Hi ! First message here.
If a global disaster would happen on earth ( And I somehow don't wish it ) Would the value increase or decrease ?
I'm not talking about solar flares or EMP. But more like big wars or great natural disaster.
What are your opinions on the subject ?

There's a possibility that the supply of Bitcoin will diminish since this is a war people will encounter untimely death and loss of properties and there's a possibility that their shares will also lose, there are a lot of people lose their coins even if there is no disaster, what more if there is one
Well it will not affect according to me because I think both if it happens or not but the value of the bitcoin will remain the same as there will be less number of people in the world but still people will need something fast service to use and as fiat has the physical presence so it will get spoiled but as crypto like bitcoin is the digital currency so it will remain the same.
