Ripple Labs, which distributes and exchanges its own cryptocurrency, XRP, is being fined $700,000 by FinCEN, a division of the Treasury Department, for “acting as a money services business (MSB), and selling its virtual currency… without registering with FinCEN,” as well as for “failing to implement and maintain an adequate anti-money laundering (AML) program designed to protect its products from use by money launderers or terrorist financiers,” according to FinCEN
