Technological progress have affected the methods of financing terrorism and forced its transformation. Among these cases is the financing of terrorism through cryptocurrencies, which has become a new challenge in combating terrorist financing. Accordingly, while examining the concept and nature of terrorist financing, we will discuss how cryptocurrencies have affected the financing of terrorism. This research is applied in terms of purpose and in terms of collecting information through documentary methods and through the study of reliable laws and sources, and the information obtained has been analyzed in a descriptive-analytical manner. Countering the financing of terrorism through cryptocurrencies can include supporting the domestic financial system of countries, enacting strict and precise domestic laws, focusing on the bottleneck of converting virtual currencies into each other and converting virtual currencies into real currencies, especially in the case of terrorist financing, and finally, adopting uniform procedures at the international level and police cooperation and legal assistance. Current research on digital currencies in terrorist financing is in its early stages and, without considering the issue of digital currencies in terrorist financing, focuses on analyzing the financing tools, motivations, and terrorist acts.
