I don't have any idea what will happen in 2017 but with the recent dump of bitcoin the price is not stable anymore, but there are some signs that the bitcoin price is going to rise again but slowly this time.

The only thing we can do is to wait and watch as we cannot be sure what will be the exact scenario in next year, and no one can predict the exact price of bitcoin for sure.
True indeed we can not accurately predict the price because prices are always fluctuating. But I'm sure the price will increase because it is caused by the adoption in 2017 will continue to increase so that more people who know and use bitcoin.
