Target launch for Libra is in the first half of 2020. Libra will start as a permissioned blockchain (Bitcoin, Ethereum, Litecoin, etc are
permissionless blockchain). Meaning, you can't mine it if you are not allowed by the Libra Association to mine it.
You can apply to be a Founding Member to have rights to run a Validator Node. Only
1 billion dollars is needed to apply

.
I'll stick with the decentralized and permissionless coins
