$50 or some such - like I said, pricey.

In theory, yes - but the odds are prohibitively long, to the point of "don't bother trying" give the electric cost to achieve 1MH.

 Cell phones don't tend to have highly powerfull CPUs, and since you can't turn the rest of the device off they're actually very INefficient for CPU mining overall.

I missed the date on the original posting, so let me rephrase.

 Can we stop resurrecting ancient zombie threads?

 

My only issues with Zoomhash are that their warrentees tend to be crazy-short, and they tend to be pricey....

blueprint of the layout would be nice in the meantime?

You're STILL looking at peak rates - the long term rate is still well under 500, though the increases since your original post might push to 500 as a non-peak average in another couple weeks to a month.

 We are NOWHERE NEAR your claimed 606 as anything but an instantanious PEAK rate.


 There is already a recurring thread predicting hashrates, no need to start another one.



 Winter has very little to no effect on major farms - they MIGHT be able to push their hardware a little harder, but it's NOT a big difference as they have serious cooling efforts already in place

.

I'd call anything under about 8 cents/KWH cheap, anything under 5 VERY cheap, anything 3 or under VERY VERY cheap.

 US average is over 10 and has been for a while, but I've not checked in the last couple years so it might be more like 11-13 range for 'average' by now.

 Other countries are all over the map, and any large country and even most medium-sized ones have regional/locality variations.


 Hawaii, for example, has some of the highest rates in the world - has to import everything it runs it's generators with, and apparently it's cheaper to import oil (even at last year's pricing) than trying to import anything else (oil tankers can carry a lot more energy content per ton displacement, keeps SHIPPING costs low).

 Chelan and Douglass County PUCs in Central Washington, on the other hand, have under 3 cent/kwh rated due to multiple large hydro projects EACH on the Columbia river, and subsidise their local rates some by selling lots of their cheap excess-to-local-needs power at quite a bit higher pricing to SeaTac area and other Washington utility company(ies).
 Grant County PUC next to the other 2 is under 5 cents for similar reasons, but only has 1 or 2 major dams to work with so can't subsidise local usage as much.

Multiple threads reporting this thing as a SCAM.

 Please don't start new ones.


 P.S. Paypal is in and of itself a SCAM by design, don't trust them. Way too many folks (I am one of them) that have been RIPPED OFF BY PAYPAL.

 By spec, if the PWM line is not connected the fan goes to 100% - has nothing to do with the controller.

 Personally, I don't see the point of running the fans at less than max - keeps the unit cooler for better longevity - but noise isn't an issue for me.


 By multiple reports, there ARE PWM fans out there that do NOT follow the spec, be sure to check your fans before you trust them to go 100% with no input to the PWM line.

 And they'd still be semi-morons, since the peak was a good bit below that point.

 There was NO REAL NEWS, no way Bitcoin was going to exceed it's previous peak.

 The halfing pump won't be 'till probably at least April, more likely May-June timeframe next year.
 THAT one will have a solid reason behind it, and I expect pricing to stay a good bit higher after the pump speculators die out.

 Will it get back below $300? I'd say "definitely, probably by end of month".
 Will it get back under $250? I'd say "probably, but not certain as so many folks bought it and probably plan to hold for the NEXT spike to sell".
 Will it get back under $230? I'd say "probably not, unless some major anti-Bitcoin news shows up".

I doubt that Bitmain will produce another water-cooled product - uness BitFury starts selling such a product to the public at some future point.

 Probability VERY VERY low.

There will probably be a jump in Bitcoin pricing a month or so before the halfing, but it will then recede some (likely retaining SOME of the bump) a month or two afterwards.

 I don't anticipate it doubling (though it wouldn't shock me), more like a 60-70% peak jump I'm guessing, then back down to 30-50% higher than pre-bump as a "stable" price over time.



 ALL predictions are speculation though, and many things can happen to make even GOOD speculation look bad in 20/20 hindsight.

The spike is looking to be rather short, and was way too small to affect trying to mine SHA256 coins with GPUs - we would have needed a spike into the MILLIONS PER BITCOIN to even get back into the ballpark.

 It WAS a nice bump to profits for those of us already mining profitable with ASIC machines, and might have gotten a few folks with older no-longer-profitable ASIC machines to manage a few extra $ profit out of some of those.

 It's going to be unfortunate for some folks that bought miners during the spike because they were convinced it was a lasting price change, but when the Bitcoin price goes back down under $300 they won't RoI their new hardware. Good for the manufacturers though.

I'm betting Bitcoin price will be back to the $250 range before the end of the year, possibly by the end of November.

 There was NO SOLID NEWS OR REASON for the spike in the first place, I'm still a bit supprised it got as high as it did before reality finally reasserted itself.

 Enough folks bought in that I kinda doubt we'll see $230 as a consistant price again, though.

The speculators ran out.

There was no real SOLID news or reason backing the sudden price increase, sanity is now returning and we probably will see $250 again before the end of the year, as I've been predicting for a while now.

 I don't think we'll see $230 again though, pretty sure the price will settle in a LITTLE higher.


 $10 price variations are small, not worthy of consideration. Pretty much the "noise level" on the price.


 Only morons were predicting $1200 on this spike.

There is no such thing as a "quiet" high flow fan, to get to the range of CFM they need to achieve decent cooling they HAVE to go with a fan that makes quite a bit of noise.

 TANSTAAFL.

It's now lower, but if B5 was still available it would ALSO be lower.

 Probably.

 Not really fair to compare a product that is currently "out of stock" (possible short-term for price adjustment) to one that looks like it will never come back anyway.

The V3 PACMIC investment was competative with the B-Eleven one, from what I can tell of the latter.
The V4 PACMIC investment is a sad pathetic joke and I don't understand why anyone is putting their bitcoin into it.

Weren't they talking about "by December" or "by end of December" for when they planned on the miners being available / hashing starting?

Solar cells degrade over time though - but IIRC they commonly don't lose more than a couple percent of their capasity a year.
20 years seems to be a common "write-off" timeframe for them, but that might be fueled in part by increasing efficiency as the technology gets better.
