I am not expert, but I think there is no value.
Of couse it can be sold, always there is somebody willing to buy the domain because of a lot of reasons..his own reasons and there is no logic in it.
But when I say no value I mean there is no who offer it to.
There is no valuable keyword to get daily offers, even a low ball.
Nobody knows why AnimalsUnited.com was sold for 39k, maybe even it was not sold, maybe there was just payment issue.
But if AnimalsUnited was sold it doesnt mean UnitedBirds will be sold too, and if it will be sold one day who could garantee the price will cover all renewals?
For me it is reg fee.. but it could be sold because sometimes domains get sold.. who knows why...
AnumalsUnited.com even is not developed... why knows what was the real reason of this "sale"..
