I think it is doing pretty good.It is moving at fast pace and is trying best to replace paper currency.But still i would say transation cost in case of BTC is much more as compare to other visa cards and master cards.So BTC need much more to improve.Moveover BTC is still not accepted by many countries.So a lot more things are needed to be done ,so in coming years it can be expected.
I think it is good for those country who does not accept bitcoin to learn from the country that adapted bitcoin and how it helps for the improvement of the economy. They should not always see the bad side of it but also the good impact of it to the small people who wants a job and good earning. They could accept bitcoin when they realize how good it is.
