What makes an unused domain worth keeping?
Brand idea, niche, crypto or Web3 potential, old links, or just not wanting to lose it?
Yeah basically those, you already have the answers...
You know;
The forum allows you to post your service's announcement thread [ANN] if it's somehow related to Bitcoin or Crypto.
If your website accepts Bitcoin, there's no issue posting it in Service Announcements board (
link: Service Announcements).
If not, but Altcoins, then there's an Altcoin counterpart of it in Altcoins section (
link: Service Announcements (Altcoins)).
Don't forget to note that it accepts a specific cryptocurrency.
Basically free advertisement and you can have a place to answer the concerns of your potential customers from Bitcointalk.
