ΣL Cycle Summary
Here we return to look at the excellent ~ 30 day cycle in Bitcoin, a smaller, less powerful but no less stationary brother of the 80 day cycle we have covered many times on the site. It is another interesting period because these two features are out of phase at the troughing zone of the larger feature. In the past, interactions between these two will result in general sideways price action as the two fight for dominance. The 80 day phase wins over time (1/f power distribution in freq domain) but at the outset of the initial move up the 30 day has recently shown enough power to push price around until it’s own phase is aligned. Some examples of this are highlighted below in the charts.
The 30 day cycle itself is phased to be peaking here with a trough at the end of the month. If price moves generally sideways until then expect an explosion of bullish pressure as big and little brother combine at the next trough of the 30 day.
