On the contrary I don't believe we will be having another December bull run this year. If we are expecting any bull run then we will have to wait till 2019 at least. Although it won't be far-fetched to say bitcoin can reach $8000+ levels this December because it has been sitting comfortably at $6000+ support level for several weeks now
Anything can happen here in crypto space since it is unpredictable and the probability again to have a December bull run is highly possible. It's just a matter of time and if people will keep on holding and not to panic selling, surely it will occur and we ca be gain enough profits.
