The A5 is more efficient than the D3. And yes, that does matter. I don't understand what you are asking.

How is the market caps between the Sha256 and X11 coin algorithms relevant in determining profitability?

I don't know What the 24.83 or 80 numbers represent, but yeah inno is still much more efficient. I don't agree that X11 mining is burnt. It would be, only if some manufacturer releases something more efficient than the A5, but if not, then I can see it still being profitable (if you can reach ROI in a a year or two with the A5... but that might be asking too much)

Think of how long the S9 has been out, and it's still the most powerful. There were a lot of people complaining about it's price point when it was first released.. even though it was only 1/4 of the price of the inno...

If the A5 remains on top for a while, I think it's still profitable in the long run.

Yes.. but then the electricity cost would be about $8,500 a year, and you would need to have the power hookup to support 8400 watts.

Also, as the mining difficulty of Dash mining goes up, and the cost of power starts to equal close to the same amount as the Dash that has been mined, then you would be forced to shut down because there is more efficient mining equipment being run that are most efficient and draw less power.

Don't forget that efficiency (J/GHs) is everything in mining. Looking at GHs alone without considering the power consumption would be a gross negligence. Max GHs is only profitable when the mining difficulty has not caught up, as soon as everybody joins in, then it's a game of efficiency.

Don't get me wrong, I know that people who bought the A5 might not ever get their RIO, but I also believe that if that is the case, then anybody who bought the Antminer D3 that doesn't get in early enough will have even less of a chance.

The bottom line is that profiting off of an Antminer D3 means that you were able to plug it in and run it before the difficulty got to high. As soon as that happens (and it will happen because only the most efficient survive) then it's game over and either you came out a winner or a looser.

Profiting off of an Innosilicon A5 means that you were able to run it for over a year without competing with a more efficient miner ( Which does not currently exist, but we will see eventually  )

Currently, there is a better chance of getting a ROI with the D3 because of it's price point and current difficulty rate. Once the Innosilicon A5's take over, it's only a matter of time before it costs more to run the D3 then it makes.

Given the current Dash mining difficulty, it will take around 8 months to break even on the price.
By the time the miner gets here, it will most likely take over a year to break even on the miner cost seeing as the difficulty rate of Dash is still skyrocketing.

Innosilicon just released a video of the Dashmaster A5 (not really in action.. but in physical form at least)
https://youtu.be/9nyIewRpB4U

They state in the video that "32.5Gh is achieved with only 720W in our standard default mode. That is over 3 times more power efficient then competition in market" which is actually true.

Innosilicon:
32.5Gh / 720W = 0.045139Gh/W

Antminer D3:
17Gh / 1200W = 0.0141667Gh/W

If the specs check out then inno might still be profitable as a long term investment where as I see the D3 as a short term ROI then trailing off when the difficulty becomes to high to remain profitable. I mean yeah, the ones who bought the first batch of D3's probably will get their ROI soon already.. but in the end.. only the strongest survive!
