I approach XRP long term, because:

• The token is designed to be utterly stable in price, rather than a speculative asset
• Banks like the settlement technology but are (still) reluctant to use XRP to facilitate money transfers
• Banks interested in buying XRP are not doing it on exchanges but directly from Ripple

Therefore my assumption is that any eventual significant rise in the value of XRP, unless out of pure speculation, will most likely not be exponential (as Ripple wants it to be stable) and will probably not happen any time soon (until banks feel comfortable to actually start settling XRP).
