Samourai Wallet Co-Founder Gets 4 Years in Prison for $237 Million Bitcoin Laundering Scheme

21-Nov-2025 Crypto News Australia
  • Samourai Wallet co-founder William Hill was sentenced to four years in prison for operating an unlicensed money transmitting business after pleading guilty in July.
  • Prosecutors estimated Samourai Wallet processed at least $237 million in illicit proceeds, arguing the app was designed to launder and hide criminal money.
  • Hill’s sentence was lower than his co-founder’s, citing his age and autism diagnosis. Overall, the case aligns with a broader US crackdown on crypto mixing tools like Tornado Cash.

US authorities have handed down another prison term tied to crypto mixing tools, sentencing Samourai Wallet co-founder William “Bill” Hill to four years for running an unlicensed money transmitting business.

Hill, 67, pleaded guilty in July in the Southern District of New York. “I pled guilty because I am guilty. I am deeply remorseful and ashamed of what I did”, Hill said.

Prosecutors estimate Samourai processed at least US$237 million (AU$355.5 million) in illicit proceeds and argued in an August filing that the app was “designed and operated as a service for transmitting criminal proceeds”.

Prosecutors added that Hill and co-founder Keonne Rodriguez knew it was being used to launder and hide money. 

The over $237 million dollars of criminal proceeds laundered through Samourai came from, among other things, drug trafficking, darknet marketplaces, cyber-intrusions, frauds, sanctioned jurisdictions, murder-for-hire schemes, and a child pornography website.

Rodriguez previously received a five-year sentence, the maximum allowed.

Hill To Do Time In Lisbon

Judge Denise Cote cut Hill’s term below that ceiling, citing his age and recent autism diagnosis as factors that would make imprisonment unusually hard. 

Hill will also serve three years of supervised release, which he can complete from Lisbon, and pay a US$250,000 (AU$375,000) fine. The judge said she would recommend credit for time he spent in custody in Portugal before extradition.

The case fits a broader crackdown on crypto privacy tools. Similarly, Tornado Cash developer Roman Storm was convicted in August on a similar unlicensed money transmission charge, though jurors did not convict on money laundering and sanctions counts.

Another Tornado Cash developer, Alexey Pertsev, was sentenced to 64 months in prison for money laundering by Dutch judges.
