I think it can because the bitcoin can become a way for them to transact and transfer huge payments which fast speed of transaction and also a cheap fee for their transaction so it will give a huge discount and a way to save money for the country and also for the other people that will use it and those saved money will result to have a better economy of the country because they can use the saved money to make profitable investment or businesses.
Bitcoin will make the way for itself because the bitcoin will be very high and a lot of the countries are investing the bitcoin and they are supporting it, for me it is the point and the investing power that will decide that how much bitcoin you will invest and how much bitcoin you will save for the long time, now the bitcoin is getting famous and the bitcoin is easy to earn by investing the small in the bitcoin.
Easy? No, I do not think it is easy to earn Bitcoin with investment. It can be good for those who have knowledge, experience and good traders. But for newbie, I do not think them can earn good profits through trading easily as your said. They will need to spend something to receive the experience and become the professional traders. That is their journey.
