First, read this article to see where i am coming from http://www.popsci.com/popsci/technology/0d796852421b3110vgnvcm1000004eecbccdrcrd.html please appraise these domains spittests.com salivatests.net Thanks
If the article is real then your domain name will have good value in future. Medical related terms always get a good value but it takes time to find a right end buyer.
its real, heres a couple of other articles http://www.foxnews.com/story/0,2933,153953,00.html http://www.citynews.ca/news/news_9026.aspx
I haven't read the article but here is the question- How long in the future will your domains become valueable?- It would be hard for anyone to appraise based on future value- Time makes a big diffrence- A domain sold for $14k last year sold this year for $250k, So it is impossible to even appraise for anything more than present value- Afterall if the seller knew last year he could make 235k more he'd have paid $10 bucks and held on an extra year wouldn't he.. With all that said domain present value- Reg fee, hold on to it and see how valueable it becomes
