." ♪ carol: we are here with the editor in chief of "bloomberg businessweek," joel webber. lot of good stories this week. joel: i try. carol: and you succeed. i want to start with finance, first of all, the digital currency world. while we spend time talking about bitcoin, there's another currency that you guys have been looking into. joel: part of this is, the crypto boom and maybe the receding of said boom that has created a lot of confusion. right? it seems like bitcoin is a hot thing, and then ethereum and ether. where are my supposed to get into this? there is another that has caused a lot of attention recently, called ripple. so we wanted to take a hard look at ripple. one of the things we did is, in talking to the banking community -- because ripple says it is a banking solution. we talked to the banking community said, we don't know what this is for. carol: not so much? joel: xrp, the digital currency affiliated with ripple, the thing is sort of like, what is this going to be for? even though there is a lot of enthusiasm, there's still reason to be really skeptical.
