The fiat will kill itself off. Since gold, silver and oil are now fiat, through futures suppression and supply manipulation, only bitcoin survives.

Bitcoiners will be the last alive, in bitcoin friendly countries, with bitcoin payed infrastructure and commodities. 

Bitcoin did not exist in the previous global conflicts. To ignore its affect as a third option is as naive as the claim it will stop the collapse. 

It won't stop the collapse, the way a life boat does not stop a sinking ship.
