I have never been close on these predictions so I will just throw out a number (that will be wrong):
$25,000
It's really interesting as you always get into prediction thread and be able to maintain it every year when the time has come, refers to this thread:
https://bitcointalk.org/index.php?topic=1734516.0So funny when some people predict it precisely while kwukduck said $37

Back to the topic,
Why you choose $25,000?
Bitcoin price in South Korea ever reach over $24,000 few months ago, don't you think it will be easy to recover to this price?
Current price is $13,890 on preev and $13,965 on coinmarketcap. If wee look at the chart in last year, bitcoin could doubled its price ($2K) in May 2017 and increases significantly in October-December after financial institutions starts accepting bitcoin or at least listed bitcoin in trading futures.
The game changer in bitcoin are scale solution be implemented and acceptance such as in Japan and Belarus, after all things set in place, I guess bitcoin can reach $50,000 in January 1
