I think there will be a large number of BTCs sold at the end of the year, BTC holders will sell them massively, explaining this because they need cash for the new 2018 welcome.
I think it's quite the opposite. By the end of 2017, is when the bitcoin futures will be available. The price might keep going down until then, but the Wall Street guys will still get into it. I'm sure they are enjoying this crash now, because it only means that they will get bitcoin at a much better price. Everyone that is selling BTC out of emotions will soon regret it. I guess it will always be like this, whales will get richer because most people just get carried away with FUD and panic sells...
