure" their funds by transferring them to a "safety wallet" (controlled by the scammer), or are convinced to provide seed phrases, private keys, or remote access to their device. Real exchanges and government agencies will never ask for any of these things.
Warning signs: Unsolicited contact claiming to be from an exchange or authority; requests for seed phrases, private keys, or passwords; urgency and threats of account closure or legal action; instructions to download remote access software.
