Key Takeaways:
A U.S. federal appeals court on Tuesday heard arguments in the case of alleged Bitcoin Fog operator Roman Sterlingov, testing the Justice Department's theory that U.S. law applies to any crypto service with American users, regardless of where it is based. The hearing focused on whether prosecutors had sufficient evidence to establish venue in Washington, D.C., for a service allegedly run abroad.
"If this is the standard for venue in internet cases, then any government agent can just unilaterally send a message to any website anywhere in the world," defense attorney Tor Ekeland argued before the three-judge panel of the U.S. Court of Appeals for the D.C. Circuit.
Prosecuting attorney Jenny Ellickson countered that Bitcoin Fog knowingly operated an international money transmission business serving U.S. users and was therefore subject to U.S. laws. A significant portion of the hearing was dedicated to the reliability of testimony from an FBI investigator who linked accounts using "IP overlap" analysis. One judge repeatedly questioned the statistical basis for the investigator's conclusion, highlighting the defense's argument that the method lacks established "error rates" or "scientific peer-review."
The decision, now submitted to the panel, could set a major precedent for the crypto industry. A ruling favoring the DOJ would expand U.S. legal reach over foreign privacy tools and decentralized exchanges with any U.S. transaction connection. This could directly influence how developers of services like Tornado Cash and Samourai Wallet are prosecuted under federal money transmission laws.
At the heart of the legal battle is Section 1960, the federal unlicensed money transmission law used to convict Sterlingov in 2024 on charges of moving hundreds of millions of dollars tied to darkweb markets. This same statute is being used against Tornado Cash developer Roman Storm and the co-founders of Samourai Wallet.
The defense's core argument is that the government artificially "manufactured" its case in Washington, D.C., by having undercover agents use the service from within the district. The appeal challenges the fundamental premise of whether interacting with U.S. users online automatically places a foreign-operated service under the purview of American courts and regulations.
The case highlights a growing tension between borderless crypto networks and nation-state laws. A ruling that upholds the conviction could embolden U.S. prosecutors to pursue a wider range of developers and services that facilitate crypto privacy, forcing a stricter compliance and geofencing environment globally. Conversely, a reversal could limit the DOJ's enforcement capabilities against international crypto platforms, creating a more complex legal landscape for privacy-enhancing technologies. The crypto policy group Coin Center has recently backed revised legislative language that would require "specific intent and knowledge" to secure convictions under Section 1960, a move aimed at protecting developers from overly broad prosecutions.
