libra is a stable coin like USDT, the idea of libra might want to rule the world in terms of payment I think libra will compete with us dollar. but in recent months the news of Libra has gotten worse and many of their partners left Libra because many countries do not support the presence of Libra.
I think that Facebook actually went out of boundary by trying to create a project that will be used as global currency when they know that the coin will be centralized and can easily be influenced unlike bitcoin that is decentralized and cannot be influenced by anyone. This is exactly one of the disadvantages of decentralization that we are seeing here now.
The best that Facebook would have actually done is just to limit the usage of their coin to Facebook advertisement platform where their business clients can just purchase the coin to make payment for their ad when it is about to start or ended, this project would have been very successful if they had done that, but with this global idea, countries will definitely not accept it because they will not want to leave the affairs of their country into the hands of an external factor.
