Wikipedia and Cryptocurrencies: Interplay Between Collective Attention and Market Performance

Abstract

The production and consumption of information on Bitcoin and other digital-, or crypto-, currencies have grown, along with their market capitalization. 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 to digital currencies in Wikipedia and their market performance. We consider the entire edit history of currency-related pages and their views history from July 2015. First, we quantify the evolution of cryptocurrency presence in Wikipedia by analyzing the editorial activity and the network of co-edited pages. We found that a small community of tightly connected editors are 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 than baseline strategies, in terms of returns on investment, for most of the covered period, although the "buy and hold strategy" dominates during the periods of explosive market expansion. Our results contribute to the recent literature on the interplay between online information and investment markets, and we anticipate that it will be of interest for researchers as well as investors.

Mapping the NFT revolution: market trends, trade networks, and visual features

“…We also did not consider collective attention as measured e.g. from social media or Wikipedia, which can be a further source of information about market behaviour 37 – 39 . Fourth, we considered mostly the Ethereum and WAX blockchains, but several other platforms offer smart contracts and NFTs.…”

Effects of COVID-Induced Public Anxiety on European Stock Markets: Evidence From a Fear-Based Algorithmic Trading System

“…Dickerson (2018) demonstrated a very successful algorithmic trading method for trading Bit-coin based on Wikipedia and Google search traffic. ElBahrawy et al (2019) discovered that, when compared to baseline methods, a basic trading strategy based on Wikipedia's opinions on digital currencies provided substantial returns on investment. The third hypothesis to be investigated, based on the literature, is as follows: H03: A Google Trends and Wikipedia-based algorithmic trading system may provide significant advantages.…”

Crypocurrency co-investment network: token returns reflect investment patterns

“…A growing body of literature has so far focused on the properties of the rapidly evolving crypto market ecosystem, shedding light on critical aspects such as market efficiency [8,9], asset pricing bubbles [10], the dynamics of competition between currencies [11,12], and the impact of collective attention [13]. Given the digital and decentralised nature of crypto assets, a major focus has been to understand the drivers of price fluctuations and how to properly value these assets.…”
