Abstract: The subject of the study is the dependencies, trends and key features of the turnover of cryptocurrencies as a separate phenomenon. The purpose of the study is to analyze the key features of the cryptocurrency turnover and the problems of their legal regulation, followed by the development of practical proposals for the prevention of cryptocurrency crime. The objectives of the research are: analysis of modern technologies related to cryptocurrencies; their features and degree of influence on financial markets; problems of prevention and legal regulation of cryptocurrencies in Russia. The object of research is formed by public relations related to the use of cryptocurrencies in the financial market. Cryptocurrencies represent one of the most significant phenomena in financial technology. In the context of globalization and digitalization, they provide new opportunities for transactions, investments and storage of funds. However, the rise of decentralized finance, anonymous wallets, and NFT scams has turned blockchain into a "new shadow" of the global economy. This confirms the importance of developing new techniques and means of preventive activities of law enforcement agencies. The methodological basis of the work is the method of dialectical cognition, thanks to which it was possible to study the object and subject of research in relation to the domestic criminal legislation and other normative legal acts. The theoretical and methodological basis of the research is various logical techniques and means of scientific knowledge, general scientific and private scientific methods: modeling, forecasting, formal legal. The novelty of the study is due to the analysis of modern official statistical data and materials of investigative and judicial practice on the state of cryptocurrency crime in Russia. The study of domestic legal acts in the field of the use of financial assets allowed us to conclude that the status of cryptocurrencies is uncertain. The authors summarize that cryptocurrency crime does not require prohibitions, but a rethinking of law, because it is not technology that poses a threat, but its exploitation in conditions of legal inequality. The main conclusions obtained by the authors relate to determining the financial characteristics of cryptocurrencies, their volatility, liquidity, and risk assessment of use. The trend of increasing demand for the integration of cryptocurrencies into traditional financial systems has been proven. The problems of legal regulation and regulatory consolidation of the concept of "cryptocurrency", including in domestic criminal legislation, are outlined. The main reasons for the spread of cryptocurrency crime and the prospects for preventive activities of investigative authorities based on the capabilities of artificial intelligence have been identified.

Abstract: The subject of the study is the regulation of actions of special units for escorting convicts and persons in custody during the commission and suppression of escapes. The purpose of the work is to identify the main problems faced by the staff of the guard service and suggest ways to solve them in order to improve the efficiency of the functioning of special escort units in the context of modern challenges of reality. The methodological basis of this work is dialectics, induction, deduction, analysis, formal logical, formal legal, statistical methods, as well as the method of normative legal analysis. The research paper analyzes the concept and tasks of special escort units, the main problems and challenges they face, and criminal schemes based on established law enforcement practices used by convicts and detainees to escape during escort. The results of the work show that escapes pose a serious public danger and can be associated with diverse crimes. The main methods of escape are outlined, as well as shortcomings in the organization of security, training and interaction between law enforcement agencies. The scope of the results includes the practical use of the proposed recommendations to improve the efficiency of the escort units, as well as the development of new approaches to ensure the normal administration of justice. The conclusions that were formulated in the work emphasize the need for an integrated approach to solving the problems of escorting, including the use of modern technologies, the training of highly qualified personnel in convoy units and methods of monitoring the work of employees, which will significantly increase the level of public safety and reduce the risk of escapes.

Abstract: In order to carry out the tasks facing the criminal law, norms are provided in advance that have an encouraging character, but at the same time stimulate law-abiding behavior in the form of stopping preparations for committing a criminal act. Such an example is the institution of voluntary refusal to commit a crime and bring it to an end both alone and in complicity. At the same time, this category makes it possible to achieve one of the goals of criminal law – the prevention of crime, however, provided that the voluntary refusal becomes voluntary, timely and final. The subject of the presented research is the criminal law norms governing legal relations related to the voluntary refusal of complicity in a crime. The purpose of the study is to analyze the features of voluntary refusal to participate in a crime.The scientific research work analyzes the concept, signs and criminal law significance of voluntary refusal to commit a crime in complicity. The results show that group crimes, due to their prevalence, require a deeper study and development of theoretical foundations, legislative regulation and practical aspects for the correct legal assessment of such acts. The scope of the results is aimed at developing a separate legal norm devoted to the peculiarities of voluntary refusal. The scientific novelty of the study is expressed in the identification of special patterns and problematic aspects in the field of differentiation of voluntary refusal to commit a crime by the organizer, perpetrators and other accomplices.The conclusions emphasize the need to introduce a separate legal norm that will more effectively regulate the legal aspects of complicity, avoid mistakes in qualifying the voluntary refusal of accomplices from completing the crime, as well as ensure justice when bringing to justice participants in a group crime.
