I can't be sure if libra coin will success to be launched on this year since there are a lot problems that must be headed by facebook. Such as government, you can see how decision that has gave by US government it will be the big defiance for them other than that some of their partner has leaved them slowly. Indeed, they overcome all social media and it will be easy for them to promote the project and many people will use it without any hasitation. But their problem can't be easy to face even I got some news if they force to launch libra coin then facebook must pay a high tax to US government.
