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.
Actually ,it just easy to earn bitcoin if you have money to buy it. And if you have money try to join campaign that promoting different projects and pay you with their tokens then exchange it to bitcoin. Very easy. Bitcoin is good for economy if it will just mix to a fiat money because they have different value and features. You know government is very allergic in Decentralized currency ,so it's difficult for them to accept bitcoin as part of the economy.
