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?
If I were in their shoes before the war, it’s much better to engrave the phrases in indestructible metal bars of any kind as it is resistant to fire, water or any calamity.
I wouldn’t count on saving my seed phrases online and/or in my hard drive, USB, etc. I would rather invest a safe box that is indestructible and keep it somewhere safe along with my phrases and other important stuff regardless of the calamity that I am encountering.
But no matter what, surviving is always my first priority even if I would lose all of my access in my assets because I can get it back anytime I want.
