Next war will be nuclear or atomic and that would be the end of world.
I have also started to think about another world war after trump ordered to throw the biggest non-nuclear bomb ever made in afganistan. Who gave him permission to just throw his bombs in land of other's 
USA is digging their nose in internal issues of several countries and they are using those countries as testing ground for their weapons.
The ISIS were hiding in caves. Be thankful that the US didn't decide to nuke the entire area.
If war does come, my biggest concern would be saving my life, not saving my bitcoins.
