These are average rates taken by the US governent for census purposes.  But they are not totally accurate as they include the wholesale cost and another expense, but they do not include the use of delivery line and another charge which is about another .04 to .05 that is not refllected in that chart.  So delivered cost is about .04-.05 higher. When the consumer get the bill.

By US States:

Average electricity rate in US is .16  it can vary as low as .08 in Washington to as high as .37 in california and new york.  MIne here in PA is .16 total, you are looking at rate of electricity cost and delivery, etc.  This is total cost on your bill.




Most sources dont have the total cost.

Add another .04 to .05 to the US for correct prices, for delivery,   for the transportation use of lines etc.

Hashrate goes down when price is rising, now hashrate is goin up while btc price is falling.  

99.5 Billion now

Energy use is secondary now that hashrate is 99.5 Billion and rising.

Ghash loses money on the regular hardware miners to make it back on cloud hashing and reselling hash.

Remember it was $440 last month, so still up alot.

Needs to be $1000 to roi.

Lol this is true.   Anyone who thinks they are buying new equipment may want to try Tiger Direct.

They lend out money at high interest rates and there are enough btc gamblers that are willing to pay it so they can play in the btc casino.

Conspiracy theorists will say insiders knew of the Expedia news and bought 1-2 weeks early. Then sold off near the peak.

Because the s1 is not as power efficient as the newer designs.  And it is past their 6 month life cycle.

The key ingredient here is to use people's pre order money to currently mine then resell the used equipment at market price and keep lowering as diff increases but they are mining them in meantime.  They can go as low as their cost to build the machine.  They get away with what they can.  No one wants to be a hero now with the difficulty rising and with buyers buying less equipment as they suspect the jig is up. Meaning they know the game is  up soon.  

Companies in China can design and manufacture faster for themselves.  Such as bitmain and others.  Less r and d now because they improve what they can from previous gen. Not trying to be pioneers as time is too much of a risk factor.

For ego maybe but its not cost effective:

It cost maunfacturers $500-600 per TH now and thats only 1.5w/gh performance, KNC cant even buy at price because they dont manufacture the chips themselves.  Prob cost them  $1000 TH to build their machines.

and some miners were hoarding mined coins to sell when the price went up

Shouldnt drop below 500, if it does next major support is 430.

"1.  How do you know what $/GH and J/GH KNC are going to deliver in the Neptune ? (hint: you do know that the Titan has gone from 100mh to 400mh since it was offered for sale … what will you do if KNC deliver a 12TH Neptune ? Cancel your SP30 orders ? Sorry - no refunds on SP30 orders … )

2.  How do you know what kind of manufacturing capabilities KNC has so that you can confidently say "shipping out obviously another 30-60 days after batch 1 is released" ?

3.  Do you have a prejudice against the Chinese ? FWIW Chinese companies like Foxconn probably make half the stuff you own, including your IPhone, and their QC is excellent.

4.  If RoadStress is so confident that the SP30 is such a better deal than the Neptune he won't have a problem agreeing to match Neptune $/GH and then we can see what KNC ships. If its a 3TH machine, he hasn't got anything to worry about. If he won't agree to match KNC, then he's just trying to dump SP30 machines at the best possible price before KNC ship their monster Neptune machine. Thats what shills do."


I am  well intentioned unbiased.

1.  I dont know final mining specs for knc jupiter or titan, but they dont have any working prototypes yet for wither machine.  Why would KNC deliver 12TH Nptune if they took all the money 21 million for the suckers that prepaid already and they only promised minimum 3TH?  they are not stupid.  As a matter of fact they can still sell 3TH Neptunes for 6k

2.  It is possible KNC can ship faster that scheduled.  But also possibility they can delay again, even the promised cloud hashing compensation is late, so you think about their credibility.

3.  Chinese makers are the fastest, thats why im sure they are studying the KNC chip design to see if they can improve on it.

4.  We will see, as its a possibility KNC can ship in July so thats earlier than the Sp30.

All depends on shipping any real product out.

Still if KNC only ships 3-4TH in earliest July timeframe the 1 month headstart is probably not enough in savings to a 6TH for 5k in August.  This includes the Free 3TH Neptune KNC promises after Batch 2 is finished shipping out.

Lets see what Bitmain can do this month.  lol     As its a good time to take some market share if they stop being greedy.

Nepune batch 1 was 12k, Batch 2 is 6k  But batch 2 customers have to wait until batch ones is finished shipping out obviously another 30-60 days after batch 1 is released.

Thats why batch 2 its 6k cheaper than batch1 Neptune.  You know this already

So you trying to compare Batch 1 or batch 2 neptune to sp30 on price is utterly stupid.    not to mention they are less powerful and use more energy.   The Jewish also have more QC over their manufacturing than the Chinese-subs KNC uses.

However KNC might have a better time advantage  if they can actually come out as they claim at end of this month, and then really push the batch 2 late July-early Aug.
