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?
Well one thing about bitcoin is that it was meant for the people. Whether satoshi's real or not, i think the creators wanted to have an alternative to the current banking system where everything can be controlled and manipulized but people in the higher ups. Bitcoin removes that. Though the more bitcoin's value rises, the more it strays away from it's original uses.
Maybe because they want to make life easier with a digital money to use in everyday lives by paying btc in transactions. Bitcoin can potentially evolve and develop a country's economy because of its capability of becoming a country's currency. It is also a possible alternative to fiat so that you can have a safer bank although its price is volatile but can be preserved and wait for a higher price.
