SEC Scores Key Win Over Relief Defendant in Wintercap Crypto Case
The First Circuit has upheld the SEC’s authority to pursue relief defendants in a sprawling Wintercap crypto fraud case, clearing a path for the agency to freeze and recover millions tied to an alleged unregistered securities offering. The ruling strengthens the SEC’s enforcement muscle against anyone holding investor funds—even if they claim no knowledge of the fraud—while tightening the screws on offshore crypto platforms operating in U.S. markets. It matters because it signals a tougher stance on asset recovery and signals to crypto participants that simply receiving investor money may expose them to clawbacks.
The lawsuit traces back to 2018, when the SEC sued Roger Knox and his Wintercap entities for running an alleged Ponzi-like scheme that promoted WB21, a purported “world bank” cryptocurrency, as an investment contract. The agency claimed the tokens were unregistered securities and that Knox and the Wintercap companies raised tens of millions from U.S. investors through false claims. Raimund Gastauer, father of convicted fraudster Michael Gastauer, entered the case as a relief defendant after the SEC discovered he received roughly $10 million from the scheme. He argued he was a “mere conduit” who had already returned the funds to the Wintercap companies and should not be forced to repay them again.
The First Circuit rejected his arguments. The judges held that the SEC may name relief defendants in securities cases and may require them to return investor funds even without proving wrongdoing on their part. They also ruled that returning the funds to the fraudsters themselves does not satisfy the requirement to disgorge them to harmed investors. The court affirmed the lower court’s preliminary injunction freezing Gastauer’s assets and allowing the SEC to pursue recovery. The decision marks the first time the First Circuit has squarely addressed relief-defendant authority in a crypto-related SEC action.
This ruling clarifies that the SEC can legally reach into the wallets of anyone who briefly held investor money, regardless of fault. It broadens the agency’s reach beyond primary violators and violator-like entities to include family members, offshore entities, and third-party recipients. The decision does not require the SEC to prove Gastauer knew anything about the fraud, only that the funds originated from the unregistered securities offering.
For crypto markets, the First Circuit’s decision widens the SEC’s net for asset recovery. This erodes the hope many traders and developers hope to build around decentralization arguments—any person or smart contract that receives funds from an alleged securities violation can become a target. Stablecoin issuers and DeFi protocols that flow funds through multiple wallets may now face higher liability risk, especially if they receive funds from alleged unregistered offerings. The ruling will likely chill activity on offshore crypto exchanges and platforms that have been receiving U.S. investor money, and traders may become more cautious about accepting funds from suspected fraud-related schemes.
The decision signals to the SEC that courts will continue support its asset recovery efforts, so expect broader sweeps against third-party fund holders in upcoming crypto cases.
