In previous bull cycle that lead us up to 20k (@ 100% fibonacci growth curve), we had two major 40% pullbacks. However, each time we had a major pullback we had a major pump of up to 150%.
If we were to have a 40% dump, we'd match up to the 61.8% fibonacci retracement; and then say we have a followup pump of up to 150%, we'd peak at 127.2% fibonacci retracement.
