It really make people safe from any risk on any sanctions or economic intervention that's why its really important to have crypto on their financial system. For sure Russian and Ukrainian government see its importance and might we can see some great changes after this war ends. And maybe this could add some good impact with bitcoin since for sure other country are much aware about bitcoins existence.
When war is over, the world will realize how important cryptocurrency is to a country. If unfortunately fall into an economic crisis, isolated from the outside world due to war, where fiat currency depreciates blocked banks cannot withdraw and transfer money there is no place to safely store assets. Only crypto can be the only solution to help them solve problems that banks and fiat cannot do.
It doesn't really need to be the war to stop to be able to realized how important crypto not just for a country but for every individuals. Just the covid-19 outbreak alone show how good crypto is, or how your money grows through crypto. All we want is that crypto will be just universally accepted and that many stores online or offline are going to accept it so that we can used it anymore without bringing in fiat.
