When is the last sale made from bitfury to the general public?
About 6 weeks ago last I checked



Bitfury sold gear 6 weeks ago?  Where?  To who?  A retail consumer/small miner?  I'm not being facetious, I would like to know.

For those who have mined with BAN before. What is the longest run you've seen without finding a block?
This is it.

someones dumping an SP20 farm in the states on ebay for 419$ a pop, free shipping.
sure, they're used, but......
they work I purchased 1 piece of it.  my offer was 409 he took it. I got 4% ebay discount net was 393
Ditto. Just picked one up for delivery ~Feb 3rd.
What's the 4% ebay discount?
384  Bitcoin / Hardware / Re: Modify S5 Antminer to watercooling on: January 26, 2015, 03:32:41 AM
So I am confused.  Is Bitmain on board with this or do we have to lobby them to sell us what we need?
As Dogie said,it is unofficial on Bitmain now,but we could provide water-cooled S5 sale,price is $18 more expensive than official price of air-cooled S5.In addition,because we purchase boards from Bitmain,amounts couldn't be too small,if you want to purchase water-cooled S5,amouts of each order is 3 at least.You could send email to  watercooling@ysun.net   for purchasing,and preparing time of arranging shipment is about 1 week.

But to fill out the case you show in the OP you would need the equivelent of 4x S5's correct?

Interesting observation related to
http://en.wikipedia.org/wiki/Active_noise_control

i have three Sp20 and one S5 in the same room with S5 running with Noctua and Scythe ultra kaze fans (push pull).
I suddenly realized that i have much less noise in comparison when I had just two Sp20 and one S5.
Upon measurement, approximately same amount of noise is coming from each Sp20 at ~69dB and a little less (maybe 64db from S5 with two fans) with all measurements at 1 ft.
However, at the door, just four feet away, the noise already drops to just 61 dB, which is a much faster drop comparing with a single machine.
My point is that most likely some of these miners produce the "anti-noise" (see article).
I set up (accidentally) my three Sp20 in such a way that one is at fan 10 (fixed), one at fan 6 and one at fan 14 (these two on auto).

Right now with all four miners running, I have just 51dB ten feet away and can barely hear them- a great improvement.
My point is that by having multiple machines at the different fan speeds they might produce a canceling anti-noise and the whole setup would be less loud (at least this seemed to happen in my case).

My dog has ability to move and see at ultra high speed (at nearly 150 FPS). Thats my conclusion after witness him doge a light spark from my fireworks by bending down and lick his balls.

Anything wrong with my conclusion? Should i test this with a Glock?


PS. you didnt understand jack about sound wave let alone calling something "Active Noise Cancellation". Go to a Cinema, buy all the seats then start experiment listening at every seat.....
Just another confirmation of my theory regarding the correlation between low trust scores and commentary that deserves to be ignored.

Unfortunately it's a cycle that is self perpetuating.  Payments are delayed, for whatever reason.  Then people stop mining the pool because they are not getting paid.  That makes it harder to find blocks to catch up for those owed from previous days.
I stick with BAN when I can.  But my miners are hosted at three locations and I get bills throughout the month.  So I don't like to go more than a day or so without getting paid.
I will say the pool has always paid it's debts and I know of no one who was short changed.  But unlike other pools, consistency in payments is not their thing.

Anyone having trouble on Centerus today?  My miners went down last night and I am getting no response to calls or emails.
Just wondering if I was the only one.
389  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: January 23, 2015, 04:57:52 PM
The $0.47 per GH is what you pay for the contract, the $0.0015 per GH is what you pay for the maintenance.

Some more figures
5,000TH, costs BTC10.08540406 and makes BTC0.02499871 per day
Which means if difficulty never rises again you are looking at 403 days until breakeven is reached.

IMHO Cloud mining has a place in the market.  There are plenty of folks that want the experience (detached as it is) of mining btc.
But for all kinds of reasons they can not, will not go buy a miner.  Cloud mining is the only way they can reasonably share in the experience.
But every cloud miner needs to know - you will never, ever, ever make money cloud mining.  At least not anymore.
I rent my miners out everyday.  They rent for more than it costs to buy the btc from coinbase.  The people I rent to will never make money from renting my rigs. 

I am not bashing cloud mining companies or cloud miners.  I'm just saying don't ever expect a return on your money.  The only reason anyone starts a cloud mining business or rents out their miners is because they can make more money than just running their rigs on their pool.  So yes - you will pay more to cloud mine than the btc you mine is worth.  Just be aware.

Don't want to post anything negative on the auction so I'll post it here.
I just don't see that buying a Prisma today makes sense.  They just are not efficient enough.
Unless you have 22kw of psu's sitting around and power under $.08/kwh.  Even then you are looking at 90 days ROI assuming diff is held to a 5% gain (I know it's going down slightly in a few days).
There certainly are folks who have that going on.  I guess I am just warning noobs.  Do the calculations on this before bidding...as always.

On the positive side - I did have to return some v1's and I'm sure these are much better.  But I have 4 v1's that run like champs.

lol you guys keep making fools of yourself by calling difficulty every time dont you?

I swear i can make better prediction by just flipping a coin.

3.5%  vs -2.5%  .....so close.



Some one should do a study to verify there is a correlation between trust level and rude, inflammatory, adolescent forum member posts.
392  Bitcoin / Pools / Re: [BitAffNet] How we're the #1 Bitcoin Mining Pool In The World (proof inside) on: January 21, 2015, 07:11:04 PM
hit another block.

has anyone been getting doge or nmc ?

My doge are now over 700.

Yes.  5700 doge.  But it's not worth much.
393  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: January 21, 2015, 04:51:20 PM
Is there any software I can use to monitor all my 6x SP20's which are remote?  Other than going into them individually via ssh?
394  Bitcoin / Hardware / Re: Modify S5 Antminer to watercooling on: January 21, 2015, 04:46:25 PM
How much are the S5 hashing boards and how do you go about ordering?
395  Bitcoin / Pools / Re: [BitAffNet] How we're the #1 Bitcoin Mining Pool In The World (proof inside) on: January 21, 2015, 04:33:53 PM


I received my payment in full (which the pool has always paid) a couple of hours ago. Good Luck

This bitch is still waiting for payment. 
I choose each miner's difficulty setting using a random number generator on my iphone and it works better than any of yours.
396  Bitcoin / Pools / Re: [BitAffNet] How we're the #1 Bitcoin Mining Pool In The World (proof inside) on: January 19, 2015, 08:24:57 AM
I don't know what you are looking for but your speeds are above average. The 457 is a little low if it's an S3+. But the rest are great.
397  Bitcoin / Hardware / Re: ASICMiner BE300S Samples Arrived, <0.2W/G Achieved at Board Level on: January 19, 2015, 02:36:13 AM
Hey Icebreaker, please leave. Nobody wants you here if you're not going to be polite.

He's mostly mentioning because the single-chip data was posted last year and the prototype string board was already being tested at that time. Basically it's a commentary on how inept ASICMiner's PR/communications can be, more than any questioning of their technical competence or engineering efficiency.
If no one talks to him, he goes away. Just like grade school.
398  Economy / Service Discussion / Re: Cointerra is dead on: January 17, 2015, 06:42:59 PM

Personally I think what cointerra did was shady as crap to the C7...  The knew they weren't going to pay, and let the DC provide them power for 2 months for free and collect profits.

there's two sides to every story.  I'm sure we will hear more about this.

Suppose he supports bfl as well hey! Jump off a cliff and die youth!
If only I had listened to you all these years.
Another for my ignore button. Two in one week. That's a pr.
399  Bitcoin / Hardware / Re: S-5 review. It has arrived some info is in! on: January 16, 2015, 08:09:11 PM
What is the hash rate, and is noise really so loud?
No. Noise is quiet.
400  Bitcoin / Mining speculation / Re: Jan 12th to Approx Jan 27th diff thread (3.5%) on: January 16, 2015, 03:41:17 PM
Assuming the price holds I think we'll see the S3's and all miners released prior to their introduction slowly get turned off.
Does anyone know if BitFury has their new chip up mining?  They said it would be released around now but I don't think it's actually up in mass yet.
