Yes, Bitcoin has stood at $ 6000 this year and this is excellent, but I dont know it will rise higher in December, but I really hope so.
It depends the circulation of the bitcoin, but in my speculation if the bitcoin will rise this December I know this pattern.
Not every pattern has to be confirmed again. You should take into account what happened after the last bull run. Huge drops during the year will definitely cause that people will be much more cautious when investing money. Therefore, repeating the situation from the previous year is not so sure.
