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?
In this case, if you have seen or been aware or wary that your place does have that in war situation then you should really be that attentive or tending back up everything.
If you do see that if your paper which your keys been written is at risks then its better to store up those PK's on cloud or on email which i dont really that recommended
knowing that exploits and unauthorized access could happen but for the sake of things to be that just in temporary then it wont really be that a bad choice.
You wont really be bothering yourself with those keys and you wont really be that stressing yourself on trying to protect it.
You could always make that access anytime if ever you do need to have that wallet which those pk's being stored neither on an email or whatever cloud storages.
On the time that the war is over then it would really be that right that you should be erasing those pk's then go back into your traditional offline storage or safekeeping
of those keys.
There are indeed situations which it is really that hard specially on war on which everything you do posses might be burned up or would
really be that abandon.This is why physical storages isnt really that recommended this type. They are really that prone on getting lost
or would be burnt out.
