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 you saved the one with the seed phrase as your backup, you can still recover it after the war, for sure. But if you don't know where you put it, there is definitely no chance for you to recover it.
That's why it's really important that you have backups, not just one; you should have many backups to make sure that you can also recover when you suffer from such a battle with every country in the world.
