In 2008, there was a huge economic catastrophe in the world. Some banks conspired and deliberately caused this economic disaster. This is why many people were financially disadvantaged and lost their trust in the bank. I think Satoshi made bitcoin to save people from this disaster. That is, Satoshi has created a currency where there is no third party. There will be no central bank. No one can control it. Customer to customer transactions can be done. While Bitcoin has no controller, no one will be able to intentionally disrupt its finances. Bitcoin introduced a new horizon to the world's economy and freed people from this economic catastrophe.
So I think this is why Bitcoin was created. Is that the only reason? Or are there more reasons? What is your opinion?
Bitcoin did not and will not save the world from economic disaster. The number of cryptocurrency users at the moment is too small to globally affect the situation. At the same time, since the creation of Bitcoin, the correct vector of development has been set, which will change the world in the future.
