Virtual Currency Networks. Brattle experts are currently assisting the U.S. DOJ and several investigative agencies of the federal government with a highly-complex criminal case in which the defendants are charged with operating a digital currency service that knowingly laundered money for criminal enterprises. We have organized and examined a large volume of seized evidence, identified key facts and information for the investigative and trial teams, and helped prepare material for exhibits. We have also identified testifying experts on related case-specific issues requiring testimony at trial.
