Here at Main Bloq we like to keep track of the process by which cryptocurrency news seeps into pop culture. Here’s a new instance: a very high profile donation using Ripple (xrp).

Ashton Kutcher is best known as an actor. He starred in Dude, Where’s My Car?, The Butterfly Effect, and Jobs.

He is also a very savvy investor, having gotten early into Skype, Foursquare, Airbnb, etc.

He recently made a drop-in appearance on Ellen DeGeneres’ talk show. He talked up Ripple, and  segued into a discussion of a cause to which DeGeneres is devoted, African wildlife preservation.  For the benefit of that cause, he used a ripple app to transfer to her US$4 million, exchanged into Rwandan francs and deposited into a Wildlife Fund.
