Honestly i believe Libra is supposed to bring a new huge changes to the world of international transactions but who can predict what will happen about Libra? Because Bitcoin is still the mother of all cryptocurrencies and Libra still relies on fiat currencies as underlying assets. Bitcoin is decentralized and other crypto assets with their own use cases and purposes will likely keep existing side by side of bitcoin.
If libra will be released (after lots of hurdles it is facing right now), it will help many people knowing about cryptos which will eventually end up in adopting bitcoins. Yes, people will compare and choose the most robust thing. In near future, this crypto space may find huge leap when facebook kind of market giants enter here. Libra will help people to invest into cryptos hassle free.
Already cryptos are marching unstoppable as most governments are still neutral on this and their federal banks are like to adopt it or at least then have started studying the importance of blockchain technology. Crypto is the future for sure and those who adopt cryptos at its early stage may find themselves blessed over the time.
