It's totally fine by me to have the ROI discussion in another thread.

I ordered from Spondoolies and I will most likely do it again soon.
However, the tone of discussion here (I don't mean Spondoolies staff-you guys were great) with respect to opposing views is sometimes jarring.
After all, we are here to make sure (in a small way, perhaps) that bitcoin succeeds-at least I am.

That said-re chinese market. Guy, care to elaborate-you understand their marketing or price trends or whether they will develop 20nm or jump straight to 16nm?

Watch out boys, only approved comments are allowed in this so called 'self-moderated' SPT thread. I think we need a new thread just for Spondooles ROI discussions.

Although this thread is self-moderated, we don't delete comments. This thread should be kept for hardware related questions, per the subject. The mods are enforcing it, without our request, but with our consent.
You're welcome to do ROI discussions elsewhere.

Guy

I beg your pardon, but the title of your thread is:...."Best $/GH/s ratio", so I am not exactly sure how this is not related to ROI.
Edit: OK, if not ROI, then it is definitely a comparison with what? Other machines?

A quick google search shows "Provasic" as a fictional drug from the movie The Fugitive. I think we are being trolled here.

...and "bit" is now 100 satoshi AND a unit of information AND "a piece"

There are not enough words to uniquely describe the realm anymore.
My point is that this by itself means nothing, but thanks for pointing out the connection. I knew that the word seemed vaguely familiar.

I can't see the miner's profitability effecting the price other than maybe some miners may consider buying coins instead of hardware.  There are a lot of Bitcoin users who have never even owned a miner.

Interesting...the analogy would be that you think that the price of gold is unaffected by how much it costs to mine it?

Edit: As was proposed by Y. Guo (per my recollection), every bitcoin owner should also mine. This way, you have a vote on Bitcoin value, etc. If you don't mine-you relinquish this responsibility to someone else who takes it.

As of right now, for every 100BTC owned, you need to mine with 590GH only (almost exactly three antminers S1), everything more is an excess.
calculation: (0.59TH/125000TH)X21000000btc=~100 BTC or ~1Th for each 150 BTC owned. These are, of course, minimal numbers that will increase as speed will be increasing.
9665  Bitcoin / Mining speculation / Re: How many S3 are you planning to buy? on: June 24, 2014, 12:59:28 AM
Sounds like Bitmain is dropping the s2 form factor AKA "The Last Batch" on their forum thread, so I will look elsewhere for a unit that can sit in a rack . The S2 was a GREAT product, I wish they would have stuck with the development of it ..
I am thinking the price of the S3 will be priced below the price per GH of the S2 and that is why they held up 1 week on releasing the S3 till they could get rid of all the S2 inventory.


you think itll be lower lower than the $1.45/GH after coupon price or $1.85/GH before coupon price?

you still have to use a power supply for S3, so should be slightly less.

I think that miners have to focus like a laser on what's the most important-highest ROI and drive manufacturers to provide one through the power of our purse (don't get on on sucky deals). If it is a hobby (and I respect this very much), then every new hardware is exciting as well.

9667  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 23, 2014, 10:50:05 PM
They pushed back their shipping date of the S2's after people ordered

what do you mean-it is still June 26, isn't it?

When I and several others ordered, the ship date was June 23rd

I see...thanks

I had no problem with the spondoolies ROI estimates being here, but take a look at the direction that whole discussion was taking and it clearly had nothing to do with hardware by the end with name calling and what not. In the interest of not just deleting posts the discussion was kept together as best as the forum system allows. Note, no post was deleted or censored. The hardware subsection is meant to be mostly dry technical discussion as per the rules outlined here https://bitcointalk.org/index.php?topic=139380.0 and yes it's very hard to maintain that standard throughout the section but usually once someone starts complaining that's when we're even aware there is an issue on a thread.

Thanks for your thoughtful reply.

Considering that most people interested in mining and considering a hardware purchase will probably read the threads in this section of the forum and likely miss discussions in the speculation section, would you agree that it is fair to allow non-abusive discussion of SP30 ROI in this thread in order to maintain a balanced discussion ?
Remember this is the hardware section for mostly technical discussion and announcements, BUT we are usually quite liberal with allowing discussion to wander, especially if the opening poster is happy for the discussion to veer off in that direction but it's very easy to suddenly find yourself in a discussion debating the ROI equation of some totally unrelated hardware like the Neptune when that happens. We usually don't intervene in self moderated threads since that defeats the purpose of self moderation unless there is open abuse or spam. The topic that caused the split degraded into the former.

I'm very happy to see discussions of the likelihood of recouping costs since I hate to see people throw their money away thinking they're buying some money making unicorn machine that will make them rich and that never happens. My personal view is you will never ever be able to buy hardware again that earns more than it cost you, meaning the only way to make money with mining hardware is to buy it, mine with it for a while and then sell it while it's still worth something, and avoid preorders like the plague. There was one preorder in the history of bitcoin ASIC mining that made an absolutely embarrassing killing profit for those who got it first and it tainted how people have thrown their money at manufacturers and scammers since, even though the conditions for that same thing happening will never ever happen again unless we can make quantum computers.

Thanks for a great, but disconcerting comment. It rings true, but many people (including myself) cannot believe it yet (guilty of preordering SP-30 even after the KnC debacle).

Would you please explain why SP30 ROI estimates are off-topic here ? I'm having a hard time understanding the rules here.

yes, since this hardware will not materialize for a month, hence no hardware to discuss. Are you mothballing this thread?

Have anybody tried regular Beaglebone black, rev B or C together with bitmain microSD card to control S2?
Did it work?
9672  Economy / Speculation / Re: Following: a great week or two to buy BTC on: June 23, 2014, 05:02:53 PM
The top reason to drop right now would be traders selling out on a break of trend. There are a lot traders just front running the next 'scheduled 9 month bubble' which might not happen.

A much simpler explanation is that hedge funds or other funds that are interested in buying into the auction are employing traders to push the price down so they could bid lower.
They do it all the time on a regular stock market (push down before buying en masse). That was described brilliantly by Jesse Livermore, who was always testing the downside of the market before buying a larger block. Read "Reminiscences of a stock operator"-a classic.
9673  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 22, 2014, 10:15:53 PM

you mean that 4pin to 6pin adapter cannot handle 390/4=95.5W? There are 4 PCIE connectors per each S3 unit. There are 2 PCIe connectors and 2X4pin connectors per each CX500M.

Not sure where you're getting the 4 from, as only 1 pin will be delivering the power, so on a dual molex to 6pin pcie adapter, it will be 195w/16.25A per board, and 65w/5.416A per PCIe pin, but on the molex side 1 12v pin will be pulling 130w/10.83A.

Get them cheap and use 2 adapters per board to split it out if possible.

Or do what Xer0 said below Smiley.

At least you won't have "wasted"/unused wattage per psu, as you can share the current between psu's.

OK, thanks
9674  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 22, 2014, 09:52:39 PM
Could someone please advise, i use a corsair cx500 on current s1 and never a glitch, i notice that there are 2 spare molex 4 pin connectors on psu,  i can buy adapter for these on ebay to convert molex to pci-e , so my question is would this work with the the s3 (total 12v output from psu is max 456w) for the two othe pci-e on the boards.  Afterall its only another 30 watts more?

One S3 at clock speed can be safely run on your PSU.  Molex to pci-e will do the job.

re the same: can one 4-pin molex power 6pin PCIe or you have to have two dual male 4-pin connectors converging on a single 6-pin PCIe?
I see that there are both types for sale on ebay.

It will be dual 4pin Molex to 6 pin PCIe, trying to shove that much power through 1 12v line will only end up in heat, fire, then tears.

Like this.

9675  Bitcoin / Hardware / Re: Two Antminer S1 on One PSU on: June 22, 2014, 09:49:12 PM
I consider underclocking / undervolting my antminers. This should enable two antminers to run on one PSU. Problem is that my PSUs only have two PCI-E connectors.

May I use some of the other connectors? Can I cut off the end of the CPU connector and connect three of the yellow cables and three of the black cables to the corresponding slots on the miners?  

as per S3 message board, you can connect molex (4 pin connectors) through 4 pin to 6 pin adapters to PCIe slots.
I have never done this so far, but plan to try with S3 9 I also have CX500M which have only 2 PCIe connectors.
S1 undervolted should be just 200W, right?

This shit is crazy.... It really looks like they are mining with our machines RIGHT NOW.
I can think of no other way that hashpower could possibly magically appear

Looks like a BFL replay...   https://bitcointalk.org/index.php?topic=659828.0
The drama of it all....  Holy Swashbucklers.


Kudos to the folks at blockchain.info for putting all that together and figuring out who was who. They've always been mining but they would show up as the Known Other which was close to 40% before they broke it out out recently. So, what it doesn't show is the hashrate that KnC might be using on those other pools if they are using that. However, considering how greedy those bastards are they probably don't want to share anything with some lowly pool. They have no image to protect nor do they care either.

KnC came from the banking industry and they behave like a bank with all that small print, email offers, etc.
For a bank your deposit is a liability (it is called that-surprisingly). Bank uses the deposit sum to make loans that are a multiple of your deposit, or buy 10Xtreasuries=40% per year for them. Same for KnC-your orders are KnC liabilities, so they use your preorder cash and order a multiple of Neptunes (chips), then they give you back as little as possible, while using the rest for themselves and by doing so, undermine your profit. Nice business model if you can maintain it-but you just CAN'T.

I hope that Guy will get some good news in Eastern asia. There is a noticeable drop of posting/enthusiasm here, no doubt because of the crazy ASIC deployment in the last few days.

Additionally.. I believe there's a ton of fiat moving to be ready to pounce after the auction... some of mine included. Time will tell... its gonna be fun to watch.

AFTER? You don't know how Wall Street operates. They will pop the price 20-30% afterwards and you will be caught chasing it. Have you seen any decent IPO?
9680  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: June 22, 2014, 03:27:01 PM
A realistic  power ability for me is 2k-watts summer 4k watts winter.  

It is funny that I came up with exactly the same power ability.

At one point in the last two weeks I got to 3.1kw, and it was very difficult to cool the room and the house (also my electric utility told me that I am going to pay a lot this mo  Wink), considering that it is 92-100oF EVERY day now, so I sold off to ~2kw and will stay at this level until late fall and winter.
