If we apply a bullish Elliot wave analysis to the preceding big swings in BTC, we can clearly define what could have been the five legs to complete a full advance. With the topping head and shoulders pattern being a final wave 5 and the drop we've had off there only being the first ("A") section of the correction.
If we're in an ABC pattern, we'd be high in B and set to head into a really harsh sell-off to break the previous lows.
