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, which make unrealistic to perform a detailed reading of all the papers. This dual perspective offers a full landscape of cryptocurrency economic research. First, 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. Second, 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.

我们在哪里进行密码货币经济研究？基于混合分析的调查

这项调查进行了双重分析，首先是对文献计量学的研究，其次是对经济学中迄今围绕加密货币进行的所有科学生产的详尽文献综述。本文的目的是双重的。一方面，提出了一种方法学混合方法来进行全面的文献综述。另一方面，我们在加密货币经济学文献中提供了最新的技术水平。当主题包含大量论文时，我们的方法将变得很有意义，这使得对所有论文进行详细阅读是不现实的。这种双重观点为加密货币经济研究提供了一个完整的视角。首先，借助机器学习文献计量技术提供的远距离阅读，我们能够确定主要主题，期刊，主要作者，和其他宏观汇总。其次，基于前一阶段提供的信息，传统文献综述对论文的方法，数据来源和其他细节进行了仔细研究。通过这种方式，我们对在相对较短的时间内进行的安装研究进行了分类和分析。
