“…System participants started seeing bitcoin is a type of alternative investment, rather than an instrument for making payments. This is also reflected in papers in the field of finance referring to the issue of bitcoin as they often analyse the behaviour of the cryptocurrency's quotations (Kristoufek, 2015;Brandvold, Molnar, Vagstad, Valstad, 2015;Baek, M. Elbeck, 2015;Cheung, Roca, Su, 2015;Ciaian, Rajcaniova, Kancs 2016). The study of available literature on the subject has shown that relatively little attention has been devoted to the use of bitcoin in payments (Polasik, Piotrowska, Wiśniewski, Kotkowski, Lightfoot, 2015;Leung, Dickinger, 2017;Schuh, Shy, 2015) and that the adopted systemic solutions were not perceived as a particularly significant limitation on the basic function of bitcoin.…”
