domain was registered in 2003 ! Sell it ASAP
All the premium names that worth 100k + were registered much earlier.
There are new trends, like blogging that have exceptions. So, blogging.com
may cost a lot, but your name is not a new trend. My point here is that there were people in 1994-1996 that really spent a lot of money paying yearly fees for the domain names, and nobody knew how big the Internet will be. These people could register pure dictionary words that costs 100k + right now. After year 2000 domain name registrations were 9$, and domain name industry attracted a lot of people who were harvesting whole web for good names. Your name was registered in 2003, this is just an indication that nobdoy needed it before that. There are many sales reported on dnjournal.com for domain names that were registered after year 2000, but these just exception, they report only the highest sales that don't really represent the real price on the marketplace. If you are that lucky, and somebody offered you that much money for the domain name that you handregistered for 9$ 4 years ago - my advice to you: sell
