In my Opinion, I'm not sure can bitcoin change the bitcoin world because there are few country already ban the bitcoin, and also there some place that doesn't have an internet connection. Some of people don't know the benefits of it. Only I can say that I believe that bitcoin can change the way of lifestyle because of Bitcoin we can earn fiat. Bitcoin help to decrease the jobless in some country.
The value of Bitcoin fixed by the human, by the cryptocurrency community and they are also the investor, of course, Bitcoin can helps they have some jobs to work like me, but for the long time work, I think blockchain technology will be better than Bitcoin. A currency and a technology and solve all problems about the trust of the world.
