Introduction Due to the rapid developments in spheres of financial innovation and information technologies, world space is being transformed into a global business system (Akopova and Przhedetskaya, 2016; Boldeanu and Tache, 2015; Dmitrishina and Uskov, 2015; Epifanova et al., 2015; Fatai, 2015; Rusanov et al., 2015; Rupeika-Apoga and Nedovis 2015; Thalassinos et al., 2013; Thalassinos and Stamatopoulos, 2015; Thalassinos, 2007). The volume of electronic payments in recent years has grown significantly with the introduction of computers and information technology into virtually all spheres of daily activity. The volume of e-commerce in Russia in 2013 reached $ 13 bin, an increase of 35% as compared to 2012. At the end of 2013 about 7.2 million people in Russia have used e-wallets for payments and mutual settlements. The market volume of electronic purses is estimated at $9 billion in 2015, with an outlook to its exponential growth. Dynamic changes in the world processes, particularly in the virtual economy sphere pose challenges to the national security system. Rationale According to the Decree of the President of the Russian Federation as of 31.12.2015, No 683 "On the Russian Federation National Security Strategy" national security--is a state of security for the individual, society and state from internal and external threats, which provides a realization of the constitutional rights and freedoms, decent quality of life, sovereignty, independence, statehood and territorial integrity, as well as sustainable economic and social development of the Russian Federation. National security also includes information security. The National Security Strategy it is stated that amongst the main strategic risks for the economic sphere of Russian Federation in long term are: high dependence on the external economic environment, the lag in the development and implementation of advanced technologies, the vulnerability of the national financial system from actions of non-residents, as well as speculative foreign capital. In this regard, the system is required to provide protection mechanisms, including the regulatory, legal and organizational support of the development of economic processes that meet modern international realities and minimize the risks of illegal activities. Main issue is the balance between the state measures, which can potentially harm the virtual economy, and legislation enabling participants to carry out operations with virtual currency for criminal purposes. The economic system is dynamic, committed to the development and includes the use of new technological opportunities. This aspect has led to the need for continuous improvements in the national security measures. In particular, the emergence of virtual currencies (cryptocurrency) is actively discussed globally, the most famous of these is the Bitcoin. The Bitcoin is widely spread in many countries, competing with the national currencies, such the euro and the dollar. This Bitcoin is not secured by any assets, and is not tied to any world currency--its rate is determined by supply and demand, making Bitcoin exchange rate volatile, yet objective at the same time. All Bitcoin transactions records are kept in the public domain, but without information disclosure of the actual participants, turning this innovative payment instrument into one of the mediums facilitating criminal activity. Currently, every 10 minutes 25 new Bitcoins are added to the network. In other words, if the user runs a special program his/her computer solves a mathematical problem. Correct solution will earn some amount of Bitcoin to the user. The exchange rate of Bitcoin is unstable, last year it ranged from $100 to $1100, with recent months level about $600. According to official statistics, the total volume of issued Bitcoin is estimated at $8 billion. Legal status of cryptocurrency, despite the widespread dissemination and use of the Internet, is not legally secured and requires detailed consideration not only by lawyers and economists, but first and foremost by software engineers. …
