Wars happen because countries can't pay up their debts, so they "pay up" this way. (Again, in my opinion, no misunderstandings)
In a war, the fiat loses its value. I had a discussion with a friend about what could happen to bitcoin in a war. He said that it will surely collapse. I am not so sure about it.
Although, think about it for a while. In a world war, the last thing someone has is access to the internet. Would bitcoins lose their value?
History has shown that gold is the money that "reborns" fiat. At least after a war. I would like to read some thoughts.
You made a good discussion. As like dollars, bitcoin is also based on Market.The value of dollar was reduced in world war is due to the Market. The price of bitcoin is decentralized one, it mean no one can control it. It was only done by the investors and traders. I hope we don't face any next world war, because no country work with diplomatic tactics. Surely world war will affect the world economy badly. So all the country should not encourage it again.
