Strategies for taking profit but leaving a moonbag?

I understand that taking profit can be one of the hardest things to do in crypto and it can depend on a lot of different factors but can anyone suggest some good workable strategies for taking profits but leaving a moonbag for just in case?

Often I think about doing this but don’t because my bag would be worth more if I don’t take out my initials?

So maybe once I’m up a decent amount take out 50% of the whole lot?

Or maybe take out my initials plus $200 (If I’m up that much) and leave the rest?

Any suggestions would be good
