When will the Ripple (XRP) wave crest?

Despite altcoins being very much off-trend at the moment, XRP, the payment coin developed by US technology group Ripple Labs, has been riding a wave of popular sentiment. The coin hit a 10-month high of US$0.585 on Wednesday and though there has been some retraction since then, that does not remove the fact that XRP has rallied over 50% in March alone.
