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.
Is it good to economy? For me it really is 
. In my perspective, since I can be able to uplift my financial status through the help of it then it only means that I am not a burden in our society. Since I'm not a burden thus I maybe considered as productive and healty part of our country; and if there will be many existing individuals who got the same story like me then it definitely means a good economy 
(I hope you got my point tho). That's why I really wonder why some government (not ours, fortunately) really hate crypto. How sad that they just see the bad side and disregarding the bright side
.
