Long-con romance-investment fraud targeting Vietnamese users through Zalo, Facebook, and Telegram with fake crypto trading platforms.
Part of: Pig-Butchering Scams
Last reviewed: 1 June 2026
Vietnam is both a major target country for pig-butchering scams and, according to law enforcement reports, the source of some scam operations targeting the Vietnamese diaspora abroad. The Ministry of Public Security (Bộ Công an) has issued repeated national warnings about investment fraud of this type, particularly affecting young urban professionals in Hanoi, Ho Chi Minh City, and Da Nang.
Fraudsters approach victims through Zalo (Vietnam's dominant messaging app), Facebook, and dating apps. They build trust through cultural familiarity — discussing Vietnamese food, holidays, and family values — before steering the relationship toward investment.
How this scam works on Vietnam
Contact begins as a friendly Zalo message or Facebook comment interaction. The fraudster cultivates an emotional connection over several weeks, frequently mentioning their own investment success on a particular platform. They offer to guide the victim through a few 'beginner' trades to get started.
Victims are directed to a polished platform that mimics licensed Vietnamese exchanges or major international names. The platform interface shows consistent profits. When the victim tries to withdraw larger sums, they are told a '10% prepayment of capital gains tax per Thông tư [tax circular]' must be paid before withdrawal is authorized — an entirely fabricated requirement.
Vietnam's large overseas worker population (workers sending remittances from Japan, Korea, Taiwan) is also targeted through community Facebook groups with investment offers framed as ways to grow remittances before sending them home.
Common red flags
- Unsolicited Zalo or Facebook message that rapidly becomes warm and personal
- New friend who mentions impressive investment returns soon after meeting online
- Platform not registered with SSC (Ủy ban Chứng khoán Nhà nước) or SBV (Ngân hàng Nhà nước)
- Demand for 'capital gains tax' prepayment before withdrawal — not a real Vietnamese tax mechanism
- All communication occurs exclusively on Zalo or Telegram, never by verifiable business channels
- Urgency pressure to invest before a 'market window' closes
How to protect yourself
- Check any investment platform against SSC's authorized securities company registry at ssc.gov.vn
- Verify cryptocurrency platforms with SBV guidance — crypto trading is in a legal grey zone and SBV does not license crypto exchanges
- Report suspicious contacts to the Ministry of Public Security cybercrime portal at canhbaolua.vn
- Consult with a family member or trusted financial professional before sending any funds to an online contact
- Do not let urgency pressure override due diligence
How to report it
- Report to the Ministry of Public Security cybercrime portal at canhbaolua.vn
- Contact local police (Công an) at the provincial level
- Report fraudulent investment promotions to SSC at ssc.gov.vn
Frequently asked questions
Is cryptocurrency trading legal in Vietnam?
As of this guide's review date, Vietnam does not have a comprehensive legal framework for cryptocurrency. SBV does not recognize crypto as a legal payment method, and there are no licensed crypto exchanges. This legal ambiguity is exploited by fraudsters who position their platforms as operating in a permissible space.
