It doesn't help the country's economy but it can support the citizen who wants to store their riches on BTC. If you take a look at Venezuela's situation, people are now interested in BTC because they now are trying to save their money before they'd be poor while having billions of cash on their vaults. Worse thing they might do right now is to create their own cryptocurrency which I think they were planing to.
I did not know of this at first, but your opinion has greatly increased my knowledge about bitcoins and a country with its citizens using it. Thank you very much!
