Cognitive warfare is the product of the integration and convergence of emerging technologies that have emerged and emerged in the last few years. Given the novelty and multidimensionality of cognitive warfare, the production of useful knowledge in this field is essential. The emerging technology examined in this study is digital currency, which has been very popular with individuals and organizations in recent years due to its high penetration rate in the field of financing and investment. The focus on emerging technologies in the field of financing, especially digital currencies, is increasingly growing in the financial, banking, organizational, and individual sectors. This article examines the role of digital currencies in modern finance and financing organizations and individuals with a cognitive warfare approach. The method of conducting this research is meta-synthesis. In order to perform meta-synthesis on selected articles and reports, there are various methods, and in this article, the seven-step method of Sandelowski and Barroso (2007) has been used. In the first step of this method, after identifying and determining the topic (cognitive warfare), the research questions were identified and then a systematic literature review was started. The sources found were reviewed in terms of title, abstract, and text, and irrelevant articles and reports were removed. First, 43 sources were identified, and then, in four stages and by removing irrelevant sources, 10 reliable domestic (between 99 and 1403) and foreign (between 2021 and 2024) sources were analyzed, and themes related to the financing of emerging technologies were extracted with a cognitive warfare approach and a variety of research methods in this field. The results show that digital currencies offer businesses and individuals the opportunity to reduce transaction costs, increase efficiency, greater security and privacy, significant asset diversification benefits, and alternative financing and financial inclusion solutions. However, there are challenges regarding the integration of digital currencies into finance; including the lack of regulatory standards, the risk of criminal activities, high energy costs and environmental impacts, and high volatility in the price of digital currencies. This review can help researchers and individuals seeking a balanced understanding of these emerging financial instruments, and provide recommendations for managing the associated risks and effectively exploiting the available opportunities. Finally, the paper provides recommendations for investors to be able to exploit these opportunities more effectively.
