We all knows that bitcoin is money or we can also called internet money and we can use bitcoin in any transaction that needs money because bitcoin is acceptable around the world but beyond this things I have a question.  My question is if satoshi Nakamoto is the creator of bitcoin, do you think what is the main reason why he need to create bitcoin because in terms of money all country has their own money that are acceptable as a representation of a thing in this world?

Anyone can give a comments?
