I believe Yes! This coin will be a game changer. As it is backed up a few big companies like PP, Master card and Coinbase etc. Also, more than 2.2 Billion people who are using Social media will be using it, It surely going to take down bitcoin.
I believe No! Because the Whitepaper of Libra presents that fact that the coin will destroy core idea of crypto currencies, and it is too far away from decentralization. We don't need centralized crypto currencies. Someone can launch such coins, like Libra, and those coins might survive, grow well, and accepted, but to replace bitcoin, and other powerful, widely accepted decentralized crypto currencies. I would say No! Crypto Newbies will easily accept Libra, but they will sooner or later realize their mistakes by using a centralized coin. Facebook, itself is a centralized social media platform. Together, using Facebook and Libra put users under high risks of ID leaks.
