BTC's ATH and cycle high is 61781 (Mar 13). At its current rate of closure, the pi cycle crossing should occur in roughly 18 days. While the crossing has occurred within 3 days of the prior 3 cycle tops, this indicator was developed and backfit to "work". Thus is it backward-looking and due to lack of data points, has never actually been used to predict a prior top.
By definition, the pi indicator would be INVALIDATED as a predictive tool if a crossing occurs before BTC re-establishes or surpasses its ATH within 21 days (18 + 3) and this turns out to be the cycle high.
Thus, if the pi crossing occurs prior to the ATH, it is possible that 1) BTC has not yet reached its cycle high, 2) here will be a double pi crossing, or 3) the pi cycle indicator is, in fact, useless due to the nature of its development as a backlit indicator vs a predictive tool.
