I do not see bitcoin helping the world economy but rather it can help an individual economy. Obviously, every country will not legalise bitcoin but the individual economy that adopts bitcoin can push in a huge investment when bitcoin is down to get some accruing profit from investment when price go up. By such profit, the individual country can better her nation and her people by providing more social amenities, building projects, factories and employment.
Very well said. It seems to me that bitcoin can help us, in many ways but in economy of every country not sure as what said above bitcoin is not legal in many countries still theres a country rejecting bitcoin and as an individual economy we should know the proper use of it so even though out world economy did not accept it yet at least it can help us in our financial necessity.
