My friend has blocked some good domains since 1999 and he has parked those on godaddy. He quotes £2k to anyone looking for any of those domains and so far no one purchased any of his parked domains.
he has lost around £2k in renewal of all those domains from 1999 but he is positive and thinks that he might get a good deal on at least one of those domains. Recently I took 2 domains from him and he gave those to me as a friend but I know how to make good use of such old domains while he knows nothing about it
as Avatari said, there's no fix price for any domain auctioned online. we can pay good price to get eukhost.co.uk but it wont be of any use for anyone else selling garments or any other service besides
web hosting.
