[Bitcoin Fog Appeal Case Focuses on Jurisdiction Dispute, U.S. Department of Justice Advocates Global Applicability] Odaily Planet Daily News: The U.S. Federal Court of Appeals is hearing the appeal case of Roman Sterlingov, centering on whether cryptocurrency services fall under U.S. legal jurisdiction. Key discussions in the case include: whether a small number of transactions conducted by law enforcement in Washington are sufficient to establish jurisdiction; and the reliability of evidence from the FBI's 'IP overlap analysis' used to identify the defendant. The U.S. Department of Justice argues that Bitcoin Fog, as a global money transmission service targeting U.S. users, should be subject to U.S. law, while the defense questions whether law enforcement has 'artificially created jurisdiction.'
