Possible bottom, last trend line starting 2017-11-12 hitting chandle min 2017-12-22 may contain negative pressure on BTC, weekly and monthly chart show a clear positive trend. For this reason selling pressure is decreasing and up trend could start again, next obstacle is negative blue trendline descending from top. RSI indicator may bottoming and sthocastic oscillator too, it seems a bear trap, In my opinion upper trend is intact. As soon as the price overtake the descending blue trendline the price will fly again.
