Bitcoin can actually impact positively on the economy of a country and this may not have to be that we should expect seing the impact within a short period of time, it takes time for us to acheive what we want with bitcoin adoption, not that we can't realize any tangible influence from its adoption, but some things have to be in place as well as the time frame required for it manifestation, maybe when we begin to have countries adopting bitcoin as a legal tender like the way El-Salvador and Central African Republic did, things may be more obvious about the impact of bitcoin on each country's economy.
