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.
Yep, just like end of 2013 was bearish

BTW end of 2016 was nothing but bearish, it finished within $50 of the all-year high on the last trading day, so its not a pattern at all.
