I've a personal PBN, should I sell some link?

I've a pbn with 20 websites maybe, all blogs are good, half of them are what I consider very nice.

No tweak on the metrics, all manual builds, all uniques, But I've only few money website to promote with and sometime I publish article without any link or to website who don't even pay me

Should I sell some link here? At least to diversify my links, or someone want to exchange some links with me maybe? It's a French PBN, about fashion/shopping.

I was thinking about this and I don't know if I should do that.

thanks if you can give me some advices about it.

What's about metircs?
Moz: DA/PA , S.S, Root domains?

all domains are different etc... but that's not the question I guess, I can provide exact metric if someone is interested, but the first question is if I should sell or exchange links to diversify my links, and if someone is interested

You can't sell them here unless you open a sales thread and you do not have the qualifications to open one here so I'm going to close this thread out as it fits into the category below.
