The U.S. Federal Appeals Court held oral arguments in the appeal case of Roman Sterlingov, the alleged operator of the crypto mixing platform Bitcoin Fog. The focus was on whether the U.S. Department of Justice has sufficient grounds to claim that Bitcoin Fog operated in Washington, D.C., and whether U.S. money transmission laws apply to internet-based crypto services catering to global users. During the hearing, judges also questioned the FBI's use of overlapping IP analysis to link accounts, citing a lack of clear statistical and peer-reviewed basis. This case is seen as one of the key examples of the U.S. prosecuting developers and operators of crypto privacy tools under the unregistered money transmission law, Section 1960. Related controversies also involve the Roman Storm and Samourai Wallet cases. (The Block) https://(wublock123.com)/news/bitcoin-fog-appeal-us-funds-transfer-law-global-crypto-scope-60983
