I think the big year of bitcoin was when it went form a dollar to 1k usd but now it will slowly and steadily increase in real value as more and more people use it. I don't know if 2017 is going to be the year for bitcoin because it really depends on who has luck making and accumulating it I guess.
We can't really say something about that. No one can really say, actually.
So let's just hope everyday, every year, that something good may happen.
