There're many discussions and analytics about Ripple, XRP. Almost their opinions are Ripple's partners only use xCurrent, not xRapid, it mean that XRP is not used. Beside that, they hate XRP because it's used in a blockchain which is not really decentralized.

However, I see Ripple have been getting more partnerships and there're new partners are ready for experiments on xRapid. That's a good signal for XRP. Keep tracking Ripple and see how they make XRP growing in 2018
