Ripple isn't coupled with the BTC price. For other altcoins you can only buy them with BTC so if Bitcoin goes up, so does the dollar value of most altcoins. For Ripple this is not the case as you can also buy them with other currencies. This makes them more resistant to Bitcoin dips sometimes, but also means they don't benefit from Bitcoin gains as much, if at all.

I don't see Ripple making any big moves anytime soon. Then again, I don't see it dropping too much from here either, maybe at most 5-10%. I don't think it's going to jump significantly unless major news is released. You have to keep in mind, Ripple already has a large market cap. If I were investing purely for monetary gain today, I think there are bets to make that pay out more, in a shorter time frame. This is likely why the traders are in other markets, because they probably think similarly.
