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?
I've actually thought about this, though it's not an effective storing technique but I'm left with no choice since I'm constantly on the run for my life. Storing my seed phrase on a piece of paper or metallic steel plate may not be ideal at this point as it could be destroyed. I know I don't support storing of seed phrase electronically but if I happen to be in a country where there's war, I would save it in a cloud storage and if I make it through the war and everything returns back to normalcy. I would look for a computer or phone and access my funds. If it's still in intact, I would create a new wallet, transfer my funds to the wallet and keep my seed phrase offline.
