Libra has raised fears about the future of blockchain mainly because it goes against everything the community wants and believes in: decentralization.
Facebook could ultimately create a massive closed-loop revenue model from ads, digital marketplace, to payments. Do consumers want to bet on the status quo of existing monoliths?
https://elixxir.io/blog/is-libra-the-future-anyone-wants If I'm not mistaken, Libra is the name of the blockchain, and Calibra is the name of the company. I see the Facebook team wants to build a Blockchain and coins that have coin capacity levels into global currencies. I think this is not much different from the blockchain that we are currently using. Maybe the Libra name is popular more quickly because it has a Facebook team. For the truth of this we have not found. Perhaps the strength of Libra is that it is easier to recruit investors compared to Bitcoin in the past. Bitcoin is formed from the ground up, whereas Libra has already been there Facebook as a strong foundation.
Well, in my opinion Libra has nothing difference to other altcoins that will rise here in crypto industry. Even some of the community thinking that Libra will surpass bitcoin, that won't be happen no matter how strong their big connection they have in business world. It will only be like what happened to other altcoins in the end.
