The purpose of the article is to explain the use of cryptocurrency as a terrorist financing tool. This article has emphasized the ways, which terrorists appraise for being a reliable fundraising means and their adoption. Methodology. For the purposes of the study, the methods of scientific abstraction, synthesis, observation, generalization, as well as the method of induction of literature and legal documents were used to determine the features of bitcoin, promoting and preventing its use for terrorism financing. Results. The development of the Internet and electronic devices has radically changed all spheres of human life, including criminal activity. Digitalization has led to the improvement of ordinary crimes and the emergence of new types of crime, which, in principle, cannot exist without special digital electronic devices. Among the first implementers of new technologies were terrorists, who took advantage of digitalization to increase profitability. Thus, terrorists have now significantly increased their attention to cryptocurrency as a digital means of payment, namely Bitcoin. Bitcoin has a number of features that have attracted the attention of criminals as a way to evade responsibility for a crime. In particular, decentralization avoids the need for confirmation by a central authority, and pseudo-anonymity provides a certain level of anonymity. In addition, terrorists are aware that Bitcoin's confidentiality is extremely fragile and needs to be enhanced. The paper analyzes several ways to enhance anonymity, such as software that anonymizes traffic and prevents IP identification, peer-to-peer mixers, centralized mixing services (tumbler), and other approaches. It is worth emphasizing that for the fight against crime, the main issue is the de-anonymization of the Bitcoin owner/user, which allows the identification of the criminal. Currently, law enforcement agencies use direct and indirect de-anonymization, proliferation analysis, quantitative analysis, time analysis, and transactional network analysis, among others, to achieve the above goal, which are discussed in detail in this article. In addition, agencies around the world investigated and uncovered terrorist groups and their financial facilitators. Specifically, on August 13, 2020, the U.S. Department of Justice's Office of Public Affairs announced "the largest cryptocurrency seizure in the context of terrorism in history." To investigate the agenda, the legal documents of those investigations that contain information about the terrorist fund-raising mechanism were examined and analyzed. The legal documents revealed that these investigations used the aforementioned de-anonymization approaches.

Annotation. The article is aimed at the study of cryptocurrency systems and methods of their classification by various properties and characteristics. Despite the active study of cryptocurrency systems by modern scholars, there is still no general consensus on the categorization of classifications. The result of this ambiguity is a general lack of practical understanding of the various forms of cryptocurrency at both the consumer and government levels around the world. The consequence of the article is the division of the whole set of cryptocurrencies to correct this ambiguity. The author has developed a generalized classification of cryptocurrencies, which is designed to fill certain gaps in the study of cryptocurrencies. The most important classification features are revealed and the table of classification of cryptocurrency systems is made, where cryptocurrencies are divided into types and subspecies. The purpose of the article is to develop a detailed classification of cryptocurrencies based on the systematization of existing knowledge about cryptocurrency systems. Nowadays, there are more than 2,000 cryptocurrency systems in the world. And the rapid development of these systems in recent years has forced many not only scientists but also ordinary people to study this area in more detail. Cryptocurrency is the evolution of financial technologies and cryptographic methods. The emergence of the first cryptocurrency - bitcoin led to the creation of new cryptocurrencies, which necessitated their systematization. Cryptocurrencies should be divided into groups according to their features and characteristics in the following categories: purpose, issue size, viability, originality, centralization, availability of innovations, method of rotation, legal status, type of creation, method of production, generation algorithm, encryption method, speed, scope application, degree of dependence, security, volume of capitalization, market value. The algorithms for generating cryptocurrency systems, in particular Proof-of-Work and Proof of share, are considered. The analysis shows the diversity and versatility of cryptocurrency systems. Key words: cryptocurrency, classification, virtual assets, bitcoin, mining, fork.

Annotation. Introduction. At the present stage of development of the world is the rapid functioning of all spheres of society. Based on this, today society seeks to be progressive, modern, and therefore the world introduces us to a new type of money that is gaining popularity – cryptocurrency. Currently, humanity is aimed at finding a more progressive way of realization of any financial transactions with minimal risk. Now, the cryptocurrency is in the same city, where was the first paper money during the popularization of the concept of “printing money”. That is why, after a certain period of time cryptocurrency calculations become commonplace. Purpose. The purpose of the study is to consider cryptocurrency as the currency of the future financial system and possible prospects for its future development in Ukraine and the world. Results. The article discusses the theoretical aspects and history of cryptocurrency as currency future financial system. The main types of cryptocurrencies, the process of their creation, which is based on the solution of computers to complex mathematical problems and their entry into the market, are identified. The advantages and disadvantages of using cryptocurrencies are studied, as well as its feature as decentralization, which distinguishes it from other currencies. It is emphasized that in the world, so far, there is no consensus on the further strategy for the development of cryptocurrency in the world, its legalization and legality of use, thus analyzing the legal status of cryptocurrency in different countries and prospects for use. The legal regulation of cryptocurrencies in Ukraine in accordance with the norms of Ukrainian legislation is considered. The peculiarities of the functioning of virtual currencies in Ukraine are highlighted. Conclusions. Cryptocurrency inevitably and actively popularized worldwide in furthering decade. In some areas, such as online gaming business, this kind of currency has found its application in full. In Ukraine, there is everything necessary for legal operations with cryptocurrencies, but it is at the legislative level that there is a problem that prevents the active distribution and use of such currencies. The situation when cryptocurrency is not banned, but also not allowed, is an additional reason for fraudulent schemes. Legal entities and individuals who want or are able to use cryptocurrency is not protected. Similarly, the state can not get taxes from prospective activities. That is why the need for a clear establishment of the concept of “Cryptocurrency” by the law of Ukraine and the creation of mechanisms for regulating any activity with cryptocurrencies at the legislative level, are the priority state tasks at present. Keywords: cryptocurrency; currency; bitcoin; mining; digital currency; the legal status.

The emergence and popularity of the cryptocurrency has caused a great deal of controversy in the scientific community over market development opportunities, further use of virtual money, and its integration into traditional accounting systems. The global financial market creates many opportunities to use electronic and virtual money for various types of transactions, and the question of how to record cryptocurrency and related transactions in accounting remains relevant. The aim of the research is to evaluate the alternatives of cryptocurrency accounting. For the research methods of scientific literature analysis, comparison, interpretation, information systematization, generalization were used. Although various authors, national and international accounting standards regulators provide their insights and recommendations on cryptocurrency accounting, a unified system has not been formed yet. Currently are analysed such alternatives of cryptocurrency accounting as financial asset, intangible asset or inventory.

Introduction. In the coming years, the accounting sector is expected to undergo major changes due to the fact that Blockchain technology is being actively introduced in the financial sector of the countries. The article gives a critical assessment of the situation, as well as discusses the problematic aspects and prospects for the development of the blockchain in the system of accounting and auditing. The definition of the economic content of the blockchain is investigated. It has been found that the cryptocurrency system works on Blockchain technology, the essence of which is the possibility of a separate group of people to manage a virtual "ledger", i.e. one sheet of such a book is a block, and the book itself is a chain of block sheets. The platform is a public register based on distributed ledgers, which can be shared across multiple network nodes, providing each participant with their own copy. The studied technology has an important feature for accounting, because the information created in this database can be trusted, even if there is no trust in the counterparty. Blockchain technology is the basis of the basic principles of cryptocurrency: transparency, anonymity, decentralization,speed and security. Blockchain technology and one of the products of its implementation - cryptocurrency, can really be a starting point for the transformation of the world economy and its implementation in Ukraine. With the help of the blockchain, the relations «state-business», «business-business», «population-state» can change significantly. In other words, the main transformation will be related to the possibility of delegating to a computer program (algorithm) the conduct and certification of transactions without the participation of third parties (state, banks, other intermediaries), the results of which will be trusted by all or most economic entities (market). Methods. The authors used the following scientific methods in the process of research: induction and deduction - in the process of studying the general trends of Blockchain development in Ukraine, analysis and synthesis - during theoretical generalizations, formation of appropriate conclusions; bibliographic - research of literary sources to obtain the necessary information on the research topic; method of associations and analogies - for proposed new ideas and proposals that arise from comparison with other more or less similar objects. Results. Proponents of Blockchain technology believe that the new tool will be able to replace not only accountants but also banking institutions and many financial intermediaries. According to the Blockchain Research Institute, Ukraine was on the list of 14 countries that were recognized as leaders in the implementation of Blockchain. However, the state needs to restructure huge systems with a huge number of people to use this tool. Blockchain technology aims to put an end to traditional methods of accounting, documentation, processing, registration, inventory systems. Blockchain allows companies to register both parties to a transaction simultaneously in a shared book in real time, rather than storing matched records of financial transactions separately in a private database. The need for traditional double-entry bookkeeping will be eliminated, as the verification of the legality of accounting will be fully automated. Disscusion. The main task set when writing the article is to substantiate the feasibility of using blockchain technology in accounting and auditing.

The purpose of this research is to determine the prospects for the use of cryptocurrencies on the example of bitcoins. In the process of theoretical research economic and legal features of cryptocurrencies are revealed: their performing of the money functions, types of economic transactions carried out with their involvement, the legal security of the cryptocurrency market. Problems related to the decentralization of cryptocurrencies are analysed. Among them there are the threat to the stability of national currencies, the use of cryptocurrencies for financing of criminal activities, weak financial control over operations in cryptocurrencies, which reduces the possibility of adequate taxation of related incomes. It was found that improving the legal structure of cryptocurrency circulation, ensuring financial control over it would help to reduce the economic dangers and risks associated with the use of virtual money. The tendencies in change of the extracted volume, exchange price, market capitalization of such cryptocurrency as bitcoin are analysed. It is determined that bitcoin shows sharp price fluctuations over short periods of time that are not related to its quantity. But the demand and supply of bitcoins are influenced not only by speculative expectations, but also by fundamental factors, that influence the prices of other stock assets. In addition, the price of bitcoins is affected by development of the computer technologies and by legislative changes. This allows to make predictions about the dynamics of the price of virtual money. Scenarios for the development of the cryptocurrency market in Ukraine are proposed. Legislative support for the bitcoin market would accelerate its development, make its operations safer for its participants and help to counteract money laundering operations.

The purpose of the work is to determine the main approaches to the organization of accounting and management in a modern enterprise. The study found that blockchain technology supports the invulnerability and independence of the interests of legal entities in relation to the influence of third parties. The introduction of blockchain technology in accounting contributes to the innovative development of the system in the enterprise during the use of cryptocurrency in payments between buyers and customers. The article presents the main risks of using virtual currency. Implementation of modern technologies for the enterprise, such as cloud storage, XBRL technology, blockchain, violates the new requirements for the presentation of business (financial) reporting data and their transfer to stakeholders. Any technology must provide confidence in the representativeness of information and trust in it. The model of carrying out operation between the enterprises by means of cryptoactive assets is offered. The types of risks from the use of certain funds are analyzed. It is

Modern transformational changes occurring in the socio-economic life of countries are conditioned by the evolution of information and communication technologies, the deployment of globalization, decentralization, the strengthening of the openness policy and the increase of efficiency of use and hence the transition from a bureaucratic model of government to a consensus model, a built model. implementation of entrepreneurial management mechanisms in providing social services to the population actualize the need for rethinking and justification the structure of public finance in the new environment. On the basis of systematic analysis, the theoretical aspects of «public finances» are revealed in the article, their structure is substantiated and the necessity of application in scientific circulation as an important dominant of civil society is proved. It is emphasized that the essential characteristics of this definition are revealed by the existence of financial and economic relations between the population, the state, other public institutions and economic entities regarding the formation, distribution, and use of public funds to meet the public needs of the population. It is shown that the structure of public finances is formed by state and local finances, finances of communal enterprises and state corporations, finances of enterprises and organizations of communal ownership, extrabudgetary trust funds and public funds. Among the dominant features of public finances in the context of modern transformations are transparency and imperative character. It has been argued that the vector of public finance reform must continue to be decentralization, which, in addition to the redistribution of resources and powers, should promote the extension of the financial powers of local governments, increase the transparency of both public and local finances, and raise public accountability. the public sector and improving the quality of life of the population.

The use of cryptocurrencies is actively spreading in a lot of countries around the world on the basis of economic and technological progressive development. Cryptocurrency attracts investors to launch the initial coin offering (ISO). Cryptocurrency has important features: it is not controlled by the state, does not require the participation of a third party in the calculations. Cryptocurrency transactions are confidential. However, the lack of legal regulation and a unified approach to determining the economic essence of cryptocurrency makes it difficult to reflect in the accounting.

Problem setting. Comprehensive digitalization of all spheres of life, as one of the most important factors of economic growth in any country, is the mainstream of the modern global world. Digital transformations in the economy are changing approaches to both the organization and conduct of economic activity and the format of its state regulation. The development of the digital economy is inextricably linked with the “digitalization” of a number of traditional objects and / or forms of interaction between participants in economic relations, as well as the emergence and active circulation of new objects whose existence is possible only in digital format (“ digital objects “). Virtual assets / cryptocurrency are one of such objects to which there has been a bivalent attitude since its appearance, and to the legal nature of which a unified approach has not been formed to date. Analysis of recent researches and publications. Among the researchers who in their works addressed the issue of the legal nature of virtual assets / cryptocurrency and transactions with it, it should be noted M.V. Grebenyuk, B.V. Derevyanko, I.M. Doronin, A.T. Kovalchuk, L.O. Nikitin, S.S. Pylypyshyn, V.A. Ustymenko and others. At the same time, a full-scale study of this issue, in particular from the standpoint of economic law, requires further legal, including economic and legal research. Target of research is to study the heterogeneous nature of virtual assets / cryptocurrencies in the context of digital transformations in the economy and modernization of domestic legislation. Article’s main body. In the context of global digitalization, the scale and pace of digital transformations associated with the emergence of new digital objects, their active involvement in civil, economic turnover and subsequent market turnover are growing. Virtual assets/cryptocurrency are one of the objects in relation to which there has been a bivalent attitude since its appearance, and in relation to the legal nature of which a unified approach has not been formed to date. This article discusses the first official explanations in Ukraine on the nature of virtual assets / cryptocurrencies, as well as the position of the Office of Effective Regulation (BRDO) and theoretical and legal approaches to this object. Qualification features are analyzed, which contains the legislative definition of “virtual asset”, which together represent its functional heterogeneity. Some issues related to the contractual basis for the circulation of virtual assets / cryptocurrencies are highlighted, and suggestions for further development of the current legislation on these facilities are provided. Conclusions and prospects for the development. Legislative legalization of the concept of “virtual assets” is an important step towards the legalization of the virtual assets market and the first stage of the institution of virtual assets, further development of which requires intensification of work on the development of relevant legislation on virtual assets. connection with the generation (issue) and circulation of virtual assets. At the same time, achieving a synergistic effect in the legal regulation of relations, the object of which are virtual assets/cryptocurrency, necessitates appropriate amendments to the Commercial and Civil Codes of Ukraine, the Law of Ukraine “On e-commerce”, tax, investment legislation and more.

Introduction. The digitalization of the financial sector leads to the transition to blockchain technology, which opens up additional opportunities for expanding the financial base of the state through fiscal mechanisms, and generates additional risks. That is why the topic of taxation of the digital sector is now being addressed both at the governmental level and by a number of scientists and crypto enthusiasts.The relevance of the topic presented in the article is determined by the need to determine the legal status and legalization of cryptocurrencies in Ukraine in the system of modern payment and exchange transactions. Methods. Methods of analysis of foreign taxation practice and regulation of cryptocurrency circulation and determination of tax base are used in the process of preparing the article, as well as approaches to interpretation of cryptocurrency from the positions of goods, property, digital financial asset, intangible asset. Results. The results of the study showed that Ukraine has approaches that are based on domestic legislation, or rather its opportunities for expansion in order to conceptually adopt the cryptocurrency industry in the current legal field, and to study foreign experience and practice of leading countries that are already taxing transactions with cryptocurrencies on the general principles of tax legislation, or create privileged conditions in the form of reduced rates or a preferential tax period. Discussion. The difficulty is to find a balance of interests between the state and the user of cryptocurrencies, and it is essential to determine the status of legalization of digital financial assets and digital currencies for the digital economy, which will expand infrastructure and ecosystems in cryptocurrency projects. And scientific approaches will allow to integrate them into the economic system of the country. Keywords: blockchain, cryptocurrency, cryptocurrency, digital goods, taxation, legal status, tax norms

Introduction. The article gives a critical assessment of the situation and discusses the problematic aspects and perspectives of the institutionalization of cryptocurrency. Given the growing public interest in cryptocurrencies circulation, stock market trends, benefits and opportunities for the economy, as well as the associated threats and challenges, regulatory policy and the legislative framework are imperative. It is impossible to solve the problem of legal, accounting and tax consequences of cryptocurrency transactions without determining the legal status of a cryptocurrency. The lack of standards and clear recommendations of the relevant methodological authorities necessitated the search and systematization of international accounting, financial reporting and taxation practice on cryptocurrency transactions. Methods. The authors applied the dialectical method of cognition and general scientific principles of complex research, which include empirical, general logical, theoretical and cognitive methods. These methodological tools are used to identify approaches, assess trends in cryptocurrency circulation and cryptocurrency market, consider the nature and disclosure of cryptocurrency, identify methodological problems of integration of cryptocurrency and related transactions in the system of accounting and financial reporting, differentiation of approaches to determining legal status. Results. Undoubtedly, cryptocurrency has potential. However, to realize this potential, stimulate the growth, increase the accessibility and the level of trust, effectively scale of the business and its interaction with regulatory authorities, it is necessary to create a more institutionally friendly environment. Without appropriate legislative regulation of circulation and determination of the legal status of cryptocurrencies, as well as in the absence of clear recommendations of methodological bodies in the field of accounting and taxation, many legal, theoretical, and applied issues of accounting and taxation cannot be resolved. Discussion. Domestic lawmakers, regulators and scientists have to analyze actively the experience of other countries, to study scientific developments and to conduct further research in order to normalize these relations in the European and global context.

Pursuing the purpose of effective functioning in today's conditions, the business is forced to transform rapidly, to modernize at all levels. The world is changing, erasing the limits of its certainty. Companies need quality trans- formations and strategies that are effective in the face of rapid change towards "deep" digitization. Massive corporate management systems increasingly need the flexibility to keep pace with change. And companies with an innovative cul- ture are more in need of creative tasks than implementing detailed regulations. In the post-industrial time of digital economy, issues related to the development of the information sphere, the media and communications, the usage of modern information systems to develop the economy and stabilize social development as a whole, come first. The basic principles of practical application of Block- chain are investigated in the work. The stages of development of Blockchain technology, the stages of development of Blockchain technologies by time, the application of distributed registry technology in Blockchain applications, the principles of construction and operation of Blockchain have been specified. The benefits of using NEM for business are substantiated and the components of Proxima X technology, protocols and service layers, on-line and off-line proto- cols, decentralized applications are exposed.

Problem setting. In modern conditions special consideration is attracted to the global discussion related to the nature and unshadowing of cryptocurrencies. One of the most relevant topics for discussion in the cryptocurrency space is the future legal regulation of this sphere and the necessity of tight control of financial institutions in the cryptocurrency trading. Nowadays on the territory of Ukraine the legal regulation of the cryptocurrency sphere remains unresolved, effective legislative changes have not been adopted yet. However, some consensus has already been reached on the territory of the European Union in the field of the legal regulation of cryptocurrencies reformation, which causes unconditional interest for Ukrainian scientists and businesses. Based on the stated above, the purpose of the article is to analyze the legal regulation of cryptocurrency unshadowing in the European Union in order to identify the most effective mechanisms for its adaptation into the domestic legal framework. Analysis of recent researches and publications. Some aspects of the legal regulation of the domestic legislation reformation in the sphere of cryptocurrencies have become the subject of scientific research of such authors as Burkovskaya A. V., Varnavsky A. V., Vasilevskaya L. Yu., Kravchenko L. M., Kud A. A., Kucheryavenko N. P., Lizunova A. N., Lunkin T. I., Perebinis M. G., Smychok E. N., and others. At the same time, comprehensive studies of the European Union legislation innovations in the sphere of the cryptocurrency unshadowing and the impact of the reformed legal EU regulation on national legislation of Ukraine is not carried out, that fact actualizes the theme of the article and further research and development. Article’s main body. European leaders today have reached the consensus on the issue that innovative technologies, which are the basis of cryptocurrencies, have the potential to increase the efficiency of the financial system and the economy as a whole, both at the national level and across the European Union. At the same time, European experts have not yet formed a unified approach to the nature and legal status of virtual currency. Scientists argue that increasingly virtual (fiat) currencies are used to finance terrorism through transaction anonymity, so the European Union introduces additional monitoring of virtual currencies and transactions, legalized in Directive (EU) 2018/843, which was analyzed in the article. Repeated attempts to legalize digital assets in Ukraine were made by the legislator, however, none of the bills has been adopted and so far the only regulatory act that would resolve the issues of the cryptocurrencies’ legalization and effective measures to unshadow them have not been adopted, which, in turn, requires the intensification of the legislators’ activities, given the rapid development of cryptocurrencies and innovations. Conclusions and prospects for development. The study showed multivariate interpretations of the legal text of the Directive (EU) 2018/843 by member-countries, as well as the presence of a hidden control regime that goes beyond the needs of the document. At the same time, the Directive (EU) 2018/843 is intended to become an effective regulator of legal relations in the sphere of cryptocurrencies and requires its gradual implementation in the legislation of Ukraine in order to fulfill the international legal obligations of our state.

The article reveals the economic essence of cryptocurrency as an information and technological innovation. The authors have determined that cryptocurrency is a universal global means of payment, exchange, and investing, which exists in the form of a highly protected software code and is characterized by a free market exchange rate. Having considered technical, technological, and organizational aspects of using cryptocurrencies, the authors carried out the comparison of electronic money and cryptocurrency. The done analysis of markets and types of cryptocurrencies has enabled to form a ranking of cryptocurrencies by level of capitalization. The article describes the dynamics of the growth of cryptocurrency market capitalization and the domination of a Bitcoin’s market share. The authors have ascertained strengths of Bitcoin, which had allowed this cryptocurrency to become a useful international means of payment with the high investment potential. The article examines weaknesses of the exchange of cryptocurrency both ordinary consumers and governments. The authors have proven that institutionalization ensured by the formal and informal establishment of rules for functioning of cryptocurrency is necessary for effective functioning of cryptocurrency. The authors have substantiated three positions of institutional support describing the attitude of countries to functioning of a cryptocurrency market: a loyal position, categorical position, and position of anticipation. The authors have developed an organizational and economic mechanism for forming a cryptocurrency market based on functions, methods, and tools of management and suggested directions for undertaking a policy in the sphere of functioning of a cryptocurrency market for countries with the position of anticipation. The process of virtualization of modern society is inevitable. Сountries with the position of anticipation should support the course on innovation by solving a range of regulatory, technical and information issues on the development of the cryptocurrency market, based on leading international experience. The primary tasks should be: granting the legal status of cryptocurrency and developing rules for its circulation, introduction of technological innovations with the participation of the state, large corporations and venture funds, creation of an open ecosystem for interaction of all participants, as well as wide information support at all levels.

We have established that a relatively new market of cryptocurrency is the subject of great interest for research under the current conditions of financial innovations in payment services. Our findings have revealed objective prerequisites for creating cryptocurrency as an innovative means of information-based payment. Cryptocurrency poses a challenge to the financial system of Ukraine since both the central bank and other state regulators can not control its emission and circulation. They show the growth dynamics in cryptocurrency market capitalization where Bitcoin predominates. Although cryptocurrency is not included in the National Register of payment systems and it is officially prohibited for circulation in Ukraine, our country ranks among the world’s top five countries by number of users of different bitcoin-wallets.
 We have examined the strengths of Bitcoin that have made this cryptocurrency a convenient means of international payment with a high investment potential. The results show disadvantages to using cryptocurrency for both the whole country in general and ordinary consumers in particular. We have defined main threats that national governments can face in case of an unregulated spread of cryptocurrency. Also this study, based on the works of leading foreign scientists and financial market experts, systematizes factors that influence the price of Bitcoin. It substantiates opportunities and prospects for the cryptocurrency market development in Ukraine.
 The study has shown that cryptocurrencies have their own niche in payment systems; they are quite competitive and reliable financial instruments. The growth dynamics of cryptocurrency market capitalization in the world makes Bitcoin the most successful example of the use of virtual currency in the information economy. As the modern society is being inevitably virtualized, our country’s economy should follow the path of innovations by finding solutions to a number of technical, economic and legal issues on the cryptocurrency market development in Ukraine through involving the experience of the leading European countries.

The article is devoted to the analysis of transformation of economic relations due to the emergence of such phenomenon as cryptocurrency. It is substantiated that its appearance is connected with the development of the information society, the formation of the virtual economy and the spread of digitization processes in all spheres of economic activity. It is proved that despite the innovative nature of the revolutionary character and the considerable potential for stimulating radical changes in the sphere of economic relations and economic model of modern society, the cryptocurrency is a confirmation of the evolution of money. From the point of view of the theory of money, the ability of cryptocurrency to perform the functions of money (measures of value, means of payment and medium of exchange, accumulation, world money), as well as new specific functions — social, regulatory, indicative and others, — have been proved.
 Analysis of the practice of cryptocurrencies spread gave the opportunity to reveal their characteristic features on grounds of the format of money, unit of account, legal status, money creation, stability of payment, mechanism of exchange, regulation and supervision, risks, etc. In addition, the positive properties of cryptocurrencies and their possible negative effects are identified.
 It is emphasized that the adoption and active spread of cryptocurrencies leads to the transformation of economic relations, and more precisely, the objective formation of a new system of economic relations as a compensator of the negative manifestations of a modern economic society, which, at the same time, has exacerbated to some extent the threats to the traditional monetary system. This is confirmed by the tendencies of the development of the cryptocurrency market, changes in the position of the central banks of the countries of the world from rigid rejection to the development of national cryptocurrencies, including in Ukraine.
 The problematic aspects of determining the legal status of cryptocurrencies in the regulation of cryptocurrency in Ukraine from the point of view of civil-law relations and relatively criminal-law context have been identified.

Стаття присвячена сутності та порядку відображення в бухгалтерському обліку операцій з криптоактивами суб’єктами господарювання в умовах розвитку світової економіки. Розглянуто криптовалюту як різновид цифрових грошей. Охарактеризовано найвідоміші види криптовалют та стан криптовалютного ринку протягом 2019 року. Розглянуто правове регулювання криптовалюти в різних країнах. Окрему увагу приділено питанню визнання та нормативно-правовому регулюванню обліку криптовалюти в Україні. Встановлено, що криптоактиви можуть бути оприбутковані на баланс суб’єкта господарювання шляхом придбання, отримання як засобу платежу за продукцію, товари, роботи та послуги, набуті внаслідок інвестицій на ринку криптовалют та одержані самостійно внаслідок криптовалютного майнінгу. В процесі дослідження доведено, що криптоактиви потребують методичного та теоретичного обґрунтування в умовах нестабільності діючого законодавства. Запропоновано здійснювати облік криптоактивів за допомогою міжнародних стандартів фінансової звітності. Описано принцип роботи блокчейну та наведено переваги використання цієї технології як самостійної системи для ведення бухгалтерського обліку криптовалюти.
