It was btc_angela said that the selling pressure do affect the market. The more people starting to have their sell positions it would've impact the current prices like we saw from last time. By the way, how did you end up with that stats? you conducted a dry run on your own with those emails?
Not only November, also December was a tough month. Even thought we saw a pull back from 3200 to 4400$ but this is looking temporary. The currecnt price is again under 3900$ and this level is very important for bitcoin to maintain.
I want to stop looking at the daily charts but it gives me more chills like last Sunday when I saw the market goes up a bit. I sold few by that time for the preparation this Christmas and will start to pack and collect again.
