Since 2012, there has been growing interest in bitcoin scientific research from different fields, including computer science and engineering, economics, business and finance, law and regulatory. The purpose of this paper is to evaluate bitcoin literature based on the structures and networks of science, as a first step in the research of this new phenomenon. Analysing the growing scientific literature on bitcoin published between 2012 and 2019, we provided useful insights on academic research in this field regarding publication year, type and category, authors, journals and citations. The source of the 887 documents which support the study was Web of Science Core Collection. Using VOSviewer software we have designed bibliometric maps based on text and bibliographic data. Our study provides a knowledge area map that identifies and evaluates the links between authors and countries distribution, the conceptual structure of the field, the structure and connections of most cited papers and journals. Resuming our findings, we note a concentration of the interest on some keywords (bitcoin, cryptocurrency, blockchain) and on some influential authors (with more than 100 citations per article). As a pure expression of digital economy, the research on bitcoin as an economic concept counts only 33.5% from the total contributions in the field.

The paper analyzes if the international monetary system calls for reform and whether China and the renminbi will play a decisive role in the post COVID-19 world. It also evaluates the main scenarios and trends that is being discussed since the global crisis – selecting the relevant authors, journals, institutions and opinions – examines present conditions and tries to extrapolate into future trends. Opting for a nontechnical approach, the article could be a good insight into the international monetary system, for academics, non-experts and policy makers. The paper concludes that if the 2008 crisis has induced the growth of the China role in the international monetary governance and the increase of the renminbi internationalization, the COVID-19 pandemic and post crisis reconstruction could generate a deeper reform of the international monetary system, in which the Chinese currency will strengthen its global position alongside the US dollar and the euro.
