Federal and civil enforcement actions this week underscore the persistent fraud risks in cryptocurrency fundraising, with two separate cases—one brought by the Justice Department and one by the SEC—alleging a combined $42 million in investor losses. The cases share a common thread: promoters allegedly diverted the vast majority of investor funds away from their stated purposes.
Benjamin Paul Wiener’s alleged $20 million Ponzi-like scheme
A federal grand jury indicted Sioux Falls crypto investor Benjamin Paul Wiener on 29 counts including wire fraud, money laundering, bank fraud, and aggravated identity theft. Prosecutors claim Wiener used eight interconnected entities—Benaiah Capital LLC, Benaiah Holdings, Inc., Benaiah Digital Fixed Income LP, Benaiah Digital LP, Benaiah Management Company, Inc., Benaiah Enterprises, LLC, Aslan Management, LLC, and Runway Four10—to lure investors across South Dakota and Minnesota. Wiener allegedly made materially false statements and moved funds through financial institutions and cryptocurrency exchanges to obscure their origin and control.
According to the indictment, when victim funds ran low or investors sought returns, Wiener solicited new investments to pay earlier backers and cover personal expenses. The government estimates total losses at about $20 million. In a separate facet, Wiener is accused of falsifying documents to obtain a $1 million line of credit from a Sioux Falls bank, using another individual’s personal identifying information without authorization. Wiener pleaded not guilty and was released on bond; trial is set for September 15.
SEC sues Mining Automatic and founder over $22 million raise
In a parallel civil action, the U.S. Securities and Exchange Commission charged Mining Automatic and its founder with raising approximately $22 million from investors while directing only about 13% of that sum toward actual mining operations. The complaint highlights a sharp disconnect between the mining-focused pitch and the alleged use of proceeds, though it does not specify what happened to the remaining 87%. The SEC frames the case as a crypto-mining fundraising scheme and seeks to enforce transparency and accountability in digital-asset offerings.
Both actions reflect growing regulatory scrutiny of how crypto ventures market themselves and manage investor capital. The Wiener case proceeds as a criminal matter with potential prison time, while Mining Automatic faces civil penalties. No specific tokens or blockchain networks are directly implicated in either matter, but the cases reinforce the message that fraud and misuse of funds remain active risks in the industry.
