Bitcoin Time & Price Cycles for Jan – Mar 2018 For this study I used the three cycles which had the highest Pearson Ratios of the top 100 cycles. When all three cycles sync-up, a high or low should be expected. The cycles used were the 58.70, 47.64 and 55.10. Cycles of this length do not sync-up very often. The actual highs and lows are highlighted in yellow. You can eye-ball the correlation between the cycle clusters and the actual highs and lows.
