In my opinion, the price of bitcoin seems difficult to reach $100k in December because after experiencing a decline in the price of the last few weeks, the price of bitcoin is still not showing a significant increase. Therefore, maybe in December the price of bitcoin will only reach $70k especially now that it has entered the end of 2021.
to reach $70k by the end of the year there seems to be hope, although it is very difficult to happen.
today the price of bitcoin fell back below $50k and I hope that $50k is no longer a resistance line that is difficult for bitcoin to break. if this happens again of course the price of bitcoin will be stuck below $50k for quite a long time and the chance to reach $70k by the end of the year is getting smaller.
