Libra is popular because it is supported by the big company (Facebook). So the name is easily famous. Basically, Libra is the same as other ICO or IEO projects. Libra has just come up with a name, but all the media talk about it. This is not necessarily successful, because the Libra concept is currently not running. Still in a diary.
If the government had allowed it, Libra would have actually been a project that would really do very great in future, it has lots of hype and I think that the team is a very sound team members since they are actually the team member of Facebook also, but it is quite then unfortunate that the government is even having issue with Facebook Libra coin more that even their king of cryptocurrency (Bitcoin).
I have seen many government beginning to see how they can adopt and regulate bitcoin, but hearing of this Facebook Libra coin really provokes them a lot and I believe it is because of the challenge that Facebook has been having on lack of trust for its privacy which I think is the reason why they don’t want to give a chance to the Libra.
The target of Libra coins is to become a crypto-based world currency. Of course this is contrary to the concept of fiat currency. And will make the fiat currency lost function, so to get permission about the Libra project will be difficult to complete. And whether this target will be easily achieved. I think this is a difficult thing. Not something that is easy to replace conventional currency. What I understand about the Libra concept is as I explained, although the website is not clearly written on Libra's final target.
Back to the concept of Bitcoin. Bitcoin is only to facilitate transactions, and make a crypto-based currency without control of any party, including the developer. This target is clear, it has been running for 10 years, and we can feel it.
