The headlines about the war might look scary, just take a look at it's recent rebound which is still a reminder that Bitcoin is built to endure though time and that's exactly what we love about it and also why people trust it with their investments.
Sometimes crisis didnt pose a negative impact on crypto. Like for example bitcoin during the covid19 situation, its a global threat instead bitcoin do a magnificent run. The war news impacted btc during the first week which probably due to panic selling but afterwards its gone and it immediately recovered and bounce back to a higher price.
Not every economic crisis causes inflation, many crises cause deflation, and governments don't always print money when a crisis occurs. So bitcoin will also react differently in each crisis and bitcoin does not always grow in crises.
During the pandemic, bitcoin and stocks were severely dumped, and they only really rose when the government decided to print money and pump money to save the economy. That means the opposite would happen if the government did not decide to pump money.
Similar to war, bitcoin price also drops when there is news of war breaking out and only really increases again when there is news of a ceasefire between the two countries. But if the war drags on, causing more serious consequences for the economy, bitcoin could continue to fall instead of rise.
But in the long run, bitcoin will adapt and grow regardless of whether the war ends or not, and the war in Ukraine and Russia is an example.
