The war has started and crypto is going to see a huge boost. India and Pakistan, both a highly populated country and India has a huge population who uses cryptocurrency or regularly invest in it. So when the stock market falls, people will move their assets to Bitcoin or some other good cryptos.
I don't believe that the war between these countries would be a bullish event. Also, why would people buy Bitcoin (if the stocks are declining) in the time of war? People would prefer to take precautions and measures to survive themselves and don't care to keep an eye on the market or buy crypto or stocks. Rather, I would say that some of the people may sell crypto to buy excessive food and other life saving items. The day-to-day necessary items may get in short supply, so people would prefer to be in cash rather than in risky assets.
