Can someone tell me what BTC/USD exchange rate Cex.io uses to calculate it's $0.26c per GHS monthly maintenance fee?

Not a great price. It should be lower. Need to wait for second batch.
Hope you guys checked the ROI after 15days.
Depends where you live, if you have cheap electricity you might make ROI. I won't not at 30cents per kWh.
When it ships on July 10th. the diff will be around 20bill, and there is probably at least half a dozen more diff increases before you get your 0.75BTC back, so your profit ends up being mostly in the resale value of the S3 in 4mths time.

Ordering will be up shortly it appears, but shipping starts on the 10th of July.
That will mean after the next difficulty increase.

64  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 30, 2014, 08:18:31 AM
Yeah:)

Got it. S3 is by Bitmain Smiley Sold and shipped by someone else...

Never mind.
I would be surprised if the price that is being quoted is anything like the real S3 price. They are probably quoting high to make money of suckers and cover themselves.


65  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 30, 2014, 06:17:24 AM


BTC just BROKE $600... Grin

Time for BitMain to break the silence ...

ZiG

Even a post to say what they were up to without disclosing prices would be nice, just so we have an eta update that's all.


On a side note, I would imaging that the GHS price on Cex.io will take a hit at people cash out of GHS to get some BTC for the S3.

I got my X-1 and it has been up and hashing for the past 60 odd hours.
From BA or Minersource?

Yea right the jpeg is getting larger
Nothing that adblock can't handle, if not the ignore button works wonders with jpeg posters.


The suspense on the S3 pricing is killing me!

I like Kuwait-1c/kwh, but the source is from 1966(??).

Not sure if Bitmain would have a lot of clients in Kuwait, who knows. Maybe it could be a good place for mining farms.

Not all of us live in China with subsidized electricity prices.
I live in northern europe and we have 0,12$ residential without any subsidies.
i pay 0,08$ as i got a 1man company registered and get commercial pricing.

There is a lot of variation depending on where you live. Just have a scan of this list:


http://en.wikipedia.org/wiki/Electricity_prices


For example, most of the EU, which represents about 500million people, is over $0.20c per kWh.

With the diff increase that's just happened (16.8bill), the 0.26 per GHS monthly maintenance fee on Cex.io represents about 48% of your mining income.

Are they not going to try and get this down with more power efficient hardware? People will start to leave and buy mining hardware again.




People are too stupid to leave.


You are probably right.
I would imagine that a lot of people are incapable of setting up their own mining farm, so any revenue is better than none.

My main gripe with the OP is Bitmain assumes $0.12 per KWH when doing their ROI calculations. For people like me who have to pay $0.29 per kWh and rising this week by another 14%, it's kind of a joke to see $0.12 used as the median electricity price.


Someone should start a poll to see the real price people are paying. Perhaps Bitmain could add power cost as a profile field on their shopping cart.

Not all of us live in China with subsidized electricity prices.


I think a large part of the US falls within the 0.10-0.15 range, it's not just China. At 0.29 you should consider hosting options. Adjusting ROI calculation won't do you any good, just think about that.
Quite true, buying GHS on cex.io with their huge fees, is more profitable atm than my Antminers, I understand that. Haven't looked into hosting options yet, buy I will make a point of doing so now that you have reminded me of it.

Basically, from simple maths, 1 CX750 can run a 180GH/s S1 and a 500GH/s S3 with no problem?

S1 normal speed <--- 360W
S3 normal speed <--- 390W

360+390=750

Did I do anything wrong here?

You math is correct. But in practical case you need to allow some free room in between the power supply output and power consumption.
There 360 and 390 are rated power consumption from the manual and they can be lower or higher slightly for each device.
So, I will advice you not to load one S3 and one S1 in to a 750 Supply.
Most probably you may need to undervold and downclock your S1 in 2 months and that will make you run if S3 is not overclocked.
Better take a decision after you secure the S1 and S3 if you already bought the 750 Power Supply Unit.
Else buy a Dell Server PSU and mode it or buy an already moded server psu. Better stick to 1000W or above.

Cool! I got the cx750 for my s1 already. Probs under lock once I get my hands on an s3.

Be very careful, it's not the total power consumption that's the issue, it's how much current each 12volt circuit can deliver. Read the numbers on the power supply and understand what each connector can actually safely supply, or you risk a meltdown.


75  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 27, 2014, 05:29:17 AM


I am not arguing with you but, @ 500GHs these units will net you $18/day and assuming another 25% diff increase $14/day.  After that, assuming continued 25% diff increases (which I do not expect) it would get very ugly.
No they wont, at current 504GH/s will only gross $11.01/day that's assuming zero power cost and zero pool fees! Net of course is substantially less than that.

Mine also has 1418 as well so I am guessing this is another marking not in regards to build date.  I couldn't get it to grab the text with just my phone and didn't have another camera to bust out to take the pic.
2014, 18th. week  sounds about right. Late April early May.

77  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 27, 2014, 04:30:49 AM

No, hardware proliferation caused the diff. (number of hardware units).

Hash power improvement in a single unit/chip can't keep up the diff. rise caused by this proliferation.

Long term, mining bitcoin will be like selling chewing gum. You'll have to work pretty hard to get almost nothing.


The number of hardware units mining BTC has decreased over time. There are far fewer people with ASIC hardware than CPU and GPU owners which were the mainstay of BTC mining for years. People just use to walk up to an existing PC, install some software and start mining, can't get much easier or widespread than that. What has increased is the hash power from the introduction of ASICs last year. The mining is concentrating, fewer people mining BTC, focused on buying larger and larger units, chewing more and more energy to get less BTC daily than the did a year ago. The majority of miners have moved onto other coins they can still mine profitably with CPU and GPUs. I mined my first 6 BTC on a HD 5770 GPU I literally got out of the trash can. Now I have several antminers and I am not sure that any have paid for themselves yet, as Bitmain's modelling is based on too low an electricity price. Before I jump into the S3 I am going to do the ROI modelling very carefully.




78  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 27, 2014, 02:51:47 AM
Hash power improvement on hardware can't keep up with the diff.

As someone said above, no ROI, no care. And it looks like it will be the case.

Hash power improvement causes the diff. People think more hash is better and get proved wrong every diff rise.

What you need to aim for is the most BTC per kWh. but that doesn't fit the more hash is better mindset.

How come it says cex.io trading fee will be: 0.75%? cex.io fee is 0.2% usually.

Actually, that workaround is probably no longer needed...

If anyone wants to test this prerelease version (intentionally NOT flagged as "latest") I'd appreciate it:

https://github.com/kuzetsa/gekko/releases/tag/microtrade

I've had it running for a few minutes, but other people are probably using different settings than mine so it'd be good to have more than one tester.

Testing. Is there any way to log the trades to a file? Currently it's just displaying on the console.


look in the "bin" subfolder at the shell scripts (not sure if you're using linux or not) for inspiration...

note that there is a windows port of the "tee" command available here:

http://gnuwin32.sourceforge.net/packages/coreutils.htm

alternatively, using the 100% microsoft-provided windows powershell "tee-object"
(tee-object even has similar syntax and can be abbreviated "tee" but requires using powershell)

http://technet.microsoft.com/en-us/library/hh849937.aspx

I am using linux, I looked at the 4 scripts in the bin folder but they seem to assume there are log files in the log directory. Mine is empty all I get is console messages and no saved logs at all. I have the adviceLogger enabled. I see the launch script with the tee command is that the only method?
