Bitmain just announced the AntMiner A3 - 815GH/s Siacoin miner - Blake(2b)

While feeling sorry for myself for having bought an A3, I started poking around at siamining.com looking at the stats on their "top miners" page and came across the #1 miner:
https://siamining.com/addresses/0104ceeee0c1335e6770b9e620baa87615e1780ea1a5e6bca2df2651c92313f9c3aa56865535

This address has 415 workers, each of which is running at 3Th/s to 4Th/s producing overall around 840Th/s, generating 533,993.75 SC in the last 24 hours, which at the current (0632 PDT 4/27/18)  value of approximately $30 per 1K SC is 553 X 30 = $15,900 per day!

How is this possible? An A3 produces 840 Gh/s, so it seems like it would take 1,000 A3s to produce 840Th/s. Could this be Bitmain running their own (unavailable) miners that they have built to a 2 to 4 Th/s spec? Who else could do this?

Of course, even Bitmain has to pay for electricity, but I would tend to think they would locate their miners close to one of the massive hydroelectricity dams in China or have a monster solar farm to the west of Beijing in the Gobi desert or something equally wild.

Could also be Halong mining - there is a 3.83TH Sia miner called the B52 on their website.  Haven't seen any reviews on it yet, but you know how these ASIC companies mine before they sell so they are probably running many already.

Halong and Innosilicon have been flooding the market with 3.83 TH SC miners for a while. Those units are priced extremely high hence there are not many reviews available

I feel opposite; I bought two A3's for $980 each and expected a total loss on them, and sure enough they dropped to making $6/day before electrical, and now they are up to $15+ per day I am floored.  If Sia keeps rising, who knows.  The Halong units are actually more expensive per hash than the A3, Bitmain's next A3 batch is only $520 each which is much cheaper than the Halong per hash.

The difficulty will be such that at the point the $520 batch is done shipping, daily will be back down under $10. A rise in the coin value does help though.

(also if you held your earlier coins, you actually made a lot more than $6/day )
