Ripple does seem to be slowing down.  Tron which is silly is still shooting up, huge supply, like 25 cents now.  Made a little off playing with that a couple days ago.

But, overall it seems these altcoins get pumped by a limited group, and then a still limited number of people are willing to risk investment in them, thus their incoming funds is starting to top out.  And without that their growth slows, a little profits get taken, noobies start to worry, etc.  I wouldn't be surprise if Ripple starts to drop now, move into another alt perhaps, or just back to BTC (and fiat since those markets exist).  We'll see if others want to then go back into other alts or just like many, start going back into a more dependable 9 year old Bitcoin...
