Interesting
So this is a non-story so far (even with the backstory of Iran doing bitcoin mining - there are pros and cons of using it, though of course it is the most likely answer)
To pay with crypto you first need to acquire it (multiple ways to do it - including not so legal ones, though I'm not saying which way might have been)
So there is that.
But the story ultimately looks entirely based on a tweet [1] from an official that Google translates as:
> This week, the first official import order registration with #currency_currency worth 10 million dollars was successfully completed. By the end of September, the use of cryptocurrencies and smart contracts will be widespread in foreign trade with target countries.
So I agree that the story is pretty thin.
