Looking at the BTC/USD chart on a 2-3 months scale we can see consolidation in a bearish wedge / sym, triangle formation within 2 major trend lines. I expect this formation to finally break out to the lows (bearish continuation pattern). The local Maxima / Minima within the formation are timely spaced approximately within 1 month intervals.
So I expect the next local maximum to appear around 24th of January. Price height around 4000 USD.
Then maybe price decrease in Feb. to 1500-2500 USD/BTC, what many speculate...
Cross fingers, cheers
