No speculator can accurately predict when the bearish market is ending, crypto market is very difficult to predict thus some crypto analysts based their analysis on calculated guess which doesn't work even technical analysis has it own limitations because crypto market do defies TA most of time, thus the start of Bull run is unpredictable we needed to buy now using DCA meanwhile crypto traders do trade the market irrespective of the market conditions whether bearish or bullish they enter a trending market and trail stop it till the price revises.
