XRP is up 1000% in the last month. The market capitalization of the centralized bank based coin is now over $121 billion. Is XRP really worth the price? There has been much concern from the cryptocurrency space in the past few days about new investors getting burned.

CoinDesk reports the majority of Ripple's banking clients are using the company's xCurrent product – "a glorified messaging platform" and not XRP.

The question is do most of the new investors to Ripple and the Cryptocurrency space know this?
