Bitcoins have three useful qualities in a currency, according to The Economist in January 2015: they are "hard to earn, limited in supply and easy to verify". Economists define money as a store of value, a medium of exchange and a unit of account, and agree that bitcoin has some way to go to meet all these criteria.
A lot of people who doesn't know more about bitcoin will gonna say bitcoin will not help to improve the economy or it will make it worst because it is full of scam and fraud, but i think bitcoin is good for the economy because a lot of people would be given a chance to have a better income than their regular jobs that they could be a millionaire someday, if they continue to used and invest bitcoin in their daily lives.
