I think that many countries and their central banks will create their own digital currency. This will be done, firstly, in contrast to the decentralized crypto currency, in order to divert the attention of the population from it, and secondly, to use the opportunities and advantages of the crypto currency. Although it will already be a managed crypto currency, however, especially within the state, such a crypto currency can successfully go, because it will combine the digital possibilities of crypto currency and national money. Some countries already create such own types of crypto-currency, and even more express their intention to create it. In general, it will be good, as the population will be attracted to the crypto currency by the authority of the state and will be convinced of the advantages of decentralized crypto currency over centralized.
