Some times it is hard to just believe how some of these domains are sold for so much. I see and even have my own domains that are better than a lot of those on the sale list but I couldn't get $50 here on dnf.
I spent many years trying to figure out why somewhat dubious value names sell for lots of money (sometimes amazing amounts of money) as reported in DNJ, but much better names never sell at all or very low prices on forums.
The main reason suddenly dawned on me a few years ago. It's mainly because there are 10s of millions of domains and 100s of 1000s of potential buyers so what with such vast numbers it all boils down to
luck. Even if less than 1% sell it's more than sufficient to fill the DNJ pages all year due to end-users wanting a specific targeted domain for business use.
That's why I pay little attention to DNJ sale reports (but keep up the excellent work Ron) and other venues anymore (some weeks not even reading the data) since most of the sales are basically due to luck and not much more with the *sales venue making no real difference since it likely would have sold regardless of where it was listed for sale.
The main exception to that are *Premium Names at GoDaddy where IMO the names may not sell unless listed as a GD premium listing, but that GD advantage only applies on names priced under 5k I believe (and applicable to people who only use Godaddy to try and freshly register a taken name).
A more or less perfect example is All.biz being sold for a phenomenal $61,750. i would peg its value at a fraction of that (my guess is under 5k, maybe 1k or 2k) so why did it sell for 61k? The answer is probably in para 2 above (one in a million type of luck).
