The U.S. Securities and Exchange Commission has sued Nathan Fuller, a Texas resident, alleging he raised approximately $12.3 million from roughly 150 investors through a cryptocurrency investment scheme built on false claims of AI-powered trading bots, guaranteed returns, and insurance protections.

Market Context

The case represents one of the more significant enforcement actions involving alleged AI-driven crypto fraud in recent years. Regulators have increasingly targeted schemes that exploit investor enthusiasm around artificial intelligence and automated trading systems, particularly those promising unrealistic returns with minimal risk disclosures.

Analysis

According to the SEC complaint filed in the U.S. District Court for the Southern District of Texas, Fuller operated through Privvy Investments LLC and the assumed business names "Privvy Investments" and "Gateway Digital Investments." The agency alleges he sold passive joint-venture interests in a purported crypto arbitrage trading operation from at least October 2022 through mid-2024.

The SEC claims Fuller told investors that proprietary AI-based trading bots could scan cryptocurrency markets, execute high-frequency arbitrage trades, and limit losses through stop-loss coding. Those representations were allegedly false—the complaint states only about $380,000, or roughly 3% of investor funds, was used to purchase cryptocurrency without any bot involvement, with those trades generating no profits.

Fuller allegedly misappropriated at least $6.2 million for personal expenses including the purchase of a home, gambling, travel and vehicles. He also used approximately $5.5 million to make "Ponzi-like payments" to earlier investors, according to the SEC.

As withdrawal concerns grew among investors seeking to exit their positions, Fuller allegedly created fabricated account statements showing phantom gains, referenced fictitious entities, and even deployed artificial intelligence tools to generate a fraudulent letter from an purported auditing firm claiming investor accounts were under review pending liquidation into a trust.

The SEC charged Fuller with violating the registration and antifraud provisions of federal securities laws. The agency is seeking permanent injunctions, disgorgement, civil penalties, and a ban on participating in future securities offerings.

Key Numbers

- $12.3 million allegedly raised from approximately 150 investors

- ~$380,000 (roughly 3% of investor funds) actually used for cryptocurrency trading

- $6.2 million diverted for personal expenses including home purchase, gambling, travel, and vehicles

- $5.5 million used for Ponzi-like payments to earlier investors

- Returns promised at 40%-50% within 30-45 days; some exceeding 100% in under a month

- Separate bankruptcy proceeding denied discharge of more than $12.5 million in debt

What to Watch

The case proceeds through the Southern District of Texas federal court, where Fuller will face SEC enforcement action seeking disgorgement and penalties. A prior bankruptcy proceeding already resulted in denial of debt discharge after Fuller admitted operating Privvy as a Ponzi scheme and fabricating documentation, per DOJ records cited in court filings. Investors who participated in the scheme may be eligible for restitution claims as part of any eventual settlement or judgment.
