2 more coincidences
-Once crossing the previous ATH until reaching the new one, 36 and 39 weeks have passed in both cicles.
2.-There is a symmetry from the minimum to the maximum of each cycle. There is approx. the same distance from the minimum to the halving, than from the halving to the next ATH.
So with all this, we wouldn't see a new ATh till 2021, probably between feb and jul 2021
