We can not run away from the fact that Bitcoin has a big influence on the world economy. Even though it is not officially recognized, the amount that is being traded is so huge that we cannot right it off. Imagine people exchanging bitcoin for fiat, don't you think this can influence other currencies? Just my thought
There is no doubt about this that bitcoin is influencing the world economy in different ways. Bitcoin is providing opportunities to people to earn money using different legal ways, we can say that bitcoin is increasing per capital income, which will certainly influence the economy of the world.
Although bitcoin is in its early stage, hope it will make the world more prosperous as time pass.
