How to properly list domain?

[Domain noob]

I'm confused with afternic and DAN. do i have to list on both or just 1 and which name sever to use?
What's the best way to list your domain?

List on both. Better use the Dan's nameserver ns1/ns2.dan.com, if you don't want your potential buyers to see a https warning (Depending on their browser security settings) and just directly load the salespage.

Listing on afternic as well will get your domain more visibility with the help of their domain partners.
