Federal prosecutors in the United States have charged South Dakota cryptocurrency investor Benjamin Paul Wiener in connection with an alleged investment fraud scheme that authorities estimate caused approximately $20 million in losses to dozens of investors.
According to the U.S. Department of Justice, a federal grand jury returned a 29-count indictment that includes charges of wire fraud, money laundering, bank fraud, and aggravated identity theft. Wiener has pleaded not guilty, and the case is expected to proceed to trial in September.
Alleged Multi-Company Investment Scheme
Investigators claim Wiener used a network of eight business entities to attract investors by making false representations about investment opportunities involving digital assets.
Prosecutors allege that investor funds were collected through these companies and later transferred through various financial institutions and cryptocurrency exchanges, making it more difficult to trace the origin and movement of the money.
Authorities believe the transactions were structured to disguise ownership and conceal the flow of funds.
New Investor Funds Allegedly Used to Repay Earlier Investors
According to court documents, prosecutors claim that when available investor funds became depleted—or when existing investors requested withdrawals—new investments were allegedly used to repay earlier participants while also covering personal expenses.
Investigators argue this pattern allowed the operation to continue despite a shortage of available capital.
Additional Bank Fraud Allegations
The indictment also includes separate allegations related to a $1 million line of credit reportedly obtained from a financial institution in South Dakota.
Prosecutors claim fraudulent documentation and unauthorized personal identification information were used during the credit application process. Authorities have not publicly identified either the financial institution or the individual whose identity was allegedly involved.
Legal Process Continues
Wiener remains presumed innocent under U.S. law unless proven guilty in court. The upcoming trial is expected to examine the evidence surrounding the alleged investment operation, financial transactions, and related fraud charges.
The case highlights the growing attention regulators and law enforcement agencies are giving to cryptocurrency investment schemes as digital asset markets continue to expand.
