Hugo Estecahandy is a graduate of the Master’s degree of the French Institute of Geopolitics (Cyberstrategy & Digital Terrain course) and of the Magisterium of History and Geopolitics of Contemporary Eurasia of the Russian State University of Humanities (RGGU) in Moscow. Since November 2020, he has been preparing a thesis on the development and challenges of cryptocurrency mining, with the Irkutsk region in Eastern Siberia as the main case study. By studying the subject through a geopolitical approach, the objective is to analyse the location factors (energy, climate, technical, …), the diversity of actors and the multifaceted repercussions of the development of this industry, at different scales. The growing use of cryptocurrencies and the development of their creation industries on an industrial scale raise social, economic and security issues, and require a multidimensional geographical approach (physical space, cyberspace).
