Like many things when it comes to unexpected events, the damage is often far gone before the average person is able to react effectively and save themselves. For example the value of the Ruble has fallen and many businesses have no interest in Russian users any more because of the actions of Putin. That makes it much harder to cash out at a decent value compared to what peoples savings were worth before the war. It also makes it difficult to cash out any saved Bitcoins going back the other way, both because there are less choices in terms of exchanges and because any cash out will end up in Rubles for living expenses which could drop sharply again at any time. I guess this is the price you pay for having an erratic and unstable leader.
