It's highly unlikely for Iran to be the new "crypto mining paradise".Iran was never really bitcoin-friendly,due to the project of creating it's own cryptocurrency or due to the authoritarian nature of it's government.It's well known that authoritarian countries aren't crypto-friendly.
However,I'm surprised by the amount of mining hardware,that is currently used in Iran.
Well their electricity is virtually free isnt it? Or the government subsidizes it to some extent so to offer it very cheaply to its iranian citizens.
