" Deal " ?? Delivered price at .058 per KWH is a 555 day pay off. @ .048 per KWH it's 437 days. How is that a deal?? Nope....keep trying Bitmain. Even without tarriffs that metric is horrible.
Size and form factor are also an issue, and I can guess it's 16nm chips or else they'd gloat about them, so reliability might be an issue as well.
I usually don't recommend this unless it's true, but better odds to hold onto coins, wait for difficulty and price to go up from all the new miners and profit via holding.
I'm looking for a new miner to replace my S9 and 821, but so far nothing has worked out to be a winner unless a random sustained price spike happens again.
Which once again, simply holding coins would be better.
By the time any of these near 1K in cost miners get delivered, difficulty could start going back up, or price may collapse.
Seeing how much efficiency numerous companies have been pushing out for 16nm magically right after they no longer turn a profit for most people, not just AB but also low power modes, the S15 and others will probably have a super efficient batch coming in half a year, once the companies start replacing them with the next generation.
