I'm not much of an Elliott Wave fanboy these days but it is interesting that having broken out BTC .D appears to be in a fairly classic Elliott Wave even with alternation - deep wave 2 and flat wave 4 albeit with a rogue 3 wave pattern within the third wave.
A 1:1 target taken from pivots 2,3,4 would see BTC .D wave 5 extend up to around 48%, maybe slightly more with overshoot, which interestingly is where there have been many tops already.
Perhaps after that peak is where the real alt season begins, though to be fair plenty of alts going bananas already.
