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.
BitShares do have its products and no need to rely on "Bitcoin denominated services", however there are too few commercial use cases atm, and right, not yet profitable. But bitcoin is profitable?
Lets just say that Bitcoin is not going broke any time soon. It certainly seems capable of gracefully absorbing 1.6 million dollars of daily inflation.
2.0 projects just need more useful apps, really. Fighting with bitcoin about who can provide bitcoin's services better has proven to be pretty much fruitless. The market doesn't care very much. If you want to move money into crypto from fiat, you use bitcoin; if you want to speculate on other digital currencies, you trade against Bitcoin; if you want to transfer large sums of money without going through banks, you do it with bitcoin; if you want to buy stuff online with e-currency, you do it with bitcoin.
Bitcoin was brilliantly engineered to be successful, and even the things that are questionable about it's implementation, play well with the human psyche and are probably intentional. eg the ridiculous expenditure on security.. really a way to create grass-roots marketing and encourage participation; the slow confirmation times.... really a way to add weight to the idea that an immutable transaction has occurred; the fact that creator of the protocol has 1.1Million coins that have not been spent... really a way to say I'm in this to win it.
2.0 projects need more infrastructure built on them, they need to provide different value than bitcoin provides. That value might not be new implementations of bitcoin's services, but the extension of those services. I think the hang-up has been that everybody is trying to create solutions that are completely decentralized... in the end, it's not possible for every single app to be decentralized. There will have to be actors and trust and reputation and single points of failure sometimes if there is to be an economy built on 2.0 platforms. That's the key to sustainable market cap, imo, bit Businesses.
