Buong Le Vin Nhan, also known as Eric Buong, is widely recognized as the founder of the ONUS cryptocurrency exchange and the operator of the VNDC Wallet platform. ONUS was developed based on the VNDC Wallet platform founded and run by Buong Le Vin Nhan. Vuong Le Vinh Nhan is the chairman of the board of HVA Investment JSC and a founder and operator of this ecosystem.

As previously reported, many investors have complained that they cannot log in or register new accounts on the ONUS exchange, raising questions about potential legal issues. Recently, HVA, led by Eric Buong, stated on a fan page that outages due to a cloud service provider disrupted system operations, temporarily halting trading and deposits/withdrawals. In a recent interview with Nguyen Lao Dong newspaper, Le Hoai Nya, CEO of the HVA Group, said authorities temporarily seized some equipment to review market-related information, and that HVA had actively cooperated by providing documents upon request. The HVA Group’s CEO emphasized that such seizures are routine operational procedures and that they are fully cooperating to ensure the process remains transparent and thorough.

The ONUS exchange and its associated entities have come under heightened regulatory attention after investors reported login and account registration issues, casting doubt on the platform’s legal standing. The VNDC Wallet-based ONUS platform, developed by entrepreneur Buong Le Vin Nhan and expanded through VNDC.IO, grew to serve more than four million users by 2025, underscoring the scale of the network facing scrutiny.

HVA Group, led by Le Hoai Nya, has publicly stated its cooperation with authorities as part of a broader market information review. In a recent interview, officials explained that some equipment had been temporarily seized to facilitate a transparent and orderly review process, while emphasizing ongoing collaboration with regulators to ensure proper oversight and compliance.
