Appeals Court Upholds Conviction of Mixer Operator

The US Court of Appeals for the Second Circuit on Tuesday unanimously affirmed the conviction of the operator of a popular cryptocurrency mixing service, rejecting the defence's arguments that the prosecution violated First Amendment protections and that the underlying money-transmission statute is unconstitutionally vague as applied to non-custodial software.\n\nThe panel's 47-page opinion is expected to be cited in several pending mixer-related prosecutions and may influence the policy debate over privacy-preserving tools in the digital asset sector.
