Vietnam's Ministry of Public Security has announced the dismantling of a major cryptocurrency fraud ring tied to the ONUS ecosystem, resulting in the arrest of seven key suspects. The investigation, which began in earnest on March 23, 2026, led authorities to summon more than 140 individuals for questioning on March 20 and 21 before formally opening a criminal case.
The ministry alleges that the group, led by suspects Vuong Le Vinh Nhan, Tran Quang Chien, and Ngo Thi Thao, created and sold tokens including VNDC, ONUS, and HNG through the ONUS platform. Investigators claim the scheme used misleading promotion, artificial trading activity, and price manipulation to present these tokens as viable investments, attracting users and mobilizing funds estimated to be in the billions of dollars.
Detention orders were issued on March 24, 2026. The suspects now face charges of asset appropriation through electronic networks and money laundering, with activities allegedly dating back to 2018. Authorities have urged potential victims to come forward and issued a public warning against online investment pitches from self-described crypto ecosystems promising high returns.
This case highlights the growing regulatory scrutiny in Vietnam, a nation ranked fourth in the 2025 Global Crypto Adoption Index by Chainalysis. The crackdown underscores official efforts to protect investors in a rapidly expanding yet legally ambiguous market for digital assets.
