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's nothing you can do. If you have neither the wallet file nor the seed phrase, there is no way to recover the wallet.
It's always recommended to keep multiple copies of your seed phrase in different locations.
For more security, you can consider graving your seed phrase on a stainless steel plate instead of a writing it down on a paper.
What happened if in the war you are force out in rush to survive bullets with no means carrying away with you stainless steel plate of the graving that you make of your passphrase for the coins. What can you do because war and running out to refugee camp has no preparation. I'm looking at the war all over different location and I think of that for people in problem like that.
