Aside from some small speculation in new TLDs, I don’t really buy anything other than .COM domain names. In fact, I looked through my Moniker account where the bulk of my domain names are registered, and around 2% are not .COM names. 2% may even seem him to some people, but keep in mind that this includes personal names like ElliotSilver.net/.info and other protective registrations rather than investments.
I recently saw a couple of decent keyword domain names for sale in a domain forum, but because they were in an “alternate” (not ccTLD) extension, the price was pretty low and there were still no bids. One name would be a high 6 or low 7 figure city.com domain name, but the owner was asking for under $2,000 without any interest or public offers. I also think this domain name in its country code ccTLD would be worth several thousand dollars.
It got me thinking about the value of non-.com domain names (I was not considering ccTLD domain names). In your opinion, what is the least valuable domain extension? Feel free to post the reason you think the extension doesn’t have much value. This is more out of morbid curiosity than anything else.
