Facebook's cryptocurrency program Libra will likely create multiple cryptocurrencies based on a single currency (such as US dollars) instead of the original plan based on a basket of currencies. Calibra CEO David Marcus said at a bank seminar on Sunday: "Libra's main goal remains to create a more efficient payment system, but is willing to consider other currency tokens. In addition to creating a stable currency based on a basket of currencies. Outside the currency, we can also create a series of stable coins, US dollar stable currency, Euro stable currency, Sterling stable currency, etc. We can create a more efficient payment system by creating a large number of stable coins representing the national currency. This should be considered One of the options. We care about the task, there are many ways to do this.” But Marcus also said that he is not suggesting that the stable currency linked to a single currency is a new priority for the project. Marcus also mentioned that Facebook is still planning to launch Libra in June 2020, but acknowledges that this may not be achieved due to regulatory barriers.
