Considering that Facebook's Libra will be an extremely centralized cryptocurrency, it might very well be adopted by financial institutions within the mainstream world. Ripple's XRP also has the same purpose where it could drive mainstream payments in a fast and cheap way, backed by many Banks worldwide. While both Libra and XRP have their similarities (in terms of centralization) they're certainly different by design.
If Libra's launch becomes a success, then XRP's existence may be threatened over the long term. Both cryptocurrencies would battle head-to-head in order to become the top choice of Banks worldwide. Comparing Libra vs XRP, Ripple has all the possibilities of taking the lead because of the many partnerships it has established with Banks worldwide.
Which is why, it makes me wonder whenever Libra will become the currency of the world or XRP? Or will they co-exist in the future?

This is the same as the USD which is used as the world currency rate, but EUR still has a high value compared to USD.
