I just found that from the past to last week the most of .xyz domain registrants came from China, and the US had always been in third place, but this week things are different the US replaced them as number one. (source: namestat)
The .net, .org, .info are a little bit decreasing progressively day by day, the .com remains stable, on the contrary, the .xyz is increasing gradually if the stats are accurate that's good news to .xyz. (source: dnpedia)
Forget about the .top there is hardly any signed zone at all.
