Cryptocurrency and blockchain technology have experienced rapid advancement in recent years. Bitcoin, as a representative cryptocurrency, has been acknowledged as a legitimate payment method by numerous countries and institutions, while blockchain technology has significantly matured, particularly in the realm of distributed algorithms and decentralized systems. In this paper, we conduct a bibliometric analysis of relevant studies by using CiteSpace and Pajek, where literature data sourced from the Web of Science (WoS). Through our examination of this literature, we identify that the focal points of research in this technology are the innovation within blockchain platforms and the protection of user privacy. Moreover, in the field of application, we concentrate our analysis on the legal compliance associated with Bitcoin mining.
