On June 7th, the Investigation Police Agency of Dong Nai Province’s Public Security initiated legal proceedings and detained five individuals, including Nguyen Quoc Hung (41 years old) and Bui Thi Thanh Nga (34 years old), both from Hanoi; Ho Long Tri (45 years old) from Ho Chi Minh City; Dinh Huu Hay (34 years old) from Binh Dinh Province; and Than Van Hiep (43 years old) from Trang Dai Ward, Bien Hoa City. They are being investigated for fraud and appropriation of property.
The accused individuals
According to the investigation, since February 2023, Hung and Nga had hired people to develop the Matrix Chaine cryptocurrency project, based on the “SafePal” e-wallet platform. They then built a network of investors with the intention of defrauding them.
To execute their scheme, Hung and Nga enlisted the help of Tri, Hay, and Hiep, who acted as their subordinates.
Cars seized during the investigation
When investors transferred money to participate, Hung handed control over to Nga. Of the funds received, Hung and Nga allocated approximately 40% to regional leaders, 5% to promoting the Matrix Chaine cryptocurrency and event expenses, and kept the remaining 55% for their personal use.
Law enforcement determined that through these schemes, the group attracted tens of thousands of participants, with over 138,000 registered accounts and a total investment of 394 million USD (equivalent to more than 10 trillion VND). The accused individuals appropriated thousands of billions of VND from this amount and invested it in real estate and luxury cars.
In May 2025, Dong Nai Provincial Police coordinated with the Criminal Police Department of the Ministry of Public Security, as well as public security units in Hanoi, Ho Chi Minh City, Hung Yen, Binh Dinh, Dak Lak, Gia Lai, Bac Giang, and other provinces to establish multiple task forces. These task forces simultaneously took action, arresting and searching the residences and workplaces of the accused, seizing various objects and evidence related to the case. The investigation is ongoing, and the police are expanding their investigation.
