16K separate rigs?  Why is this not just a large-scale miner?  Who HODLs his/her Ether.

WTF resurrect a 4 year old post?

Close to the edge but should be OK.  I'm running 5x total 480+580's on a 1000 PSU.

If PSU can't handle it, the system will do random shutdowns.

7nm is an order of magnitude harder than anything that came before.  If you're not seeing nVidia or AMD producing or even announcing parts at this node, then you're not going to see real parts coming from a random bitcoin company any time soon.  nVidia and AMD have $billions to invest.  7nm parts will come, but not soon.  7nm bitcoin mining chips will only be used to backfill fab capacity if they don't have other production to run.

Every new technology node is massively more difficult than the preceding one.  Transition to 7nm changes all sorts of things.  It's going to take literally $billions to get this tech up and running.  No one's going to waste wafers on bitcoin chips, unless for fab testing because it's actually a very simple design.  Maybe this is what they're hoping for?  I just don't see it happening.

I'm wondering if our friend Sonny Vleisides has gone to Japan...  This sounds a bit like his type of operation.

Read about mining.  Google is your friend.  No one has been able to mine Bitcoin without using super specialized-hardware for nearly 4 years.  You can buy a R-Pi for $35.00  If it could be used to profitably do anything, you would not be able to find them for sale, except on Ebay for 3-4x retail. 

Unlike most people on this list, I am in the chip biz.  I cannot say much.  I can say this:  A US$300M investment in a 7nm-based chip design will get you pretty much that.  Then you'll need more money to get your chips fabbed and you systems built and installed and everything else.  A few $millions will go a long way towards physical plant for installation, but it takes a lot of money to play in the 7nm game. 

There were some comments in this thread about the move from 22/20nm to 16nm.  The 20nm node was largely skipped by the industry because 16nm node added so much value with the introduction of finFETs, that it wasn't worth it to continue investing in 20nm.  The 16nm node still has a ways to go, and has had a number of rounds of refinements.  I don't know which actual 16nm process is being used by BMT, but they could probably get some mileage just by re-spinning into a newer 16nm process.  If they cared about improving the product.  However they're in a situation where they can sell all they can make, and price is hardly an object right now, so why waste the engineering resources? 

7nm is a huge wall to climb for anyone, and I don't think anyone's going to be building a 7nm miner for at least another year, maybe 2. 

If someone does come along and proves me wrong, I'll buy it.

If they're refusing to provide you with BCH or equivalent FIAT value, they are stealing from you.  They 100% have access to this currency and it should be available to you as the owner.

With BCH running at roughly 20% of BTC's value, you're losing a lot if you can't get access to your property.

Hi,

Free power is one thing.  A megawatt of free power is something else again.  If you can arrange for a megawatt of free power, I would be willing to join you anywhere in the world (subject to your government's acceptance of a US Passport) and help you to build a mining operation, in exchange for 50% of the first year's production. 

Let me know if you're interested.

This stuff costs real money and produces real value.  Free advice is worth what you pay for it.

Thanks for the contest - always fun to try to guess!

This is not yet a guess, just fun with numbers.

If Difficulty were to go up (just) 8.32% this go-round, we'd be at difficulty of 1E12.  I recall late summer 2013, when no one believed that difficulty would hit a Billion by the end of the year.  (It did, block 276192, on 12/21/13)

I've been sharpening my dart this week.  This is a more difficult prediction than I thought.  Thanks for funding the contest!

Really glad to see this feature! 

Too bad this does not work on my systems - fails to start on Linux 15.04 (15.04 Because old drivers are best drivers for old cards, and old cards are best cards because paid for!)

Crashes in seconds on Win 7 box.  Have not installed on Win 10 boxes. 

Waiting to hear more about others' experiences before spending more time.

Don't we all.

This.  This is the only reason there's any price support at all in this turd-based air-dropped shitcoin.  No one who holds BTC in a private wallet can sell because can't deposit anywhere.  Supply and demand is out of balance because the supply is constrained to only coins on exchanges.

Consider this from Bitmain's POV.  They are selling all they can produce.  They're sold out 2-3 months in advance.  What would be their motivation to roll out another version?

I don't know their exact node, but it's something 16nm.  There are several different 16nm processes.  They've caught up with what's commercially available from wafer fabs at this point.

Intel's 7th-generation CORE processors are their latest, and these are on their internal 14nm process.  Intel's not going to open their fab to Bitmain.  
AMD's latest RX 580 GPU chips are on their 14nm process.  AMD's not going to open their fab to Bitmain.  (I know, it's Global Foundries and Samsung)

Others have announced intentions to go beyond 14nm, but these are the technology leaders of the world.  It's going to be a while, and they're not likely to open their fabs to Bitmain for a while.

So what will Bitmain do?  They might consider doing a spin to a lower-power process at 16nm, but that's much easier said than done.  Lower-power processes are focused more on device leakage, for battery life while not in use.  The SHA256 algorithm flips probably 2/3 of the flops on every clock cycle, and it clocks every single one of them.  That's where your power is going.  Leakage power does not even enter into the discussion for SHA256 chips.  Maybe late 2018 for another node.  Maybe.

So what will Bitmain do?  Laugh all the way to the bank.

So I'll throw another 2 Satoshis-worth into this discussion.

You're correct.  Difficulty is not a direct factor.  You have 10% of total, then you'll earn roughly 10% of the total payout.   I say Roughly, because of the random nature of crypto-currency mining.  Some miners are luckier than others in the short term.  In the long term, it will mostly even out.

Depending on the rules of the particular coin, difficulty will change +/- as the total hash-rate affects the rate of production of the blocks/coins.  Your portion of the total is the only thing that affects your payout. 

If you had an Antminer S9, back in January of 2013, you would have been 1/2 of the total network, earning 72 blocks (* 50) or 3,600 BTC per day.  That same machine today is 0.0002% of the network, and will earn you roughly 0.0044 BTC per day.  Until next week, when it will earn you maybe 0.0038 BTC per day.

The difference is caused by the difficulty change since then.

Pardon me, I've got to go over some settings on my time machine...

Time to do a little math.

All this assumes that you can install hardware today.

Network Thash/s Today   6,357,467
Blocks per Hour Today   6.94
Bitcoins per Block   12.5
Bitcoin Value Estimate   2824
Calculated Information as of TODAY   
rewards / day   166.56
BTC Reward/Ghash/S/Day   3.27489E-07

If you can install 110 TH/s, you'll earn:

BTC Reward/Day   0.035015116
Estimated Earning/Day USD   98.88268718

That's 8 Antminers, which would consume 12,000 watts.  You'll burn 12KWh per hour.  288 per day.  8640 KWh per month.

If you have to wait until September, you'll need somewhere between 10 and 14 of them. 

Note that none of this math accounts for cooling.  12,000 watts makes a lot of heat.

Good luck with your empty house.

To answer the original question here:

Difficulty does not impact your individual hash rate.  Difficulty affects productivity of a given hash rate.  More difficulty will slow down the Ether (or any other coin) production of the network. 

Value of the currency is tied to supply and demand only and has nothing to do with difficulty or hash rate.
