of course WW is bad for economic and humanity, but this thing can turned bitcoin to be main currency, why?
because bitcoin is pure decentralization, no people can reject transaction, no goverment can stop it
Do you think WW III will be similar to the wars that took place in 1914 or 1939? In the event of such a war, casualties would be in the hundreds of millions and infrastructure would be one of the main targets of the attack. Internet is required for transactions, if it is gone or limited, BTC becomes pretty worthless.
Count on war as a means of adaptation is really ridiculous, even if price is go up to $1 million per BTC, atomic bombs, chemical and biological weapons are not an environment where money can be spent...
