Merited because of an interesting opinion, but i don't really fully buy the thesis that cycles are bound to increase in length since they are being driven (apparently) by halvings. In addition, if ROI are decreasing, but drawdowns stay the same (around 85%), then I just don't see whay it would continue in this pattern. I would reluctantly agree IF drawdowns were smaller, but so far they are not (to a significant degree).

It's like saying that since this summer was unusually long because of balmy weather it would mean that the next one would be longer still.
