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.
Bitcoin will indeed not play a role as a substitute for their country's currency but bitcoin is played by individuals there to rescue their assets. When a war breaks out, access to their finances may be impossible, they try to save everything before something worse happens. Yeah this will lead opinion further from other countries as well, hopefully everything will be fine.
