After last night's move up, the possibility of a triangle correction that would complete the cycle-level 4 emerges. If this chart plays out, buying the E could be the BTC trade of the year, since you would be buying the bottom of a cycle-level 5 impuluse which should easily take us to new highs before its completion.
The deep 73%+ retracement level is uncharacteristic of a 4 and of a triangle, but it is hard to deny it as a possibility given the geometry.
