Federal sentencing and new data point to rising digital asset fraud risks as illegal activity grows with wider adoption.
Federal authorities in Utah have sentenced a man to prison for a fraud scheme involving cryptocurrency and illegal cash transfers. Prosecutors said the case involved millions of dollars in losses and exposed ongoing risks tied to crypto-related crime in the United States. Authorities described the conduct as deliberate and harmful to both individual investors and the financial system.
Investors Lose Millions as Crypto Scheme Operator Sentenced
Brian Garry Sewell, 54, received a 36-month prison sentence, followed by 3 years of supervised release, after pleading guilty to wire fraud. Investigators said the fraud resulted in losses of more than $2.9 million to investors. Court records show that at least 17 victims were affected over several years.
According to the U.S. Attorney’s Office for the District of Utah, Sewell carried out the scheme between December 2017 and April 2024. He solicited money and cryptocurrency by claiming he had the skills and background needed to deliver high investment returns. Prosecutors said those claims were false, and investor funds were misused rather than invested as promised.
Separately, Sewell also pleaded guilty to operating an unlicensed money-transmitting business. From March to September 2020, he ran Rockwell Capital Management, converting more than $5.4 million in bulk cash into crypto for third-party clients. Authorities said some of those clients were linked to investment fraud schemes and drug trafficking.
Moreover, federal officials stated that Sewell charged transaction fees. All while ignoring required registration and reporting rules under U.S. anti-money laundering laws. Both criminal cases were sentenced at the same time, with prison terms running concurrently, resulting in a total sentence of three years.
U.S. District Court Judge Ann Marie McIff Allen ordered Sewell to pay more than $3.6 million in restitution related to the wire fraud charge. Additional restitution was also ordered to the U.S. Department of Homeland Security.
FBI Special Agent in Charge Robert Bohls said Sewell misled victims by promising returns he could not produce, leaving families to absorb serious financial losses. Prosecutors emphasized that false claims of expertise played a key role in gaining investor trust.
Digital Asset Adoption Brings a Sharp Rise in Illegal Activities
Crypto-related crime continued to climb in 2025, raising concerns for regulators and law enforcement agencies worldwide. New data points to a sharp rise in illegal transactions tied to digital assets. Wider adoption of cryptocurrencies has brought fresh challenges around tracking and enforcement.
Recent figures from Chainalysis show illicit crypto addresses received about $154 billion in 2025. This is a 162% jump from the revised $57.2 billion recorded in 2024. Much of the increase came from a small group of state-linked actors.
It includes networks connected to North Korea, Russia, Iran-aligned groups, and Chinese money laundering operations. North Korean-linked hackers were responsible for roughly $2 billion in stolen crypto during the year.
According to Chainalysis, 2025 marked their most damaging period to date, both in scale and complexity. Most of those losses stemmed from a February exploit targeting Bybit, where nearly $1.5 billion was stolen, making it the largest digital heist in crypto history.
