The historical high for XRP was about $0.09 at the top of the market and before it was flooded by selling founders. Unlike Bitcoin there are billions of XRP in the system held by the founders and the administrators of the federated protocol, making the supply side units larger than Bitcoin in one sense, but comparable if you consider the divisibility of bits.
Similarly, Ethereum has billions of potential units that could enter the market, but a tighter supply release has kept the price higher, at a market top of about $21.00.
With that in mind, widening adoption, the eventual absorption of excess supply flooding the market and a boost in speculation as the system hardens point to some growth potential. Can it really go lower than .006, it’s current rate? There are a lot of reasons why Ripple does not enjoy the support of many influencers and miners in the crypto community, but their success with mainstream banks point to significant adoption. I would be surprised if the price didn’t recover back to .02 or .03, and potentially to go to .50 if consumer apps find a foothold. The key is to soak up the billions of units in the market on the sell side, then the price will rise.
Update: since this original answer Ethereum has topped out at over $400 and fallen back and Ripple has reached highs of around $0.35 – with the April/May vertical jump an indication of the end of the sell market flood. Hub Culture Syndicate guidance for these assets is now up to $2 for Ripple in the bank of growing bank integration and $55 for Ethereum which is low compared to the current price but more indicative of a total market cap in the billions vs. trillions, as currently reflected by out of line fundamentals.
