This paper examines the relationship of the leading financial assets, Bitcoin, Gold, and S&amp;P 500 with GARCH-Dynamic Conditional Correlation (DCC), Nonlinear Asymmetric GARCH DCC (NA-DCC), Gaussian copula-based GARCH-DCC (GC-DCC), and Gaussian copula-based Nonlinear Asymmetric-DCC (GCNA-DCC) Under the high volatility financial situation such as the COVID-19 pandemic occurrence, there exist a computation difficulty to use the traditional DCC method to the selected cryptocurrencies To solve this limitation, GC-DCC and GCNA-DCC are applied to investigate the time-varying relationship among Bitcoin, Gold, and S&amp;P 500 In terms of log-likelihood, we show that GC-DCC and GCNA-DCC are better models than DCC and NA-DCC to show relationship of Bitcoin with Gold and S&amp;P 500 We also consider the relationships among time-varying conditional correlation with Bitcoin volatility, and S&amp;P 500 volatility by a Gaussian Copula Marginal Regression (GCMR) model The empirical findings show that S&amp;P 500 and Gold price are statistically significant to Bitcoin in terms of log-return and volatility
