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.
This doesnt look like temporary hike in the Iran be sure the prices are like more than 4x the prices of international market and thus making me think how is that even possible. Arbitrage trading may be possible with the sites like localbitcoins becaus they do offer us international trades. The only concerning thing that left us out of this trade is whether Iranian is able to send us money over the borders or not. That will need huge trust and then only it can work.
