In the event of war, when the Internet is disconnected, bitcoin will lose all its value, and gold will remain gold. Therefore, it is still more profitable to invest in it.
If we will see some kind of global conflict in the future then your best investment in that case should be food rations, water and armored shelter.
Not gold, other precious metals or stones, fiat money or any kind of cryptocurrency. Realistically lack of internet will take you back to the Stone Age.
If you are worried that war is serious eventuality then Bitcoin is not for you, so pile up your gold bars and wait in your shelter for Armageddon.
IMO it's wise enough to convert bitcoin into gold if major disaster happen espcially bitcoin reach another high value at the moment $ 1.400 ( preev)
I'm usually invest on bitcoin from my main salary and spend about 10% and when I sell my bitcoin , I'm bought gold and/ dollar for another investment
