If you check recent sales of all 4 letter domains (non Premiums) they have all declined by $100 dollars in the last 2 months in the "reseller" market. Yes, if you are lucky to have cvcv's maybe the value is holding, but those have also taken a hit. Even the Chinese 4Letter.com's have taken a beat down and have declined by $800. Say it ain't so? Chiese premiums were $2,000 few months ago. Now? A good friend of mine that is a top domainer said to me "sell all your 4 letter domains while you can". This is why I'm selling all of my 4 letter dot com domains. Time will tell... But history does not lie.
