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?
Actually in this case I think the title doesn't really fit the context because after all this is just a condition where we imagine in a war situation and your context is not Israel with Palestine because in the end this is just when your PC is broken or whatever.
Answering that is quite obvious when you lose the phrase and can't remember the seed phrase that you have then it is certain that we will lose the access that we have to enter the wallet. This is not referring to war only but in any condition when your PC crashes and your wallet is embedded in it when you lose the seed everything will be lost and cannot be restored.
