I wonder if there is a way to take advantage of this fact. For example, the first thing that comes to mind is arbitrage trading. If you know someone in Iran and if you can move money across the border, probably you can. The other question is if this is just a temporary spike.
Yes it could be done but seems it will be really hard cause of the embargo by the US. I dont think you could even move a dollar into iran and seems like US will think another way to block transaction from iran evem though they using bitcoin or any other crypto to make outside transactions.
