<p>This paper investigates the impact of the Russia-Ukraine war on fluctuations in eight prominent cryptocurrencies. Given their inherent volatility, cryptocurrencies have become an important area of study for understanding how global crises affect financial markets. Using advanced dynamic and asymmetric modeling techniques, this study examines the interdependence and asymmetric volatility of these digital assets. By analyzing how cryptocurrencies respond to the uncertainty and shocks generated by the conflict, this research aims to provide insights into their behavior as alternative financial instruments during geopolitical instability. Our findings reveal a negative impact of the war on cryptocurrencies such as Cardano, Dogecoin, Tether, and XRP, while Bitcoin, Litecoin, BNB, and Ethereum experienced a positive impact. These results highlight the varying vulnerabilities of cryptocurrencies and suggest that assuming constant correlations is inadequate. This necessitates further exploration of conditional correlation dynamics to better capture contagion effects during geopolitical events. The study also discusses the implications of these findings for investors, policymakers, and regulators, emphasizing the importance of considering external factors, like geopolitical events, in investment decision-making and the development of regulatory frameworks for the cryptocurrency market.</p>
