This chapter examines the Virtual Currencies and Terrorist Financing. The rise of forms of payment that are independent of governmental issued and controlled currencies, and which can be traded in a highly anonymous, instantly transferred and used for both legal and illegal transactions represent a new means of laundering money destined to finance the operations of terrorist organizations. Because virtual currencies have the capability of being used (legally) with lower fees than traditional funds transfer modalities, it is likely that their use will increase, and that legitimate organizations will make use of them. Understanding this new form of government-independent “money” is important to those involved in the field of terrorist interdiction.
