Its a scam miner. registered company means nothing. HEck, a good scammer can register a name (its like 20$), rent a shared office (like really cheap) to get a business address and shit, or even a po box...oh why do I even bother. you arent gonna hash 20ths at 1500w god damn it.
And they can pay them self's from a company and say they are working on it. Keep going till they are empty on cash and close. Maybe a few get lawsuits (even if you do it's no guarentee you get paid).
The only winners in this is the ones that scammed people. No one should be buying them at this point. And really no one should have bought at all. People need to realize rendering does not mean there is a miner.
