  This survey develops a dual analysis, consisting, first, in a bibliometric
examination and, second, in a close literature review of all the scientific
production around cryptocurrencies conducted in economics so far. The aim of
this paper is twofold. On the one hand, proposes a methodological hybrid
approach to perform comprehensive literature reviews. On the other hand, we
provide an updated state of the art in cryptocurrency economic literature. Our
methodology emerges as relevant when the topic comprises a large number of
papers, that make unrealistic to perform a detailed reading of all the papers.
This dual perspective offers a full landscape of cryptocurrency economic
research. Firstly, by means of the distant reading provided by machine learning
bibliometric techniques, we are able to identify main topics, journals, key
authors, and other macro aggregates. Secondly, based on the information
provided by the previous stage, the traditional literature review provides a
closer look at methodologies, data sources and other details of the papers. In
this way, we offer a classification and analysis of the mounting research
produced in a relative short time span.
