How to take profits

So I hear a lot about making sure to take profits. So I thought I'd be possibly fun and helpful to get/give opinions on how you go about doing that.

I realize there's a lot of moving parts and there will be hypotheticals, but let say you're going to be right about when your fave coin hits it's ATH. At what points do you pull some profit out? Do you take it all and risk missing the top? Do you do it slowly over time? Do you always hold a small amount for possible moon shots? I just thought it'd be nice to get some insight from others on how to plan out taking profits.
