Some analysts are of the view that Bitcoin Price could reach a peak in December that is double the price now?
Dec. 2015 - $400+ level
Dec. 2016 - $700+ level up to closed to $1,000 level
Dec. 2017 - ATH at $17,000 level
Dec. 2018 -

No one knows what will happened so definitely, even how good the analyst is, still it's unpredictable. If you will believed on that, it's fine since you have lots of reasons to believed on that. But never take away the chances that it might not happened. You just have to wait until December to know what will be the price.
Trust the process.
Yes, everything is in prediction which we cannot underestimate the Bitcoin, this year many big investors predicted Bitcoin will reach more than $25k but how long this gone a take nobody doesn't know. The market situation is not accurate for many months which people cannot conclude what will be the price in December.
