as i suspected bitcoin price is not ready for $1000 yet. and it is not ready to go down either as we can see a good resistance is forming up to keep bitcoin price in $700+ range.
so to answer your question, although bitcoin is always unpredictable but you have to think at least mid 2017 for any price around $1000
I agree with this timeline, but only if there are no big hacks of relevant bitcoin exchanges and not to much further regulation from the european union and the us goverment.
