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.
How come that has some way to go in order to meet all of those criteria? I believe that began is already hard to earn and has only a limited in supply of the market also it is hard to verify so the last criteria is only the one that is having a hard time for the bitcoin in order to beyond currency all over the world. If the economy is define money as a store of value then bitcoin is also a store value in which you need to store bitcoin in some wallet or exchangers to have a amount of it otherwise bitcoin is really good for the economy because there is already some countries that are accepting bitcoin and they are all having a good economy and their economic growth is increasing.
