Sure, end of the year is always a bit bearish for btc.

You got tons of people needing the money so willing to sell.
You got people taken back by the end of the year taxes.
Overall anyway you have all those people who invested after the major growth of black friday but didn't do it for any rationnal reason, just because price was getting higher.

It's no problem if btc goes to 10k. It would be good in fact. BTC was 8k 2 months ago, let us rejoice it has safely secured a 25% growth in less than a quarter! we shouldn't say price is going down, we should say price is stabilizing above a +25% fain from few months ago.
