Simple answer is Take profit when you are happy, there is no such thing as hodl forever, what happen if the price is now declining, this is just a example okay, the price goes down from 100k to 10k from the moment the price is going down to 50 you should have already take profit, why because you are again waiting for the next dip and buy cheap,
and hold again, so there is a phase that you should take profit and hold, this is just my opinion, look what the holder that bitcoin selling everything, you think, he will not buy again?
he will but with the cheap price or he thinks its already time again to bag.
