Guys, I don't understand you here, except it's something not domain-related! There is millions of xyz, XX millions spend on renewals, here on NamePros lot of people selling crap xyz, and single very popular keyword xyz is "zero" $? What are you talking about?
Have a look at how many .xyz registered and how many sell, then look at the prices they sell for? It a waste of money. 99% are domainer to domainer sales
AnyKeywords.xyz almost worthless
Terrorism.Gtld almost worthless & pointless
Put them together ==REALLY pointless, worthless
Listing it for sale for More than regfee = Newbie Mistake
