How many other cryptos did they do a Poc with? Ignoring BoE, Ripple's customers that are using XRP in production are: Moneygram, Cuallix, Mercury FX, and IDT.

How many other cryptos did they do a Poc with? Ignoring BoE, Ripple's customers that are using XRP in production are: Moneygram, Cuallix, Mercury FX, and IDT. There are also 100 customers using xCurrent (the pre-XRP product that's used to transfer fiat). Upgrading to xRapid would increase the speed and decrease the costs of such transfer, so I imagine there will a conversion of some of those 100 customers to using xRapid, and thus, XRP.
