Abstract
This study utilises the Cryptocurrency Fear & Greed Index (CFGI) to analyse the bidirectional relationship between Bitcoin’s price and market sentiment during the KuCoin exchange heist. The time-varying Granger causality test reveals no significant bidirectional causality before the heist, but a strong bidirectional relationship emerges afterwards, indicating heightened interaction under increased market uncertainty. Furthermore, this relationship does not extend to other cryptocurrency heists unless they have an indirect impact on the Bitcoin market. Finally, the TVP-VAR-based connectedness approach analysis shows that the Bitcoin market panic induced by the KuCoin exchange heist has limited spillover effects on other cryptocurrency markets. Our findings help address gaps in understanding the bidirectional dynamics of the relationship between price and investor sentiment, providing valuable insights for managing Bitcoin trades and cryptocurrency portfolios during extreme market events.
期刊介绍:
The focus of the North-American Journal of Economics and Finance is on the economics of integration of goods, services, financial markets, at both regional and global levels with the role of economic policy in that process playing an important role. Both theoretical and empirical papers are welcome. Empirical and policy-related papers that rely on data and the experiences of countries outside North America are also welcome. Papers should offer concrete lessons about the ongoing process of globalization, or policy implications about how governments, domestic or international institutions, can improve the coordination of their activities. Empirical analysis should be capable of replication. Authors of accepted papers will be encouraged to supply data and computer programs.
