lets see what will happened to the market before this year runs out, or could anyone possible guess what will happen in December 2018.
I doubt anyone can give you answers to that. We're all in the dark here; people have different speculations in prices. I, however believe that bitcoin will be bullish in the last few months this year. This has always been the case in the previous year. Though we might not see a new ath then.
also will there be any upgrade in the bitcointalk forum?
The forum is fine as it is. Not very hospitable to newbies due to various restrictions but overall a good source of information.
