Why domain have value?
Because it can be used by someone for website address..
How much the value?
Diamond.com is now for sale, Diamond.com surely represents billions of dollars industry, there are millions of people working by selling diamonds, there are a lot of multimiliions dollars companies selling diamonds : Graft, Tiffany, De Beers, Rio Tinto, etc. So it can be understood why Ice.com bought Diamond.com from Odimo for 7.5 millions $. And you can guest how much the owner ask for Diamond.com now...
So, you can ask yourself :
- who will use Nodotcom.org
- how big the industry is
- how many people want to use Nodotcom.org
You can guest yourself the value of your domain
Cheers
