After reviewing this paragraph, I thought of something. ANY country domain name, no matter how obscure the country is right now, will be worth a ton of money in the future. Sorry about the confussion. The last factor of worth is present domain development. Development, too, can be a positive and negative factor.
Most buyers wish to buy a domain that is clean or never used.
The same is true of a domain. Most people won't want to buy a domain that was a result of a failed business attempt. Besides having already, in the internet's infancy, failed in business, the site may also have unrelated rumors, search engine submissions, newsgroup articles, etc., floating around the net which you may not want to be connected with. A site that is doing good business and making money confuses me as to why it would be for sale, but it does happen. Good luck shopping.
