interesting thoughts from Inno branch:
Once the Dash difficulty reaches 65 000 000 then D3's will officially cost more to run than they will be making. (at current rates ect..) The difficulty is at 36 000 000 as of the time of this writing.
Contrast that to the A5. The mining difficulty would have to reach 180 000 000 before the A5's are obsolete in the US (given average US power costs.. other areas will vary). If the A5 used the same power draw as the D3, then the network difficulty would need to reach 110 000 000 before profits are lost. Either way, much better than the D3 of course.
I thought I recognized that post
thing is once d3 becomes unprofitable, i mean once it will lose money instead of making it most of D3 owners will switch it off but it depends on electricity rates, so some will switch it off earlier some later, but thing is because of that difficulty wont become more then 70mil, i dont think that innosilicon can deliver such amounts as bitmain, and even if they could d3 will be switching off and that will balance out difficulty. this is not good thing for us but in case of difficulty it will balance out
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.
