The United States Department of Justice charged the operator of crypto exchange AurumXchange with money laundering, alleging it processed millions for the darknet marketplace, Silk Road.

In an Oct. 28 statement, the DOJ alleges when 53-year-old Maximiliano Pilipis operated AurumXchange, over $30 million in funds across 100,000 transactions went through the exchange, some of which came from accounts held on the Silk Road.
