When to hold and when to fold?

I don't have a lot of crypto, few thousand. Up 250% or do as I've been holding a while now.

I've been thinking of cashing out. I don't need need the cash, but it would certainly help right now. It would clean my debt and I'd probably sleep better on that front, but would have crazy fomo if something had a large movement and I missed it.

I have this emotional attachment though, that if I sell I'll be missing out. But also know I'll be able to get this amount back into the account by year end. Although if I was starting over I might go gold Instead of crypto.

How do you take the emotions out and make rational decisions?
