Indeed 2017 will introduce well thought out new use cases. I also believe this will influence the growth and the price of bitcoin.
MegaUpload 2.0 for example will help many people familiarize with bitcoin and is just the beginning.
I'm following closely the news regarding this, and other projects.
If developers deliver these applications, if at least some of these applications hit the market, we will see mainstream media coverage of Bitcoin, and probably a high increase in demand. From my point of view, these are good times to invest and hold Bitcoin.
