Pig butchering
Also known as: romance baiting, cryptocurrency investment fraud, sha zhu pan
How it works
A friendly or flirtatious contact – often on a dating app, social media or a 'wrong number' text – builds a relationship and casually mentions success trading crypto, gold or forex as a 'side job'. They coach the victim to open an account on a professional-looking but fake trading platform or app, which shows growing fake profits and may offer loans to encourage larger investments. The victim is encouraged to invest more, sometimes taking loans or cashing out retirement savings. When they try to withdraw, they are told to pay 'taxes' or 'fees' first, then the scammers disappear. The FBI says these scams are largely run by organised crime groups in Southeast Asia using trafficked people as forced labour.
Red flags
- A new match brings up how much money they make trading crypto, gold or forex
- They offer to teach you or have an 'uncle/mentor' with insider knowledge
- They send a link to a trading platform or app you have never heard of
- The platform shows fast, steady profits but withdrawals need a 'tax', 'fee' or 'deposit' first
- They pressure you to invest more, borrow, or use retirement savings
- They claim they were hurt by an ex who wanted their money (a scripted backstory)

If it is happening to you
- Do not deposit more money, and do not pay any 'tax', 'fee' or 'unlock' charge to withdraw – it is part of the scam.
- Stop contact with the match and anyone they introduced (mentors, 'customer service').
- Contact your bank and the legitimate crypto exchange you used immediately; record wallet addresses, transaction IDs and website URLs.
- Report to the authorities below. Expect follow-up 'recovery' offers to be scams too.
Where to report
Related scams

Romance scams
A scammer builds an online relationship using a fake or borrowed identity, often over weeks or months, and invests heavily in attention and affection.

Sextortion and image blackmail
The criminal poses as an attractive person (often a young woman) on a dating app, social media or game, flirts quickly, and persuades the target to exchange nude images or join an intimate video call that is secretly recorded.

Catfishing and impersonation
Scammers build profiles from photos stolen from real people – often soldiers, professionals or celebrities – and invent a life that explains why they cannot meet: deployed overseas, working on an oil rig, with an international organisation, or too famous.
