I do not know much about this site and I have seen their domain to have been registered for long, this should be of of the old cloud mining sites that make use of hyip that will later go bad and many investors will later lose their money.
BitMaxz pointed out earlier, people pick up aged domains from auctions, not allowing the domain to be dropped and then registered again thus keeping their age so sometimes this might really be misleading, especially with mining gear sales.
The domain had nothing on it for years, probably registered on a whim and then left it alone

While brand new sites are an instant red flag nowadays age on the other side doesn't mean really anything if we're only talking about the domain and not the actual website.
