Yes I certainly agree with your perspective that in the future bitcoin will be bright, besides that in the future I am also very sure if a country has not legalized bitcoin then in the future 80% country will definitely legalize bitcoin, because 20% of countries that have not legalized bitcoin may really you say that bank owners think that it will ruin their banking business.
bitcoin will be very useful in the community later because some needs that are now often done such as electronic transactions have begun much then it will not be much different in the future this will become more and more habits and bitcoin as electronic money will be needed later to become a tool of transactions.
