Fan Yifei, deputy governor of the People's Bank of China, said that digital currency issuers can be divided into private digital currencies and central bank digital currencies. Typical representatives of private digital currencies are currencies such as Bitcoin, as well as various so-called "stable currencies."
Private digital currencies have no national endorsement, and central bank digital currencies have the state as a credit guarantee.
If Bitcoin is a private digital currency. Then, the issuer is personal. Is this person Satoshi Nakamoto? Is he the owner of Bitcoin? However, Bitcoin is "decentralized." There is no issuer.
edit:In order to get a better understanding of my topic, I edited it a bit more deeply, thank you.
People tend to call it a store of value lately instead. It acts as a currency too but sometimes it is more practical to use a credit card instead because of its speed.
We currently do not know who created bitcoin. It is somebody who calls himself satoshi but this might be one person or a group. Nobody knows.
