Have you consider that you lose all your coins because the wallet phrase to your coins and PC burn in a war.
So what will you do if you survive after the war to start back your financial struggling and your crypto investment journey. Or can you get the coins back?
There is nothing you can do if you are not conscious enough to keep your wallet seed phrase in a hardware wallet or in something that you can always carry on. At first, it is bad practice to keep your PK or recovery phase only on a computer or laptop. You should keep it in a hardware wallet, or at least in a pen drive if you cannot afford a hardware wallet. You can still lose your hardware wallet or pendrive but the chance of not being lost in a war zone is higher. You can make a tattoo of the seed phrase on different part of your body though this sounds funny in an extreme place like war zone it is not a bad idea because your intention is to keep your wallet secure no matter what.
