How do you intend to use your bitcoin? Is it completely worthless?
The good thing about it is when war broke out in your country, and everything is in the chaos that you couldn't even bring some money with you because the looters are all over the place, you have the option to keep it in a wallet and just memorize the phrase seeds and other important details to get it back once it back to normal. You can walk in the city naked pretending to be a homeless man without anything but in reality, you are one of the rich human beings that has kept their assets securely than keeping them in the bank.
Though at times internet not yet still available, there is a chance that we will need to experience being broke if there is no way to convert any amount to fiat. Thou hopefully at that time we will wish that there is a money left in our pocket or atleast a chance that there’s a place uphigh that we can reach to have a internet connection. Nevertheless, we should act first to atleast have a fiat the moment we realize that there might be a upcoming war like what happened in Ukraine atleast have some cash when you heard the news and buy the necessities as much as possible.
