What cryptocurrencies have been used to help fight a war?

Cryptocurrencies have been increasingly explored for their potential in various unconventional applications, including their role in conflict resolution and wartime scenarios. Given the decentralized and borderless nature of digital currencies, they offer unique opportunities for financing operations and circumventing traditional financial sanctions. So, I must ask, which cryptocurrencies have been utilized to aid in the fight of a war? Have they been used to fund resistance movements, support military operations, or facilitate the transfer of funds in war-torn regions? The implications of cryptocurrencies in such scenarios are fascinating yet complex, and I'm eager to understand their role and significance in the context of modern warfare.
