A U.S. federal grand jury has indicted South Dakota crypto investor Benjamin Paul Wiener on 29 charges, including wire fraud, money laundering, and bank fraud. Wiener is accused of orchestrating a Ponzi scheme that defrauded investors of approximately $20 million through eight entities, repaying early investors with funds from new investors. Prosecutors also allege that Wiener forged documents and impersonated others to secure a $1 million credit line from a financial institution in April 2025. He has pleaded not guilty to all charges and was granted bail. The trial is tentatively set for September 15.
