I couldn't imagine that there is someone can start a business with .xyz domain.. useless site. most of the gambling site right now are .io and .com
If you are start big business you should go in tld .com domain. And .io domain is very expensive unlike .xyz that you can just bought it for 88 cents in name cheap.
From the domain itself we can really say that the owner does have the capability to ran off a legit site since its not really appealing for potential partners on investors when seeing up only the domain which is useless at all. .xyz is almost free and you should think about that.
