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.
As long as they can cope with electricity consumption and compared to the profits that can be obtained, I don't think this is a problem. but what if they can stand with it ?
