Yes. I am sure bitcoin changed people future and changed world.it can very easily .if bitcoin knowledge popular all country .so people earn bitcoin and it changed world.
Bitcoin change the way of living for everyone who knows it as it changes the world also. As the technology changes that fast that everything can be done through the network. Only the internet is not fast as the technology evolved because their are some places that still don't have internet.
What I see is,
Bitcoin has changed the economy of many people, especially the middle class and the poor. For the rich, they can invest anytime and whatever they want. They can invest easily, with large amounts and they will benefit a lot too. That's why
Bitcoin is so valuable to the poor ... because they have to follow the footsteps of the rich who always invest to double their money. The poor can not just save money, but they must learn to invest and know the true value of the investment. Because I'm sure, no rich people do not invest. Surely they all invest in their own way, not just
Bitcoin. And
Bitcoin, is the solution for the world's economy.
