Did anyone asked bitmain regarding unshipped power supplies?

I thought I recognized that post


I agree that many D3's will be forced to turn off soon after the A5s start running, unless they have much cheaper than average (or free) power.
I think that too many people saw the false potential to make $150 000 a year with a D3 using one of the online calculators and went all in as soon as they can.
There hasn't been a investment mining "opportunity" that has ever had potential to yield as much as a D3 or A5 so I think that's why the difficulty has shot up more than most had ever seen coming.

Eventually in the long run, things will even out. People will take their losses, and the D3 will end up making roughly as much as the Antminer S7 does in Bitcoin now, and the Innosilicon A5 will be making as much as the Antminer S9 is making in Bitcoin now. It's a rough estimate, but it makes sense as the performance of the two (Dash miners and Bitcoin miners) are somewhat similar. This is a comparison that doesn't take into account price fluctuations or market size and impact or Dash.. we will see how that comes into play eventually.

Currently the Antminer S9 is more profitable in Bitcoin than any Dash miner on the market. This is proof that the Dash mining difficulty will not be able to continue on it's exponential increase. Otherwise, everybody will soon be mining at a loss, and I hope for the sake of everybody that nobody is doing that.

There is one other scenario that I hope is not true. Because Dash mining has just exploded with interest and is relatively new to the corporate mining industry, I believe that it's possible that corporations have managed to create more efficient miners (more so than the Innosilicon A5) and are just running them themselves without releasing them into the public. If this were the case, then nobody else would have a chance, and Dash becomes a centralized garbage coin.
