A federal grand jury has indicted South Dakota resident Benjamin Paul Wiener on 29 counts, accusing him of orchestrating a $20 million investment fraud scheme involving cryptocurrency and digital assets, the US Department of Justice (DOJ) announced Thursday.
Charges and Allegations
According to the DOJ, Wiener, 43, convinced individuals to invest substantial sums of money and digital assets in companies he controlled by issuing false statements and presenting misleading information about potential returns and the safety of their investments.
The indictment asserts that Wiener used funds from new investors to repay earlier participants after depleting previously available funds. Prosecutors claim he also financed personal expenses with money from investors, rather than directing it toward promised ventures.
Wiener’s indictment details allegations that he relied heavily on new investor contributions to fulfill obligations to existing investors and sustain personal expenditures after exhausting original funding sources.
The operation reportedly affected dozens of victims in South Dakota, Minnesota, and neighboring regions, resulting in significant financial losses to individuals who entrusted their money and digital assets to Wiener’s enterprises.
Legal Consequences
The indictment charges Wiener with wire fraud, bank fraud, money laundering, and aggravated identity theft. For the bank fraud charge, he could face up to 30 years in prison and a $1 million fine. Each wire fraud and money laundering count carries a penalty of up to 20 years in prison and a $250,000 fine. In addition, the aggravated identity theft count brings a mandatory two-year prison term, which would be served consecutively to any other sentence imposed.
Wiener’s legal proceedings will progress through the federal court system. The DOJ did not disclose further details regarding court dates or potential restitution for victims at this stage.
The Department of Justice, based in Washington DC, is the primary law enforcement agency in the United States responsible for investigating and prosecuting federal crimes, including fraud and money laundering involving digital assets.

Victims Spanned Multiple States

If convicted on all counts, Wiener could face decades in prison and major financial penalties.
