A federal jury in California has convicted Japheth Dillman, 48, from San Francisco, of wire fraud and conspiracy to commit wire fraud, following a scheme that defrauded over 20 investors out of nearly $1 million. The U.S. Department of Justice announced the conviction on August 24, 2026, confirming that Dillman, the founder and managing director of Block Bits Capital LLC, misled investors with promises of a sophisticated, non-existent cryptocurrency trading bot.
The verdict comes after a 10-day trial presided over by U.S. District Judge Richard Seeborg in the Northern District of California, San Francisco. This case highlights ongoing concerns about deception in the cryptocurrency investment space, where promises of high-tech trading solutions can often mask fraudulent operations.
What was the scheme behind Block Bits Capital?
Japheth Dillman, a co-founder and general partner in a Block Bits fund, along with co-conspirator David Mata, raised approximately $960,000 from about 22 investors between June 2017 and August 2018. They did so by falsely claiming Block Bits Capital used "advanced algorithmic trading" through an "Autotrader" software that was supposedly "finished and working." According to court documents and evidence presented by Assistant U.S. Attorneys Christiaan Highsmith and Charles Bisesto, Dillman knew this automated algorithm was not functional and investor funds could not be used as promised.
Instead of deploying the promised trading strategy, Dillman and Mata used investor money to pay themselves and make risky, speculative investments in other cryptocurrency ventures. These ventures, as detailed in trial evidence, "resulted in huge losses." To compound the fraud, Dillman "falsely told investors that Block Bits cryptocurrency trading had led to significant profits when in fact the trading led to more losses of investor funds."
What was the financial impact on investors?
More than 20 investors were defrauded, with the fraudulent scheme involving "nearly $1 million." The SEC had earlier alleged that investor losses, after failed trades, exceeded $500,000. These figures underscore the substantial financial damage inflicted by Dillman's deceptive practices.
David Mata, identified as a co-conspirator in the scheme, had already settled with the SEC in a parallel civil complaint filed in April 2022. Mata agreed to disgorge $86,624, which included $75,000 plus prejudgment interest of $11,624. The criminal complaint against Dillman, alleging wire fraud, was filed on April 26, 2022.
What are the penalties Dillman faces?
For each count of conviction—wire fraud and conspiracy to commit wire fraud—Japheth Dillman faces a maximum statutory penalty of 20 years in federal prison and a $250,000 fine. U.S. District Judge Richard Seeborg will oversee Dillman's sentencing hearing, which is scheduled for December 8, 2026, at 9:30 a.m. The severe potential penalties reflect the gravity of financial fraud and the deliberate deception of investors.
This conviction serves as a stark reminder of the risks associated with unchecked claims in the fast-evolving world of cryptocurrency investments. Dillman's background, including co-founding YetiZen, an accelerator for game industry startups, highlights that even individuals with prior entrepreneurial experience can engage in sophisticated financial deception.
