Noob question: how do you take profits?

I think the hardest thing to do in crypto is to hodl, even when everything is melting. Then the second hardest thing is to take profits. Because we will always feel greedy that it can go higher.

Is there a strategy for this? Do you decide on a certain fixed exit price or do you DCA out? How do you decide what the DCA targets are – just based off the last ATH, or percentage based? E.g. every 10% pump, I sell x portion

How do you know when to take profits and when to hodl? Also, am I supposed to take profits now and then when there’s a pump? Or would it be better to keep it staked all the way?

TLDR: struggling with profit taking, any tips
