I'm ignoring them for good reason: They have not been vetted.

hmmm, i think u have overlooked the coming new Boss in town:

"Can" is key, but 200 units a day like Knc did with Jupiter means a batch of 1200 complete in 6 days, so I beg to differ.
1200 times 3 or 4 Th/s in 6 days......  (up to 4.8 petahashes) how is bitmain supposed to touch that?  Can bitmain ship 4-5 petahashes per 6 days.... I think not. They can "ramp up" all they want, it won't change things much, especially after Neptune.

It goes to show how fast Bitmain can ramp up production. KnC was never able to pump out the vast quantity of units that Bitmain does.

Can you explain how that statement equates into larger diffchanges over the next couple months?
I see absolutely no relevance between Bitmain's current total network share, and future diffchanges.
I have nothing against Bitmain, just sayin... enjoy them while you can, because when Neptune ships, your returns will be squat, whilst Neptunes will have the horsepower to return for much much longer profitably. Remember what happened to Avalon's and BFL's when Jupiter came to town?
This is a similar comparison. Yeah, there's gonna be one or two nice big diffchanges when Neptune delivers, but after that....  Who has the capacity effect the diff over even 5% in a single diff after Neptune comes to town?.....   NOBODY.
No single batch delivery from a single vendor will ever touch 5% of the network again after Neptune. Take that to the bank.

Damn, that's right. My closed mind was thinking US only. What sucks is today was about 65 degrees out and my October rig temps went up 5 degrees just because of that. It's gonna suck trying to keep this thing cool. Without a miner my average electric bill in the summer months is about $400. I live in NJ. I do like it cool, cooler then most can take it. If I could keep my ambient temps in the house at 65 all the time I would.

How the hell did you guys keep your miners cool with such high temps? Just put it in front of the AC vents or something?

He's lost touch with reality.  That's what happens when you start to believe your own shillin'.   

Sounds like you haven't kept up. In a few short months, Bitmain is powering 20%+ of the entire network!

which may make up a whole 5 to 10% of the next couple diffchanges, I see no real threat there. I really think you're over-estimating Bitmain's impact to the network, and underestimating the Neptune, and KNC's ability to deliver. One thing for sure, the boards you are getting from bitmain are not ever going to grind out much more horsepower than you get right out of the box, after applying available tweaks... etc. Neptune...we have the possibility of much more than 3TH/s much more.
If we end up with 4 to 5 Th/s in Mid to late April....     could happen, and actually highly likely IMHO.

interesting...BTW, I used May 1 as start and 50%/mo rise in my calculation (~14%/cycle), which is less than genesis block, but more than your numbers. In addition, Bitmain has targeted KnC theoretical hashrate (3Th) in $$, but they already sold out of two batches on April 1 and 10. KnC , of course, has much higher efficiency, but unknown final hash rate and dates. As such, it is still possible that they could be superior IF delivery can be assured by mid April. I am not sure, however, how modular Neptunes will be as far as power supplies requirements-knowing knc engineers arrogance, they could ask us to provide PSUs that are simply not available. In any case, I am on the edge as far as refunds are concerned. Honestly, Bitmain S2 does not look much of a bargain right now, especially with low BTC, but if they drop the price to $3K and below-it might become very competitive fast.

Forget about breaking even. That would have only happened had KnC shipped in Q1. Well, that's not going to happen, so it's over for Neptunes. By the time Neptunes ship, difficulty will be 10B+, at which point a Neptune will generate less than .15 btc per day. That puts RoI at over 3 months without even considering any difficulty increases! Believe me, there's lots of difficulty increases still to come. Bitmain knows how to scale production. They're going to flood the market with 1 TH/s machines before Neptunes even start shipping.

Sure.... well, firstly, I have a 10k neptune, not a 13k neptune...(CA Batch) so, your numbers are a tad off, but I'll show you easily what my rationale is with one simple chart. Look at the last two charts on this page: (they are same chart really)  http://bitcoin.sipa.be/ I'm lookin' at a steep decline in difficulty growth. Looks to me like a few mining calcs are waaaay off. Most of the competitor Asic companies "Just shot their wad" too. After Neptune ships, we will never see another 10% diffchange; which puts the next max monthly increase under 30% maybe closer to 20%. (and I only mean 1 or 2 months)and it will dwindle further from there. I also consider these numbers "Conservative"           Now, consider 4Th/s, or even 4.5Th/s
when using Genesis Block, remember it is averaging the %monthly increase over an entire year...  Now think over the next 12 months, what do you really think the average monthly increase will be?   (closer to 6.7 than 67 for sure, lol)  Plug that in.  OMG, lookin good.
This is the Pre-Jupiter scenario on steroids brah; and this time around, the diff change increases are dwindling, not increasing.
My numbers, even at 3000 watts, paying .43/KWhr look really, really good.

*We went from 40% diffchanges in November at it's peak, and now, only 4 months later, we are having 11% changes.
How about 4 months from now, 4 months from then, and 4 more....   hmmmmmmmmmmmmmmmm
Also.... If KNC ends up pulling another hashpower doubling after delivery and a few firmware tweaks like last time?.....  
(and I'm not counting on that, but it's not out of the realm of possibility)
    

Hey, I am curious about your bullishness on Neptune. With btc being where it is today, one can get at least 23 btc per Neptune if cancelled. I still did not pull the trigger, but it is getting close. What is your rationale? I don't see anybody paying huge premium for the machine at these btc values or machine mining more than 15-18 btc optimistically if hashing starts on May1.

I can certainly confirm they run well in "Hot" weather.  
All my KNC machines actually ran best when the asic temps were 75-80C
I'm in Hawaii, and I still had to remove the case fans to get them that hot.
But Neptunes could bring entirely new characteristics as it's an entirely new ASIC...
But indeed, keeping the house cool with them inside it is a COSTLY idea.
Save your $, and just ventilate the room with a cheapo boxfan in the window.
It won't take too many units to totally overtake a 10k or 15k BTU aircon anyway.
Ventilation is most efficient, hands down.

I have had to do this type of thing before - remember the output (hot) hose needs to be double-walled (insulated) otherwise it just acts as a radiator and dump the heat back in the (cooler) room before it can get outside. 
No point making it less efficient than it already is. 

The Aussies had a pretty brutal summer this year.


Edit: Derp, Merv's post wasn't showing for me.

don't forget these were shipped all over the world and here in Australia (Melbourne) we've been through one of the hottest summers on record.  10 days or more between 40 and 44 degrees celsius and more days over 35 degrees celsius.  I have 3 october jupiters and they all ran without a problem, without extra cooling or air-conditioning.  but I did move them out of the house into the garage.

hope your are wrong but i'm in minnesota and if it is that bad i intend to chase down a used house sized a/c unit from a demolition or some such ...just pop it on some blocks in bsmt.....wire up the a/c part of the furnace...vent it out a window using that long plastic tinfoil ducting....and just crank it up according to temp to slam the basement with the neptune..it is ugly dumb but a heck of a lot less in elec then a huge 220 wall unit in the window of the upstairs computer room....heck at that point it wll just be me getting enough motivation to duct the rest of the house (i'm cheap but also lazy) anyway....my take on this but i know contractors ...should probably do this anyway just to get me motivated to a/c the house

Searing

All of the first KNC hardware came out in October if you remember. Beginning of winter and cool months. They have never been through a summer yet. Hazy, hot, humid 95 degree temperatures. That's what everyone has to look forward to. If I had the opportunity to get a Neptune or opt for cloud, I would definitely take the cloud. I could never keep a Neptune powered up all the time and keep it cool. Not in the summer.

Not my diagram, but thanks.
