Authorities in Vietnam have dismantled a large-scale cryptocurrency fraud operation, arresting five suspects accused of defrauding over 138,000 investors out of nearly $394 million. The scam, orchestrated by the Matrix Chain (MTC) platform, involved a multi-level pyramid scheme that promised unrealistic returns and ultimately left victims financially devastated. The Vietnamese Ministry of Public Security has shut down the fraudulent platform and is working to recover assets. 2025’s early crypto markets were shaken by this case. Experts have pointed to the Matrix Chain scam as evidence of the challenges in protecting investors from elaborate scams exploiting the rapid growth of decentralized finance.
