The value of Ripple heavily relies on the usage of its networks by banks. The more banks that join, the higher the value gets.
Similar to how Siacoin's value would increase if a large firm were to use its network for cloud storage.
Hard to put a number on that, but with ripple's high supply it might be hard to hit 10k.
Coin supply is the big issue here. Go look at coin market cap and see how much of a market cap Ripple would have to have to hit $10,000. It's just not going to happen anytime soon. Would require A LOT more money coming into the crypto world.
