Their economy may be in shambles if they decide to go to war with the US.
It is the US that is trying to go to war with Iran. This latest even is an act of war by the US, and is not based on any proven action by Iran.
That is true but Iran might decide to strike back US and that might even mean begininig of world war.
Anyway, any war activities might effect economy in Iran but I don't think that Bitcoin could play any role in that and the state will definetely not turn to Bitcoin, maybe only some individuals.
