This name has nothing going for it other than it only being two characters long. There might be a lot of two character names flooding the market soon on top of that. So value the bare minimum 2 ch dot cc. Ill take NJ's "maybe mid $xx" as that. Good luck and dont dislike people giving an opinion in the section that begs for them
You know, leaving bad rep will not increase the value of the domain.
The fact that it was still available to be registered indicates nobody thought it was worth $30 or whatever the regfee is.
I don't see any market for that name, or the extension to be honest. You'd be able to get your registration fee back to a reseller, and to an end-user...I don't think there'll be one for the immediate and mid-term future at least.
