Bitcoin is still bullish. Update.December 24, 2018
Still on the bull side, but the formation of the extreme weekly candle looks alarming. If the shadow remains more than the body, then it is very likely that we will further get a step down. This does not cancel the scenario of moving to the range of 4500-4960, a corrective pullback is quite a healthy phenomenon and a possible step down is exactly what it is (relative to the last growth wave).
