When crypto 2.0 projects start delivering actual value, we will start seeing more stable prices. Nobody in crypto 2 space is really delivering any substantial value as of yet. Bitcoin has infrastructure, recognition, legal acknowledgement, provides a "fairly stable" store of value, and is the de-facto reserve currency of virtual business. Hence is has been more stable, because it is providing entities with more reasons to have some lying around than just to speculate with.
But what can you really do with these 2.0 platforms? What can one do with some Ether, with a Bit-share, with some Factom? Most of the stuff you can do, you are relying on Bitcoin denominated services to achieve, hence most of the people involved in the markets for these things are just speculating. There is little reason to hold these tokens atm, because the services that they proxy are not yet profitable.
