Thank you for your question!
After lifting the sanctions it couldn't be easier to invest in Iran. The barrier to reimpose the sanctions is high as long as the Western world is divided. Europe wants to make business in Iran and won't listen to the U.S. or KSA. The more business Europe makes in Iran the less likely are new sanctions.
Go for it!
Sounds very interesting. I wonder if they have a bitcoin community in Iran :)
well, doesn't matter as long as the business is paid... (-;
