By the way the news was the opposite meaning you can't spend bitcoins mined inside Iran for anything other than import/export.
Wrong.
Here is the article reporting that any bitcoin mined abroad is not allowed to be used in Iran for anything including trading, and they are actually selling most of the coins mined in Iran to avoid restrictions related to sanctions.
Iran also banned usage of Bitcoin for payment, they are seizing ''illicit'' Bitcoin mining machines all the time, and they banned mining during summer time.

If you read in the link Persian that the article included in first paragraph it doesn't even mention anything about a "ban". Actually here is a better
link.
There are 2 things here.
1. The central bank (which has nothing to do with the "law" and "bans") is warning people to be careful when it comes to cryptocurrencies due to their volatile nature and also not to get scammed.
2. It is saying that the government, banks, etc. can only use bitcoin's mined inside country for imports which is to prevent the government for example using a foreign exchange to swap USD for BTC then use BTC for import which would make no sense. It has no restrictions on what people do.
And again the Parliament (Majles) has to pass the law. Central bank or even the government making statements don't make them into "law".
