英文摘要：
  The production and consumption of information about Bitcoin and other digital-, or \'crypto\'-, currencies have grown together with their market capitalisation. However, a systematic investigation of the relationship between online attention and market dynamics, across multiple digital currencies, is still lacking. Here, we quantify the interplay between the attention towards digital currencies in Wikipedia and their market performance. We consider the entire edit history of currency-related pages, and their view history from July 2015. First, we quantify the evolution of the cryptocurrency presence in Wikipedia by analysing the editorial activity and the network of co-edited pages. We find that a small community of tightly connected editors is responsible for most of the production of information about cryptocurrencies in Wikipedia. Then, we show that a simple trading strategy informed by Wikipedia views performs better, in terms of returns on investment, than classic baseline strategies for most of the covered period. Our results contribute to the recent literature on the interplay between online information and investment markets, and we anticipate it will be of interest for researchers as well as investors.

中文摘要：
比特币和其他数字货币（或称“加密货币”）信息的生产和消费与其市值一起增长。然而，对于在线注意力与多种数字货币市场动态之间的关系，仍然缺乏系统的调查。在这里，我们量化了维基百科对数字货币的关注与其市场表现之间的相互作用。我们考虑了货币相关页面的整个编辑历史，以及2015年7月以来的查看历史。首先，我们通过分析编辑活动和共同编辑页面的网络，量化了加密货币在维基百科中的存在演变。我们发现，一个由紧密联系的编辑组成的小社区负责维基百科中有关加密货币的大部分信息的制作。然后，我们表明，在所涵盖的大部分时间内，维基百科观点所提供的简单交易策略在投资回报方面比经典的基线策略表现更好。我们的结果有助于最近有关在线信息与投资市场之间相互作用的文献，我们预计这将引起研究人员和投资者的兴趣。

一级分类：Computer Science        计算机科学
二级分类：Social and Information Networks        社会和信息网络
分类描述：Covers the design, analysis, and modeling of social and information networks, including their applications for on-line information access, communication, and interaction, and their roles as datasets in the exploration of questions in these and other domains, including connections to the social and biological sciences. Analysis and modeling of such networks includes topics in ACM Subject classes F.2, G.2, G.3, H.2, and I.2; applications in computing include topics in H.3, H.4, and H.5; and applications at the interface of computing and other disciplines include topics in J.1--J.7. Papers on computer communication systems and network protocols (e.g. TCP/IP) are generally a closer fit to the Networking and Internet Architecture (cs.NI) category.
涵盖社会和信息网络的设计、分析和建模，包括它们在联机信息访问、通信和交互方面的应用，以及它们作为数据集在这些领域和其他领域的问题探索中的作用，包括与社会和生物科学的联系。这类网络的分析和建模包括ACM学科类F.2、G.2、G.3、H.2和I.2的主题；计算应用包括H.3、H.4和H.5中的主题；计算和其他学科接口的应用程序包括J.1-J.7中的主题。关于计算机通信系统和网络协议（例如TCP/IP）的论文通常更适合网络和因特网体系结构（CS.NI）类别。
