The future of Libra will depend on the coming political (first) and economical changes in the USA. I see Trump intends to support Facebook.
It could be, but you have to remember that EU is also being hard on Facebook and Mark. We all know that he has a meeting with European Parliament 2 years ago and it didn't turn out well. Plus I believed that it Biden won the next Presidential race, he will be a total anti-crypto, so I don't know how it will benefited Mark Z there. So I would say that there is no future. If they want to enter the picture again, they should have first study the accusations against them and then make a solutions.
