This paper examines the dynamic conditional correlations among 10 cryptocurrencies and the possibility of hedging investment strategies among multiple cryptocurrencies over the period affected by COVID-19 from 2017 to 2022. After studying the relationship between Bitcoin, Ethereum, and the other eight cryptocurrencies, four main results were obtained in this paper: first, from the pre-COVID-19 period to the COVID-19 period, almost all of the cryptocurrencies’ return growth rates increased, and COVID-19 had a positive effect on the returns of cryptocurrencies. Second, all of the cryptocurrencies’ return indices had features of volatility clustering and memory persistence in the long run; from pre-COVID-19 to COVID-19, these cryptocurrencies’ GARCH values decreased, but the correlations among the varying GARCH values increased. Third, the varying correlations between the return indices of Bitcoin, Ethereum, and the other cryptocurrencies were very strong; from pre-COVID-19 to COVID-19, the average dynamic correlations between Bitcoin and the others increased. Fourth, Tether can be used as a hedge cryptocurrency against the other cryptocurrencies as COVID-19 enhanced its hedging feature.

This is the first survey conducted in China on the holding of cryptocurrencies. Although cryptocurrencies have existed in the world for more than a decade, because the exchange of cryptocurrencies is banned in China, there is no guidance on the holding of cryptocurrencies in China’s accounting standards. Moreover, although the exchange of cryptocurrencies is prohibited by the Chinese government, holdings of cryptocurrencies by Chinese entities and individuals cannot be prevented. Thus, we conducted a survey in investors’ attitudes towards cryptocurrencies in Xiamen City, a special economic zone (SEZ) and a pilot free trade zone (FTZ) in China. The survey respondents commonly defined cryptocurrencies as investments (45%), inventories (19%), and intangible assets (36%). A total of 84% of respondents stated that the value of a cryptocurrency should be represented by a fair value. These results are similar to those obtained in a survey by The Digital Assets Accounting Consortium (DAAC), but different to the tentative agenda decision of the International Financial Reporting Standards Interpretations Committee (IFRSIC). Additionally, 65% of respondents stated that they prefer to accept cryptocurrencies as cash equivalent currencies, and these cash equivalent currencies were considered to have two main functions: a medium of exchange (56%) and a monetary unit for pricing goods and services (52%).
