People need to realize that bitcoin will not fix a whole country by itself. The citizens need to have that initiative to buy and hold/trade bitcoin for the betterment of their lives. The government needs to be pro-bitcoin so it can actually help a country get better economically speaking.
But if you want to take advantage of the difference between usd and say any fiat money from any country, then that would be a totally different story.
Hmmmm.. you are right that Bitcoin can not fix country economic problems on its own. People need to take action and use Bitcoin to improve their financial situation. Government also needs to support Bitcoin to help country economy grow. But if someone wants to make money by exchanging USD for other currencies that is different approach. Overall Bitcoin can help country economy if people use it and government allows it to grow but it ca not do it alone.
