Digital currencies have been developed only after the global recession in 2008. Therefore, there is only little knowledge about the behavior of cryptocurrency during financial crisis. This study will examine if the return volatility of cryptocurrencies in pre-COVID-19 and COVID-19 periods caused any differences in returns. The ten most traded cryptocurrency market returns are examined in this study using the ARMA-EGARCH model to determine the impact of return volatility both before and during the COVID-19 epidemic.
