As bitcoin has changed lives of people and frost world countries are getting huge benefits from bitcoin and surely in the same way bitcoin can give boost to the economy and bitcoin is the key way to the development and progress and i am sure that btc will boost economy as well due to its high prices and people can use bitcoin for their sake to generate income.
Not totally boost the economy instead its help by individual financial problem, let say this is you source of income for the whole week or month maybe but I think that's not enough for daily needs. Not for sure if this bitcoin boost the economy of countries.
