There's even a thread for that here in economic section: Iran accepting cryptocurrencies to avoid US Dollar - https://bitcointalk.org/index.php?topic=5285438.0
Well they are trying to avoid sanctions, and probably it will be easier for their supporters to send them crypto than to go through the banks with any fiat currency! Big players have their own ways of doing business, we know who are stronger players on the global stage and who are the weaker ones, and they play games for centuries! I don't believe in all the stories, and most of the stories about them are just conspiracy theories, its one of the ways how they keep people apart... I don't bother too much with them anymore, I think crypto can change all that for better and I hope that it will come sooner that most of us expect!
