When? and Growing Utility?
Bitcoin has decreasing utility since the initial hype.
1. The few companies that accepted it are gradually stoping to support it (Microsoft for instance).
2. We have reached a standstill that shows every bit why highly unregulated systems are difficult to maintain (the miners care only about short term profit and are making bitcoin as a payment system unusable in order to secure short term profit).
3. Even great contributors for the project have come out against it lately explaining the total dystopian mess that is the bitcoin core team and exiting the project.[http://uk.businessinsider.com/bitcoin-has-failed-says-develo...]
4. Bitcoins are in the hand of a very few people that own massive amounts of them (see blockchain.info top wallets) that seem to be going around trying their best to get a few remaining uninformed people to believe in the system long enough so that they can offload their bitcoins.

I see very few people trying to get into bitcoin and a see a great deal of somewhat high profile people trying to keep the hype going just a bit more so that they can recover at least part of their investment in a failed experiment.
Still, 2 good things came out of this in the end: the blockchain which is a great tool for a lot of projects; and an eye opener of what can happen for people that want the financial system to have even less regulation.
