Central bank 🏦 as a possible solution to a volatile crypto currency is a bad idea and the worse scenario that will happen to bitcoin. It will end its purpose and be controlled over by the financial elites and the government. We wont want that to happen.
Id rather have a volatile bitcoin in many years as it exist than give the opportunity for the greedy to manage and regulate it. It would be a game over move and Satoshi Nakamotos vision about anonymity will all go to waste.
