I think they are only selling big order to large private farms right now they have the technology edge for the moment and they are exploiting it
Their chips are having huge yield issues, I doubt they have sold any apart from the couple they made from their sample chips. The whole "batch 1 sold out" is a marketing gimmick.
Yeah hopefully they will fix their chips and mass produce them with a low failure rate and start pumping out miners and have the price drop.
