I think you totally have no idea what you are saying and how cryptocurrency work, we cannot do anything to stop or prevent new cryptocurrency from coming out every single day. People can make their own without revealing their true identity and it doesn't require to be registered or even licensed to create a new one so how can we stop a new decentralized cryptocurrency to come out? this is the bad side of cryptocurrency specially Bitcoin being an open source, people can just copy and edit the codes and run it without any difficulties, and we cannot do anything about this anymore.
