The test parameters Johansen co-integration, vector error-correction (VEC) and vector auto-regression (VAR) block exogeneity are employed. Results obtained indicates no long-term connection between BTC and the above mentioned fiat currencies prior to the pandemic, but during the COVID-19 period, a positive long-run relationship has been found between BTC and GBP and negative connection has been found between BTC and INR, MXN, and RUB.
