“U.S. Attorney General Eric Holder told a congressional panel Tuesday that bitcoin and other virtual currencies raise new risks for money laundering and other illegal activity. ‘More than ever before, the department’s law-enforcement work today must contend with new and emerging technology, including virtual currencies such as bitcoin,’ the attorney general said at a hearing before the House Judiciary Committee. ‘Virtual currencies can pose challenges for law enforcement given the appeal they have among those seeking to conceal illegal activity.’ In his remarks to Congress, Mr. Holder said federal prosecutors are working with financial regulators to understand the changing technology of money.”
