Of a truth as a trader i have never think of bitcoin fall to this value we are now as at November and December 2017 but bitcoin is currently below $8,000. I foreseeing that what has been started is truth and in reality bitcoin should not be expected to be below $10,000 by next year and above. I expect bitcoin should be above $50,000 by 2019 and this year 2018 it should be above $20,000 before December.
Your speculation concern the current market to be like last November/December is correct but for bitcoin to go above 50,000 is not possible and if such thing happen that will make bitcoin a bubble. However, there's no market pumping force which will push the bitcoin market to the price range you mention.
For me its hard to know the price of bitcoin and we dont know if what day or year to growth the price of bitcoin because its depends of supply or demand of people so if you planning to buy or sell wait the perfect timing.
