Is it known what happened to the Chipmixer owner? As far as I remember, he was also arrested, but is there any update on his case?
He might also seek some form of pardon or a reduced sentence, possibly by referencing the Tornado Cash case as precedent.
Are we sure they caught the real owner or just someone who was in charge of part of the whole operation? I can't remember that this person was convicted at all, because after the domain was seized, everything went into oblivion relatively quickly. Of course, this decision must have been very disappointing for those who portrayed all the participants in the sig campaign and the manager as some kind of criminals. As far as I know, no one ended up in prison or anything like that.
