Summary
- Japheth Dillman was found guilty of wire fraud and conspiracy linked to the downfall of Block Bits Capital.
- He misled investors by claiming that the fund's automated trading software was operational when he was aware it was not.
- Instead of investing in the promised software, he and an accomplice used investor funds for personal gain and risky ventures that resulted in significant losses.
A federal jury in San Francisco has convicted Japheth Dillman, the founder of Block Bits Capital, for wire fraud and conspiracy. Prosecutors demonstrated that he deceived investors by promoting trading software that he knew was nonfunctional, as reported by the Justice Department on Monday.
Between June 2017 and August 2018, Dillman, 48, attracted nearly $1 million from over 20 investors by claiming that the fund would profit from automated cryptocurrency trading utilizing a proprietary tool named the Autotrader, which he asserted was fully operational.

In reality, the algorithm was nonfunctional, and prosecutors indicated that Dillman was aware of this, meaning the funds could not be utilized as he had promised. Instead, he and an unnamed co-conspirator diverted the money to pay themselves and make speculative investments in other crypto projects, while falsely assuring investors that their contributions were being safeguarded.
These risky investments incurred heavy losses, and Dillman subsequently misled investors into believing that Block Bits was generating substantial profits, when the reality was a continuation of losses.
Sentencing Scheduled for December
Dillman was convicted after a 10-day trial presided over by U.S. District Judge Richard Seeborg and is currently out on bond. He is set to be sentenced on December 8, potentially facing up to 20 years in prison and a $250,000 fine for each charge, with the judge determining the final sentence based on federal guidelines.
The investigation was conducted by the FBI and IRS Criminal Investigation, with assistance from the SEC's San Francisco office. The prosecution was led by Assistant U.S. Attorneys Christiaan Highsmith and Charles Bisesto.
In the previous year, cryptocurrency-related scams constituted more than half of the total reported losses from scams and cybercrime in the U.S., according to the FBI's complaint center. Investment frauds alone accounted for $8.6 billion, marking a 32% increase from 2024.
This figure only reflects what victims report to authorities, and the Consumer Federation of America has suggested that the actual losses are significantly higher, as most victims do not file complaints.
