I understand that it was a business sale and not a domain sale but it is another good End-User using .XYZ.
Abc.xyz Starship.xyz Engine.xyz
Those are three other noteworthy End-Users. There is a long list at ...
There will be end users in every extension ... particularly new ones as some start-ups try to gamble ahead of time on what will be the next hot new TLD ... but at the end of the day if you take the ratio of built up end-user sites divided by the number of domains in circulation and .xyz probably has the smallest fraction of % usage.
This new news will definitely drive up short term sales and speculation .. but the real question is if it will actually drive end users to use/develop these domains .. or more likely simply inflate the .xyz bubble even further?
Their price points make the answer to that question almost impossible to tell. At pennies for first year registration these domains are essentially free ... it's not a business model that lends to easy evaluation.
China is a very weird market .. the growth/bubble last year had little to do with actual usage of the domains and more to do with the money market and unusual loan system over there. It's something that's very hurtful to domains in the long term as it creates artificial bubbles (although I guess if you sell on the high side of the bubble it can be good for you .. but this bubble isn't based on domaining fundamentals at all).
Obviously if you have/get great key-terms left of dot at $0.01 then there really isn't anything to lose .. you'll definitely come out a winner at this point ... but with millions of .xyz domains already registered by domainers the real question is are there any solid domains left in significant numbers (because yes .. even in .com the odd great one can still be hand regged .. but I think you know what I mean)?
At the end of the day this is actually more "non-news" than people think .. as the real news would be something that generated more end-users .. which for us would mean more RETAIL sales at better prices. This news simply moves a small handful of low-end .com sales over to .club and .xyz ...
At first thought without looking at the numbers at all, is that although this is good short term news .. but I'm thinking it's completely insignificant compared to the crushing drop for .xyz next year when the $0.01 registrations face full price renewals.
Combine that with the fact spammers flock to the lowest price extension and I'm not sure if I'd want to be holding anything but the top 0.01% left-of-dot .xyz domains next year (ex: single-key-term, LLL or less, NNNN or less, short-Chinese-terms, etc).
At the end of the day there are WAY too many .xyz out there to justify the demand .. plus the sale price point for most of them doesn't justify holding them longer than 364 days .. at that point will you sell enough to make it worth your time/effort? My guess to that answer is "no" for pretty much any .xyz domains still left today .. the only exception is possibly Chinese speakers who have tons of time to go through a lot of possible terms and popular play-on-words not registered yet ...
