Where is all this D3+ info coming from ?
The D3 already eats 1200Watt.
In case they double the Asic-chips on that guy (thats how the L3+ was born) it will eat 2400 Watts.
Assuming they just double the ASIC-chips and size of D3, you have a franken-ASIC.
So the next possibility: bitmain has a more efficient ASIC-chip in their sleeves already.
If so, why did they release D3 at all ? If i read it correctly, bitmain has never done a NM-shrink so quickly.
All in all its not so likely for me. But who knows
time will tell
smaller chips
edit: they only liquidate their in house machines once they have more powerful stuff already in, and are clearing up rack space. If they're selling 15gh, they're running 30ghs already. If they sell 30ghs, use your imagination.
Another reason is once they clear an entire production line of a miner, and the profitability is rock bottom, people stop buying. They'll stop selling. At that point, they can liquidate hashed coins (by the millions) into bitcoin or fiat. Either for further investment into the company, or for pay-outs.
No hardware to sell, no reason to hold back & prop up the coin.
