According to CoinDesk, Katherine Wu, a former member of the US Securities and Exchange Commission (SEC) and the administrator of NotificCapital, a blockchain investment fund, said that 2020 should pay attention to the central bank's digital currency. She explained that all Chinese technology companies are developing blockchain solutions; all payment platforms have unhindered access to central bank digital currencies. This means that when the central bank's digital currency comes out, it can be used immediately, and large technology companies can use the central bank's digital currency to develop blockchain business. Katherine said, "I can imagine that in 2020, the central bank's digital currency will be the only digital currency supported by a large country. Users can use this digital currency to buy anything, not as many restrictions as Libra.
