In my opinion, Bitcoin is the first decentralized digital currency, and it is a kind of payment in different aspects of business. According to the bitcoin experts here bitcoin also was invented by the group of programmers under the name of Satoshi Nakamoto. Correct me if I'm wrong.
no satoshi was one person. but satoshi didnt work alone.
only one person used the satoshi pseudonym. but that does not mean that he wrote every line of code and invented all the concepts that built bitcoin
it was a patchwork of many concepts from many people. but satoshi as one person pieced it together. he then got other people like hal finney, sirius etc to help him refine it. but hal and sirius and others did not use the satoshi pseudonym
