Weiyi AI Collapse and Transition to Miyi Exchange: A Secondary Harvest After AI Quantitative Matrix Ponzi Scheme

Who Gets Targeted

The victims are primarily middle-aged and young people in third- and fourth-tier cities, alongside some retired elderly individuals. They generally lack foundational knowledge of virtual currencies and AI, yet are attracted by pitches such as 'AI automated arbitrage' and 'daily fixed returns.' Most of them encountered the project through WeChat groups and short-video platforms, starting with small test investments of several thousand yuan before gradually increasing their stakes. Their psychological vulnerabilities center on the fear of missing out (FOMO) and blind trust in group 'mentors.' Driven by profit screenshots from older users and 'capital-guaranteed promises,' they ignored where their funds were going and the exit mechanism until the platform collapsed or their migrated assets were frozen, realizing too late that they had been scammed. Some fell into debt crises due to borrowing money to invest.

骗局怎么运作

• Disguised as a High-Yield AI Quantitative Platform: Weiyi AI claimed to possess an AI matrix quantitative trading system capable of automatically capturing price differences in Bitcoin and other virtual currencies for stable daily profits. It fabricated profit curves and user profit screenshots in the backend, running ads on WeChat groups and short-video platforms to attract users to register and recharge USDT or fiat currency.
• Small-Scale Trial and Profit Baiting: New users initially recharged hundreds to thousands of yuan. The platform cashed out the so-called 'AI returns' on a daily or weekly basis, allowing small withdrawals to create the illusion of real earnings and inducing users to increase their investments. Customer service emphasized pitches like 'AI is smarter than humans; you can profit without understanding crypto.'
• Refinancing Old Users with New Funds to Maintain Payouts: Older users' continuous withdrawals relied on new users constantly recharging. The platform was connected to no real exchange or quantitative system; all funds went into private wallets or underground channels. By establishing a 'profit calendar' and 'tiered commission rebates' to recruit people, it maintained surface-level payouts.
• Transitioning to Miyi Exchange After Collapse: When incoming funds became insufficient to cover older users' withdrawals, the platform froze Weiyi AI accounts under the guise of 'technical upgrades' and 'compliant migration,' guiding users to migrate their assets to the Miyi Exchange while demanding additional 'activation fees' or 'risk margin deposits' to unlock them, actually entering the secondary harvest phase.
• Fund Transfer and Disappearance: Once the secondary harvest was complete, the operators shut down customer service, disbanded communities, and cleared the website. Funds were laundered through mixers or underground exchanges, leaving victimized users unable to withdraw funds. Panic spread in rights-defense groups, and after some accounts were kicked out, the operators became completely unreachable.

红旗信号（看到这些快跑）

• 🚩 Claiming fully automated AI arbitrage with daily fixed returns exceeding 1%, far outstripping legitimate financial market returns.
• 🚩 Mandating USDT or private transfers for deposits, without providing bank escrow vouchers or third-party fund custody proof.
• 🚩 The platform website has no filing (ICP record) or its filing entity is an offshore shell company, lacking any real transaction records or audit reports.
• 🚩 Promotion relies on WeChat groups and short-video private domains, using pitches like 'mentor-led trading' and 'earning over ten thousand yuan a month with zero baseline knowledge' to recruit newcomers.
• 🚩 Demanding under the pretext of 'technical upgrades' or 'compliant migration' that users transfer their assets to another unfamiliar platform and pay fees again.

真实案例

• In August 2026, according to anti-fraud network disclosures, about 300,000 people were trapped after Weiyi AI collapsed, with the involved amount reaching billions of yuan. The platform triggered mass police reports across multiple regions by migrating to the Miyi Exchange and demanding reactivation fees again.
• In June 2026, a victim reported on a public complaint platform that after investing about 120,000 yuan into Weiyi AI, daily returns seemed normal, but withdrawals were consistently delayed. Eventually, the platform changed its tune, demanding a transfer to the Miyi Exchange and an additional 8,000 yuan in handling fees, freezing all assets.
• In August 2026, Sina Finance reprinted a Jinyun report: Zhangmouli in Tongxu County, Henan Province, used high profits from AI smart stock trading as a pretext to attract more than a dozen people to invest, returning 2,500 yuan in rewards for every 10,000 yuan invested. In June 2025, the involved app became inaccessible, and the amount involved for more than ten people reached around one million yuan. The Tongxu County Public Security Bureau opened a contract fraud case, with no progress for over a year.

• In March 2026, project resource websites solid-exposed that Weiyi AI (Microex) completely collapsed: accumulating over 300,000 members and pocketing billions in funds. Multiple team leaders were arrested by the police and placed under criminal investigation, and the so-called migration to Miyi Exchange was actually a secondary harvest.

Official Stance

• In August 2026, public security anti-fraud centers in multiple regions issued early warnings, explicitly naming Weiyi AI and Miyi Exchange as virtual currency Ponzi schemes and reminding the public not to participate in so-called AI quantitative matrix investments.
• In July 2026, the National Anti-Fraud Center pushed AI investment fraud reminders on official platforms, clearly defining 'refinancing old with new + asset migration' as a typical secondary harvest tactic.
• In September 2026, the National Internet Finance Association of China issued risk warnings pointing out that unregistered AI virtual currency trading platforms carry extremely high fund security risks.

How to Protect Yourself

• ✅ Reject any virtual currency project promising 'AI automated arbitrage' or 'daily returns over 1%', and do not consider high-interest rebates at all.
• ✅ Demand that platforms present compliant licenses, third-party fund custody agreements, and audit reports. Block them immediately if they lack proof.
• ✅ Conduct investments only through regular exchanges with real-name registration, and do not transfer funds to private wallets or unknown accounts.
• ✅ Immediately stop operations and preserve evidence upon encountering requests such as 'asset migration' or 'paying activation fees again.'
• ✅ Join anti-fraud prevention groups or follow public security anti-fraud accounts. Consult the police or financial regulators first when facing uncertain projects, and do not trust 'mentors' in groups.
