ΣL Cycle Summary
Whilst the superb 30 day cycle has been ‘making all the headlines’ in Bitcoin for it’s wonderful correlation to price action over the last 6 months, the 80 day feature bubbles under the surface. In the latest iteration of the up leg during late September and October price has moved largely sideways, battling with the aforementioned little brother for correlation. It is also interesting to note the power around 60 days, likely a harmonic (see chart below), picked up by the time frequency analysis in response to the relatively high amplitude of the 30 day. The fact that the 80 day is not harmonically related (at least not in an integer multiple) to the 30 day suggests these two (80 & 30) are the distinct and notable periodic features.
Taking this phasing on the evidence, it looks bearish for Bitcoin. Bulls will hope the 30 day (troughing) continues to battle hard with it’s larger brother and push price a little further up against the 80 day’s down pressure over the next week or two. However, it is a fundamental feature of financial markets that power is distributed in a ~ 1/f manner in the frequency domain, so the 80 day will exert it’s dominance in time.
