is it wise to BUY revenue domains from someone in order to just park it again? or should one only do so to develop? just wondering on your opinon
Well if the domain is making money as a website, keep it going, if it is being parked and making more then you could developing it, park it .
Unless it is a very good generic name say for e.g. cellphone,flowers etc., it would be wiser to develop it as the domain would gain in value.
