... If it is, I will tell you what it is called - after I have cleared out their inventory  Smiley.

So you are not going to tell us? Cheesy Is it a preorder or has your friend hands on it?

I will tell you but if I put a link here now I'll never get a chance to buy one.  He is going to let me know if it works and I bet they will get some more orders if it does.  After that,  I will post it here.  Don't want to spoil it for him.

Don't post the link here. The miner is fake, the company is a scam, and your "friend" is most likely trying to con you out of your money.

I have to agree with OgNasty. If the company and it's product must remain "secret" for it to be viable, then it almost certainly is a fraud/scam/fake/whatever. Anybody with a legitimate product will open their product to some kind of scrutiny. Folks that want to operate in the "dark" do so for a reason, almost never a good one.

So is your "all in" price about $200 to "muffle" one S7? Have you down clocked in any way, or is it running at stock speed from the factory?

My $.02:

I think anybody who assumes a low difficulty rate increase going forward is deluding themselves. While the last 6 months have only been about 25% (for just 6 months), the last 12 months is more like 100% growth in difficulty. I think the golden summer is drawing to a close. I too think it's silly to make predictions about BTC price, but I am confident that BTC difficulty will continue to rise. Perhaps more slowly than a year ago, but still at a breathtaking rate compared to any other industry.

In terms of SP50 pricing, Bitmain has provided a lot of "cover" for Spondoolies. Just given an equivalent $$$/TH, Spondoolies could price the SP50 at $40,000 and still be undercutting the S7 (which needs a PSU). The SP50 has better efficiency and better operational deployment for the "Professional Miner" (extracted from their announcement). I have no idea what it costs to manufacture an SP50, I doubt it shows up for less than $40K.

Nice and speculative for me, since either is a nogo personally.
844  Bitcoin / Hardware / Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH on: September 23, 2015, 07:25:28 PM
with spondoolies back in the game, i hope to see a price war again  Grin . in my opinion the s-7 price was an insult. i've got free electricity and still did not like the numbers for roi.. this is a game changer for the best

I wouldn't get my hopes up on this. I expect Spondoolies will price their SP50 to look reasonable in terms a comparison to the S7. I don't think they will try and undercut the S7 hardly at all. Considering they have an efficiency advantage, they may well price above a commensurate number of S7's.

Unless and until we see a price and ship date, this is by no means "a game changer" (IMHO).

I tested a bunch of different settings; I recommend:

Fan %    Freq     Watts     TH/s     Error %
 30         612      1237     4.85      0.025

Measured 76 dB at 30% fan speed; surprisingly quiet.
These run about 5C cooler than an S5+ 1/3 with the same power consumption.
This allows you to run the fan at a lower speed.

I used an EVGA 1300 G2 PSU so you should get slightly better w/GH with a server PSU.

0.255 w/GH with a Gold PSU  Cool

Could you double check the frequency? Looks like a possible typo?

In case folks haven't seen it, Spondoolies has decided to return fire at Bitmain, with their 100+ TH SP50 monster. Looks to me like the ASIC arms race will resume. No date or price yet on shipment, so I think this adjustment will not reflect any SP50's. Eventually they will show up and push difficulty to new heights.
847  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: September 23, 2015, 05:26:32 PM
I wonder if Spondoolies expects the SP50 to dismantled a bit as part of installation? It would be obvious to remove the power supplies before installing it. I wonder if they expect the blades to be removed and only the chassis to get installed in a rack.

All interesting questions to be answered. As with most other folks I can only hope they eventually make a small ASIC count "home miner" using the PickAxe. That might be a lot to wish for.

Congratulations on producing the largest miner known to man.....
848  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: September 23, 2015, 05:20:52 PM
sidehack needs to get some of these chips.. 137GH stick miner chip would be nuts.. prob not even possible with USB power

While I probably shouldn't speak for sidehack, I'd be stunned if he was interested at all. I think you can expect the PickAxe ASIC to be a high wattage, BGA monster compared to the Bitmain chips he worked with. We'll need more details, but I think it's safe to say it wouldn't be USB powered.
849  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: September 23, 2015, 05:15:04 PM
I want to drop one of these in my basement, if anything just because I can.. My wife would get a kick out of that fan noise Smiley

I hope your wife is a weight lifter. Maybe she can help you carry it down the stairs. It must weigh in excess of 100 pounds.

850  Bitcoin / Hardware / Re: NEW SPONDOOLIES SP50!!! on: September 23, 2015, 05:10:51 PM
I will try to buy some.  This decreases the amount of wiring and work to setup, so its a labor saving for me.

Better have some help lined up for when it arrives. It must weigh in excess of 100 pounds. Of course maybe you just tote around 50Kg objects all the time.....  Smiley

Personally I am just happy to have Spondoolies "surface" again and resume communication. Clearly they didn't say the right words or prepare the right kind of PowerPoint slide to extract $116M from the VC guys in California. Probably not the worst thing that could happen to them (IMHO).
852  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: September 22, 2015, 11:19:49 PM
@Zvisha: thanks for you Spondoolies work-awesome job, man.
Since you are not directly involved with Spondoolies any more-what is your take on 21co bitcoin device?
Interesting or meh?

yeah id be curious to know his take as well.  seems after all his hard work and what hes done with spondoolies he could give some good insight

He may well still have some financial interests in the BTCS merger, even if he isn't employed full time there. We shouldn't be surprised if he doesn't respond.
853  Bitcoin / Mining / Re: Increasing Zero towards unreachable difficulty ? on: September 22, 2015, 11:06:36 PM
I'm not sure pointing to altcoins - the majority of which that have failed have been mine-it-for-all-its-worth-then-dump-it - makes for a strong anecdotal case, but in terms of Bitcoin your argument seems to lean mostly on the reward halving causing a mass exodus of miners to the point where block intervals are sufficiently long that additional miners also lose interest.  Fair enough.  I still don't think that makes it unreachable/impossible to mine/etc; OP's original argument was that things would effectively be permanently stuck.  Whether or not it kills off a coin as a viable [insert marketing term du jour] is another matter.  We'll find out the answer to that soon enough Smiley

While it's an interesting argument/possibility, I think it's a VERY remote possibility. Just look at bitcoinwisdom as a an example. If it were to start showing a decline of say -20% estimate for the next adjustment, there is a lot of mining gear that would get turned right back on. I think that for many miners, when it gear gets unprofitable, it goes idle. It doesn't get destroyed immediately. If it gets sold to somebody, they didn't buy it so they could destroy it, they bought it to mine with it. I think the actual decline of mining capacity will happen slowly (i.e. weeks and months). I think it's more likely that some miners will attempt to sell their gear in anticipation of the halving, because they expect a major decline in the resale value.

There are so many ways to look at the halving, it's crazy to get an accurate guess of what will happen.
854  Bitcoin / Mining speculation / Re: Mining Profitable? on: September 22, 2015, 10:23:01 PM
A big chunk of "Mining Profitability" these days is related to when you sell the miner (i.e. asset) and the resale value at that time. You may well not "Break Even" (aka ROI) until you actually sell it. I am certain that the S7 will need to be sold in order to generate any actual profit for most folks. As to when that happens, it all depends on your situation, and what's happen in general (e.g. difficulty, BTC price, new miners, etc). The S7 probably set a new record for how long it held it's value in terms of price. It never got priced real high, and difficulty and BTC price remained fairly stable for months. I don't think you can expect the same for the S7.

Do you agree with me that difficulty will have an effect on it?  I mean if low difficulty... you don't have to sell for long time.   If high difficulty changes less time with miner and it get's sold sooner.


I'm just still trying to understand how difficulty is overestimated from earlier in thread.

Part of it may have to do with how folks express a difficulty change. I'd swear I saw 3%/month, which is really pretty low, and way lower than 3%/adjustment (i.e less than 2 weeks). Folks that have been mining for more than a year consider 1%/month to be a SMALL change. In virtually any other industry, 1%/Month would be HUGE.
855  Bitcoin / Mining speculation / Re: Diff thread sept 17th. to sept 30th Picks are open!! on: September 22, 2015, 10:16:42 PM
I'll take +1.76% to +2.00%

I think we safely ignore the $400 21Inc Juggernaut until around Thanksgiving (US Holiday in late November). Of course we don't know what 21Inc is actually in terms of deploying miners within it's own walls. Probably something a lot more substantial than what they are sell for Pre-Order now.

.......

As usual, you are very well informed, Guy!  Wink

To be fair, with 0.16 J/GH this would be the most efficient chip in the wild so far.
The 0.6V BM1384 value is just quadratic extrapolations of the 0.66V value. Try it, it fits perfectly. IMHO too perfect for a measured value.

Anyway, 21 really screwed it up with the GH/mm2 value. In best case they have here about 2 GH/mm2 (for sure not with 0.16 J/GH). This is a good GH/mm2 value for 28nm, but for 22nm it should be 3 ... 4 GH/mm2. Otherwise this chip will be simply too expensive in production to be competitive for standard miners.



You have got to stop thinking about conventional economics here. The IoT bandwagon is impervious to conventional economic considerations. After all, folks are going to just be so happy to pay an extra $25 for their light bulb, it doesn't matter if the ASIC price is a little high. The fact that it's going to be part of the IoT relieves it from those pesky metrics.

If it's connected to the Internet, it MUST be great!!!  Smiley Smiley Smiley

I also found the "WiFi connected Garbage Cans" to be truly hilarious. In my house, the garbage goes out when it stinks too much, or it's pickup day. I would love to see what a "WiFi can will cost" and how it changes the need for the trash hauler to drive down the street on Monday morning. I am absolutely not interested in doing Tech Support at my house for any new Internet connected Gadgets. If you aren't married, this may work great for you. My wife will have nothing to do with it.

I don't really understand why a "machine" would need to send money to another machine. Why or when a machine would need or want money is beyond me. I thought money was an invention for people, not for machines.

How is your self-driven car going to pay for it self, when going through the car wash? Paying parking?
How are people going to pay your self driven uber car(taxi)?

The possibilities are endless!

So do the JetCars arrive at the same time as the switchover to connected cars? The graphic referenced above is way cool and really impressive. Including the item where the IoT universe is worth $7.1 Trillion, which is supposed to be larger than the 2020 Russian GDP. I wonder how the Russian people feel about that? Looks to me like we need to get on the stick and start replacing cars at a furious pace if we want 90% of the cars on the road to be "Connected" in 2020. Maybe folks will just be so dazzled by the possibilities they'll run right out and replace their car. I am sure the.

The costs are staggering and completely out of line with reality. Maybe this can become part of the 2016 Presidential election discussion, after of course we dispense with Planned Parenthood and reducing taxes on the wealthy.   Smiley
860  Bitcoin / Mining speculation / Re: with S7, bitmain vs spondoolies becomes interesting on: September 22, 2015, 08:26:31 AM
with the S7 announcement, bitmain might have nudged ahead. Now, what do u think guys, will there be a new product launch from spondoolies or an upgrade to the existing line.

They are coming out with Sponodo Gojan Heights https://bitcointalk.org/index.php?topic=1150920

Feel free to follow the link and asses it's accuracy for yourself. Just remember that this is the SPECULATION sub-forum, and claims here should be treated accordingly.

Even if it were accurate, a 7TH, 3.5KW miner isn't all that impressive now.
