When the ATH hits

A bit of a vague-ish question because I'm still new to crypto, so bear with the vagueness of the question and hive me your personal not-necessarily-an-answer experience.

For those who experienced the last bull run... When the ATH(ish) hit... When you realized, oh, shit, it's selling time - my crypto has gone up that much.

What kind of timeframe were you looking at before it was too late to sell? Was it minutes? Hours? Days?

I heard rumors of someone trying to sell and the price already dropping again before the sale went through. Not sure how accurate that was, but y'know... ????

Basically, when your crypto reached a decent selling high price, how quick did you have to be to sell?

(Not counting those of us who hedl through the bull run and sold low becajse this is the way.)
