The introduction section highlights the potential exploitation of financial technology, particularly cryptocurrencies, for terrorist financing, emphasizing the need for empirical research on the involvement of political extremist groups, such as right-wing extremists. Despite theoretical arguments suggesting vulnerabilities in the financial system, limited empirical evidence exists on the extent of cryptocurrency funding within these groups. The chapter aims to address this gap by conducting the first empirical analysis on the financing activities of extreme right-wing groups in the United States.
