Brad Garlinghouse
Everyone knows a friend of a friend who's made a fortune thanks to the recent rise of cryptocurrency, but no one knows anyone who's doing quite as well as Brad Garlinghouse. As the CEO of Ripple, a money transfer network and digital asset (XRP), the Harvard M.B.A. is worth an estimated $400-$500 million - and that's thanks to his personal stash of XRP. Forget Bitcoin. Ripple is set to be the top cryptocurrency of 2018, and that makes Brad a big name to know. (Hi, Brad. Are you single?)
