Putting the amount at $10 billion might well put you into hat-eating
territory. You would probably be safe at $50 billion though.
There are 4 billion Web users. FB gets 10% of them on Libre, an average
float of $20 puts them at $8 billion. But that really isn't a lot of money
at Internet scale.
It is entirely possible that Libre becomes a reserve currency in its own
right but it won't happen overnight and if it does happen it will be simply
because it turns out to be convenient for international companies to use
for settlements reducing the currency risk on both sides. And if that did
happen it would likely be through some EFT like structure that is actually
separate from the exchange system.
I can see Libre becoming a $400 billion company in its own right because
that is what Visa corp is today. But it will take quite a while getting
What Libre won't do is to replace the dollar or euro or the like.
