I agree with people who say that there is no need of a central bank for cryptocurrency markets because people like it and invest in it as it is decentralized. Central bank gives ownership to a particular bank and it will increase documentation process. Few people want to be anonymous in crypto world and few countries also may not like this concept.
For me, the beauty of cryptocurrency is that people are not included in the process of performing key actions. Because in the world there is no person who wouldn't want to have something to fuck with what dominates.
