I am no expert on the development aspect of the Libra itself, but just 
by looking at what we already know, I can say that Libra can easily 
exceed $10 Billion market cap. Just look at XRP, a company from ground 
zero, just because of the Blockchain technology, it attracted a lot of 
people and now has around $14 Billion market cap. Now if a company like 
Facebook, who is well known by almost everyone, comes up with such 
product, of course it will attract a lot of people and I am expecting a 
market cap over $100 Billion in couple years. Heck, it could even exceed 
that easily.

When you think about it, Facebook already has a built in marketplace 
script, all they have to do is to make Libra official currency there, 
and make some agreements with the banks around the world (mostly EU 
banks due to regulations in US), they can easily hold a powerful place 
in the finance industry. If people bought Ripple with almost no 
advertising, many people will buy Libra too. And if Ripple could be used 
by banks (I am from Turkey and even we have a bank that allows you to 
send GBP to some banks in UK via Ripple network. Literally I can login 
to their online bank and see the name "Ripple" under transfer options) 
so can Libra.

As for the scalability, I don't know much about the technology they are 
going to use, but it doesn't have to be a public blockchain application. 
And if Facebook's/Instagram's servers can handle the content traffic, 
then they can easily handle the transactions, and all they have to do 
could be wrap up all the transactions in any given minute and record it 
to the blockchain. We don't know if they are going to make it a 
distributed blockchain or not. So maybe, they can just use the 
technology's name, keep the records in chain, and do all the other stuff 
in regular servers. And if they really want a blockchain app, I am 
pretty sure they can handle 30K+ transactions per second.

And for the idea of it, it doesn't have to replace the USD or any other 
currency in one day, but it sure will be around in the future.
