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.
perhaps the case of Venezuela must be a very valuable lesson, considering that the politics that occur in the world is very influential on the value of a country's currency, to anticipate the bad things that can happen to one currency, perhaps the Bitcoin currency can be the best choice, because it can be used in many countries and security is very guaranteed, many countries that do not support bitcoin must immediately follow the steps of developed countries that have legalized the use of cripto as a legitimate medium of exchange.
