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 am exciting with megaupload 2.0 launching next year, with their bitcoin bitcache feature. Also there are many news about bitcoin adoption even the government services.Indeed 2017 is an exciting growth for bitcoin.
Im thinking the same thing too on which bitcoin would surely have a good year on 2017, big adoption events will surely happen like you said about megaupload. Im waiting for that too on which we could say that adoption really booms out as the days and months goes by and we cant really stop it. Adoption is really the main thing that really affects the bitcoins price movement, the more people will use it the higher the price.
