If military attacking ur home ur gold or silver even house will be gone most likely the bank building gone all the local structures gone only thing is left crypto its in the internet it does not have o ne speficic location
Except Internet connection will also be gone in areas close to the front lines and occupied territories, so you won't be able to use crypto while there (and don't start with satellite Internet - it's not available everywhere and can theoretically be jammed). Also, Bitcoin adoption for payments is not widespread, so while you are in such extreme conditions, you will need to find ways to convert it into fiat - which could easily be impossible.
A "smart" thing to do is to have enough cash to survive, and store your wealth in Bitcoin. Providing that you can manage it properly and not lose it all because you had only one copy of your seed and it's gone for some reason.
But I would say, in general Bitcoin is not a good asset for a crisis. If you have lost nearly all your physical possessions, and then Bitcoin crashes by 20-50% for no reason, and your only choice is to sell Bitcoin, even at a loss, just to survive - that's not a good deal. It could be used to smuggle your wealth across the border or military checkpoints, but after that it's better to convert it back to fiat once you are safe.
