This is only a prediction and nothing is certain. This is just the announcement from 3 people involved in the development of Libra and there is no official information. In addition, a FINMA spokesperson declined to comment by Cointelegraph on the potential launch of Libra in January 2021, they are still in the process of resolving Libra's proceedings.
So we need to wait a few more weeks for official information. I think the information from FINMA will be more certain than the Cointelegraph.
