I think it's because people were hedging their bets that it might be BIG like PayPal or Amazon, they just decided to cut losses when it wasn't a 7.5 richter magnitude quake of significance in the cryptosphere. Daily buying and selling rather than people invested ideologically in the project or for the long-run. Such is the cryptosphere! Seems like it might lead to that level of partnership though if it's a success on PornHub.
