In the context of the widespread digitalization of society, cryptocurrency has become particularly popular due to its progressiveness and innovativeness. Its characteristics, such as cross-border accessibility, decentralization, anonymity, high transaction speed, and low costs, attract users. However, some of these features pose significant security risks, not limited to the financial sector. As a developing and ambiguous phenomenon, cryptocurrency requires special attention from states. Countries adopt various policies regarding it, ranging from total prohibition to full authorization. A striking example of a restrictive policy is China, where authorities are gradually limiting cryptocurrency to minimize risks and protect the digital yuan. Japan, in contrast, appreciates the progressiveness of this digital asset and its potential in the era of digitalization. To reduce risk, Japan has established a system of self-regulation for cryptocurrency, employing certification and identification mechanisms. Attitudes toward cryptocurrency, its legal status, and regulatory measures vary significantly between countries. For more effective regulation, the development of common supranational standards, norms, and mechanisms is necessary.
