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
That would be pretty nice and most people would want to spend that money on their Altcoins and pump that up too.
