But exchanges aren't being discussed in it...
^{- Btw, thank you for the translation part.}

I read everything and it appears that they only confiscated those mining rigs that were imported illegally + miners that were mining illegally with a workaround for using cheaper rates ^{[they deserve it]}.
^{- Having said that, I respectfully disagree with half of the things that the prosecutor mentioned in that article; If you contact Bitmain and ask if they've sent mining rigs to Iran [legally], the answer to that will be "Yes" [I'll post an update if I'm able to find the conversation that I had with one of their representatives a few years back] but I also know that not every single mining rig [ASIC] has been imported legally [due to corruption]. Another issue that I noticed was the fact that the prosecutor in question, generalized the process of mining cryptocurrencies and that means even GPU's shouldn't be allowed and that's not the case. All I can say is there are a lot of flaws in the current system and some of the imposed rules were made by people that don't know everything about both BTCitcoin and mining as a whole [SMH].}
