I subscribed to their channel on discord. I'm noticing that several want to sell this hosted device for $ 650. In fact, if it only makes 1 Ghs hns it is not worth taking it and therefore I would orient myself on hashaltcoin. But they told me that HAC makes frequent disconnections, they move often and stay for a week, so I would still be undecided. Apparently some are waiting for the refund because they have not managed to make the stream ethereum but I would like some more precise news.
