The Securities and Exchange Commission (SEC) filed a lawsuit against Nathan Fuller and his firm Privvy Investments LLC on Friday, alleging the Texas resident orchestrated a $12.3 million cryptocurrency fraud. Filed in the U.S. District Court for the Southern District of Texas, the complaint claims Nathan Fuller lured approximately 150 investors with promises of high-frequency arbitrage trading powered by sophisticated AI “bots” that federal regulators say never actually existed.
The scheme, which reportedly operated from October 2022 through mid-2024, utilized the business names Privvy Investments, LLC and Gateway Digital Investments. According to the SEC, Nathan Fuller told prospective clients his proprietary technology could automatically exploit price discrepancies across various cryptocurrency exchanges. He marketed these non-existent tools as a low-risk gateway to massive returns, sometimes promising profits of up to 100% in as few as 21 days.
Investigators allege the entire operation functioned as a classic Ponzi scheme rather than a legitimate trading platform. While Nathan Fuller claimed the funds were protected by FDIC insurance and professional liability coverage, the SEC asserts that only 3% of the $12.3 million raised was ever used for actual cryptocurrency trading. The majority of the capital was allegedly used to pay back earlier investors or fund Nathan Fuller’s lavish lifestyle in Cypress, Texas.
SEC allegations Detail the scale of the Privvy crypto fraud
The SEC complaint paints a picture of a calculated deception spanning nine U.S. states and two foreign countries. Nathan Fuller allegedly convinced investors that his “bots” were scanning the global markets for momentary price gaps. To build a veneer of institutional security, he claimed the investments were backed by surety bonds, a move likely intended to lower the guard of those wary of the volatile digital asset space.
Financial records cited by the SEC suggest that of the $12.3 million collected, Nathan Fuller misappropriated at least $6.2 million for personal expenses. These purchases reportedly included a $1 million home, a Jeep, high-end trading cards, and significant spending on travel and gambling. This news comes as many investors are increasingly wary of fraudulent recovery schemes and similar digital asset traps that often follow high-profile market movements.
The remaining $5.5 million was used to make “Ponzi-style” payments to existing investors. By using new capital to fulfill withdrawal requests, Nathan Fuller was able to maintain the illusion of a profitable enterprise for nearly two years. This tactic allowed the scheme to grow significantly before regulatory scrutiny finally brought the operation to a halt in the Southern District of Texas.
The role of AI hype in modern investment scams
The Privvy case highlights a growing trend where bad actors use the buzz surrounding artificial intelligence to dress up traditional financial crimes. By claiming his bots used AI to execute high-frequency arbitrage, Nathan Fuller capitalized on the general public’s fear of missing out on the next technological breakthrough. Federal regulators have increasingly warned that “AI” has become a buzzword used to mask a lack of underlying substance.
This exploitation of emerging tech is not isolated to small-scale individual fraud. The broader market remains sensitive to how new technologies interact with established assets, as seen in how AI-driven DEX activity can influence investor sentiment across major networks like Ethereum. In the case of Privvy, the AI was a total fabrication designed to explain away the “outsized” returns Nathan Fuller promised his victims.
The SEC’s legal action seeks permanent injunctions, the return of “ill-gotten gains” with interest, and civil penalties against Nathan Fuller. The agency continues to emphasize that no matter how complex the technology sounds, the basic rules of securities law still apply. If an investment sounds too good to be true—such as 40% returns in 30 days—it almost always is.
Ongoing regulatory pressure on the digital asset sector
This lawsuit arrives amid a period of intense pressure on the crypto industry from U.S. federal agencies. While some lawmakers are working on the CLARITY Act to provide better frameworks for digital assets, the SEC remains focused on enforcement actions against what it deems “unregulated and fraudulent” entities. The Privvy case serves as a stark reminder of the risks present in the “shadow” crypto market.
For the 150 investors who trusted Nathan Fuller, the path to recovery is uncertain. While the SEC pursues the misappropriated $12.3 million, much of the capital has already been spent on depreciating assets or lost through gambling. The case is expected to proceed in the Texas court system, where federal prosecutors may also take an interest in the criminal elements of the alleged Ponzi scheme.
As the legal process unfolds, the industry is left to reflect on the dangers of “black box” trading algorithms. Without transparency or third-party audits, investors remain vulnerable to founders who claim to have a technological edge that does not actually exist. The SEC’s message is clear: the era of hiding fraud behind the curtain of AI and blockchain is rapidly closing.
