Earlier this week ShapeShift.io CEO Erik Vorhees announced that the firm would be shuttering its Prism investment platform. The platform was created to allow investors to create Ethereum ($ETH) based portfolios with multiple cryptoassets without holding assets on an exchange. The project was in closed-beta since its inception and was scheduled to go into open-beta later this month. Just last week ShapeShift announced that they will be switching to a mandatory membership model that will require users to register with their personal information.
