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?
There's absolutely nothing you will do about it afterwards in as much as you didn't backup your wallet phrase in different locations but in one single piece your assets is lost perhaps for ever. It is for the circumvention such unforeseen circumstances like war, inferno, natural disasters and more that we are advised to multi-locate our private keys.
Like they say, when there's life there is hope, survival is quintessential which actually means you can put in more efforts start afresh to making money again. Moving on may be hard but that's the best option.
In any case, we should not rely only on our computers and other similar devices to store our secret keys to cryptocurrency wallets. I am a proponent of having printed information on paper. Storing in Google's cloud storage is also not entirely reliable, since starting from the new year they set a two-year period after which, if the account was inactive, all information in the cloud drive is erased. Apparently, we need to simultaneously use different methods for storing our keys. But it’s still impossible to predict everything, and many will lose access to their wallets, including because of the war.
