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 ?

That's a very interesting question. First of all, of course, the system would need to still be running, and I assume little effect done to those who use and accept it.
If that's the case, it may well rise in value, but I think precious metals would probably fair better. But who knows.
If that's not the case, and the system is still in place, but the infrastructure has been severely damaged, then the price might go down.
Of course, it might also depend on who is using it and for what. If whales are using it to transfer wealth from one place to another, that might cause the price to temporarily go up.
But again, who knows, we'll have to see, unfortunately.
Have a good day,
