With tensions rising between India and Pakistan, how would an all out war between these nuclear powers impact crypto markets and global finance? Short term crash or flight to digital assets?

Oh no, not again.
Aren’t we tired of all these wars, tensions growing here and there… we are still mourning the dead in Ukraine and Russia even as we hope for the war to stop and peace return to their lands, we had Israel and Gaza where the genocide remains one of history and here we are yet again with tensions between India and Pakistan… where is all these bringing us and aren’t these nations seen just what war can do from the much we’ve had!
OP I really hope the war you’ve predicted doesn’t become the case, we’ve seen so much war in such a short time and we don’t need anymore. We want peace for all peoples, let people return to their homes and livelihood, be able to go to the park and have a good time. In the days of peace, we would still have meaningful impact on cryptocurrencies.
It's hard to say, hopefully the situation doesn't end up in armed conflict specially because that is what the US regime wants (I personally believe the Keshmir terrorist attack was CIA's work, there is just too much evidence suggesting it).
A lot of neighbor countries like Iran are already trying to de-escalate the situation and prevent war from breaking out because the last thing we need in our region is a war.
It’s always about them, every time these things come up, you’re always going to find Uncle Sam in it and somehow, the rest of the world never learns from what they’ve had to see what impact and what is left of the people and way of living where these wars are fought.
There after, you get conditioned aid after they had only destroyed you!
