I will say same as most of the people already said that in this December we will not see over 500 $ even there is still one week which is much to see any new high for this year.I think we will see between 450-470 $ over all in this year.
I still do not understand why posters are comfortable to predict BTC price points by using absolutes.
We should realize that there are no guarantees in bitcoin, and predicting in such ways is very imprecise concerning what is going to occur within about the next week.
More accurate is to view probabilities.
for example, at the moment, there is not much time left in the year, accordingly, I would predict as follows (Bitstamp) BTC prices:
During the remainder of December 2015, there is a
100% chance that we will experience greater than $455 BTC prices
85% chance that we will experience greater than $460 BTC prices
70% chance that we will experience greater than $470 BTC prices
60% chance that we will experience greater than $480 BTC prices
55% chance that we will experience greater than $490 BTC prices
51% chance that we will experience greater than $500 BTC prices
Even though I currently believe that the odds are favorable to reaching greater than $500, I am not going to phrase such prediction as an absolute.
