I have adjusted my count for BTCUSD.
I now believe with the rising wedge pattern, and the projected length of wave 5 equal to wave 1, that the top of this 5 wave impulse has nearly been reached.
I anticipate that the blue support line that has been resistance for so long will hold for the correction, putting this larger wave 2 retracement in the area of the previous impulse wave 4 correction, and I am guessing that the form of the correction will be a downward triangle as BTCUSD has already demonstrated its propensity towards them.
