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.
Bitcoin can change the lives of a individual person as long as he/she is having perseverance in investing/trading btc. But i'm not sure if btc will boost the regional economy. It can be possible but it will becomes so hard. Because everyone does not have the skills in making business decisions and plans in connection to BTC.
