Speculation is all n good but don't take any random forum users saying as a financial advice since there's no doubt nobody knows for sure. Sure it might jump tomorrow to 20k or drop down to 4k, it all depends on the news and what's going on behind closed doors where the big boys discuss. I do not know whether BTC will jump in december and don't really even care, what i do know that it'll happen eventually and currently it's just a race against the clock who can accumulate the most before that timer runs out.
