I decided to do a quick qualitative search to see if I could catch some developed xyz sites. While browsing the web over the past few months, I noticed myself on several xyz sites.
Now, I decided to type "win" and ".xyz" in a google search and randomly clicked a few pages off Google. I selected two .xyz domains have been renewed.
http://giveaways.xyz/
https://myluck.xyz/
Both of those sites were started and renewed at least once, and it took me a lot less than 5 minutes to sort through the results to find them.

I can't make a statistical analysis. But if I can find this in less than 5 minutes using gibberish search terms, I find that to be an impressive statement for .xyz
