AI Cambridge, a purported quantitative trading platform, shut down on March 4th, 2025, with its website going offline. The cambridgeai.xyz domain had been privately registered only a few months earlier, on December 16th, 2024, offering no details about its ownership, executives, or physical address.
The platform's marketing materials appeared primarily in Chinese. This suggested connections to operations based in China or targeting Chinese-speaking populations. AI Cambridge sold no tangible product or service. Its entire business model relied on recruiting new members to invest in the scheme itself.
Participants invested Tether (USDT), a stablecoin, across ten distinct tiers. The entry-level AI-1 tier required 9 USDT for a promised daily return of 1.5 USDT. The highest tier, AI-10, demanded 16,988 USDT, with an advertised daily payout of 4,044.7 USDT. These returns were presented as consistent and predictable.
The compensation plan included referral commissions paid out across three levels. Direct recruits on Level 1 generated a 12% commission for their referrer. Level 2 recruits yielded 2%, and Level 3 recruits provided a 1% commission. Membership itself was free, but participation in the advertised "opportunity" required an initial investment of at least 9 USDT.
AI Cambridge promoted its offering as "quantitative trading." Affiliates downloaded a dedicated application and were instructed to click a button within the app. The higher the investment tier, the more clicks they supposedly needed to perform. Each click, according to the platform, initiated quantitative trading activity, which then generated the shared revenue for investors. This premise was entirely false. Clicking a button in an app does not execute trades in financial markets. The system simply recycled new investor deposits to pay earlier investors, a classic Ponzi scheme structure.
This model resembled a wave of "click a button" app Ponzis that emerged in late 2021. Schemes such as QUA AI Bot, Bytesi, and AQR Quantify all used similar "quantitative trading" narratives before collapsing. Many of these operations last only a few weeks or months before their websites disappear and apps cease functioning, leaving most investors with significant losses. Ponzi mathematics ensures this outcome.
Before a full collapse, participants often found their withdrawal requests locked. Accounts would be frozen, preventing any access to funds. A "recovery scam" frequently followed, where victims were asked to pay an additional fee to "unlock" their disabled funds. These fees were collected, but withdrawals remained impossible, and the scammers stopped responding to inquiries.
These types of fraudulent operations are often traced to scam factories located in Southeast Asia. These facilities are frequently staffed by victims of Chinese human trafficking networks. In September 2024, the U.S. Treasury Department sanctioned Cambodian politician Ly Yong Phat, citing his role in sheltering Chinese scammers within Cambodia. Law enforcement agencies believe the same Chinese crime networks are behind this entire "click a button" Ponzi epidemic, regardless of the specific country hosting the servers.
In a similar case, a U.S. judge ordered Eddy Alexandre and his company EminiFX to pay $228.5 million in restitution. This followed a crypto Ponzi scheme that defrauded over 25,000 investors with promises of 5-9.99% "AI returns."
