Vietnamese police arrested four suspects accused of running a fraudulent ‘BitMiner’ crypto‑mining investment site that reportedly stole about 4 billion dong from over 200 investors. Authorities said the scheme advertised Dubai operations and unrealistic returns and seized devices as part of a broader regional crackdown on crypto fraud.

Vietnamese authorities have detained four individuals alleged to have operated a fraudulent cryptocurrency mining investment platform known as ‘BitMiner’, according to reporting by Cointelegraph. Investigators say the scheme lured more than 200 victims with promises of Dubai‑based mining operations and high, unrealistic returns, ultimately siphoning roughly 4 billion dong, equivalent to about $157,000. Police secured digital devices, accounts, and financial records during raids and have launched a formal criminal probe into allegations of fraud and money laundering. Officials noted the scam’s structure involved recruitment of investors, staged documentation to imply legitimacy, and rapid conversion or movement of proceeds that complicated victim recovery. The arrests form part of a coordinated regional effort to clamp down on online crypto fraud, where jurisdictions are increasingly prioritising cross‑border cooperation and forensic cryptocurrency tracing. Authorities urged investors to be cautious of guaranteed returns, to verify operational claims and corporate registrations, and to report suspected scams promptly to improve chances of asset recovery and successful prosecutions.
