The Block reported that the U.S. Federal Court of Appeals heard the appeal of Roman Sterlingov, founder of the cryptocurrency mixing service Bitcoin Fog. The key issue is whether U.S. money transmission laws and Washington D.C. jurisdiction can apply to internet-based cryptocurrency services operating overseas. The defense argued that the FBI's undercover operation artificially created jurisdiction, while the prosecution countered that U.S. law applies because the service was provided to U.S. users. The court also focused on reviewing the reliability of the FBI's ‘IP overlap analysis’ evidence.
