FACTORS INFLUENCING BITCOIN MARKET VOLATILITY DURING THE COVID-19 PANDEMIC CRISIS

ABSTRACTThe ecological structure of the cryptocurrency market and its external environmental impact cannot be ignored. Taking Bitcoin as an example, the study analyzes the Bitcoin market during the COVID-19 pandemic crisis from an environmental perspective based on the differences in the political and economic systems of China and the United States. First, the institutional environment selected in this study is used as an indicator of environmental measurement and divided into formal and informal sectors. In the analysis, the former selects the economic policy uncertainty index of China, while the latter selects bitcoin's social attention (including Google trends and the Baidu index) and investor sentiment as indicators. Second, financial market data such as foreign exchange and commodity futures are used as indicators for analyzing the environment of the bitcoin market. Using VAR modeling analysis, the results show that both the institutional and the market environment have an impact on bitcoin's market performance.KEYWORDS: Bitcoineconomic policy uncertaintysocial attentioninvestor sentimentCOVID-19 crisis Disclosure statementThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.Additional informationFundingThis work was supported by the [Shanghai "Super Postdoctoral" Incentive Program] under Grant [number 2021175]; [Project of Philosophy and Social Science Research in Colleges and Universities in Jiangsu Province] under Grant [number 2021SJA1096]; and [Special Foundation for Science and Technology Program (Soft Science Research for Innovation Support Program) of Jiangsu Province] under Grant [number BR2022011].Notes on contributorsZhunzhun LiuZhunzhun Liu is currently a postdoctoral fellow at the Post-Doctoral Research Centre of the Shanghai Gold Exchange, which is a joint postdoctoral programme with the School of Management of Fudan University.
