There are so many problems that this world is facing. And i think bitcoin cannot solve it alone. World leaders should unite and make some move to solve world problems.
And how will Bitcoin end those problem? Bitcoin is just a digital currency that is invented by Satoshi Nakamoto for the people to make transactions efficient and experience its freedom.
As far as I know Satoshi Nakamoto did not make Bitcoin so it will be ending or solving the problem that is the world is experiencing right now.
