One of my 4 Letter Domain Names JKXY.com was just recently bought through my 4 Letter Domain name portfolio www.4ldomain.com for a nice $500.

The buyer from China gives much hope to the undervalued non-premium letters which include QXZ which is considered to western majority as low quality letters. 

I see huge potential with premium letters and one or so non-premium mixed in with that as this sale has clearly shown. 

After November 2nd 2007 after the buyout there has only been one direction that the 4 letter domain names can go, just the same way as the 3 letter min value of 6k and already 5 letter domains are going and that is up in value. 

Whether there are some small signs of weaknesses along the way there will always be a strong demand for this market for both the seller and end user.
