Sorry for posting here, can you be our escrow for trading bitmain coupons? Im the seller and chiragar14 is the seller he also going to pay for the services(if theres any) the amount is 2x $350 coupons for $200. And if its fine can we do it on telegram? Because we are both newbies and have pm limits or you can just hold the money and im giving you an access to my bitmain and you can transfer it to him and release the money to me. Thank you and sorry for posting this here
I have stopped escrow services so do not ask me to do them. To all I still have $100 coupons for sale some expire June 11th 37 x $100 left Others expire June 30th 6 x $100 left July 1st 2 x $100 left July 31st 6 x $100 left I will take various coins for payment. so 51 coupons each for $100 will take reasonable offers under $8 for each coupon bump |

Problems abound due to the huge fall runup.
Bitmain saw really big profits last year.
So much so they got ideas on what to do with excess profits.
I find it very interesting that innosilicon now has
A better zec miner more hash less power.
A better decred miner more hash less power.
A better sia miner more hash less power.
A better sha miner more hash less power.
As compared to bitmain.
Yeah bitmain is cheaper but the specs are better for innosilicon.

And if you're on 208V and derate to 80%, a 20A circuit gets you 1 machine (and 48% utilization); 30A circuit gets you 2 (and 64% utilization).
Though a 60A PDU and 80% derate would run exactly 5 without a lot of overhead.
208's pretty common for industrial-scale electric, even in datacenters.
And the point still stands that the power density and cooling requirements mean these'll only run where your intake temperatures are regulated to probably 60F and lower. In my farm, that means I could run one for at most five months out of the year. If someone bought one and sent it here for hosting I'd have to turn it down. Got enough trouble keeping S9s cool May through August.
The biggest reason I kept the t1s was -ck s speed control. Low 14.4 th Medium 15.5 th Fast 16.5 Th. That low setting solves my cooling issues in the summer . The company GMO now has a hotbox doing 1950-1990 watts taking money for preorders . First will it do all pools I don’t know Second can I run it at 80% to avoid overheating I don’t know. Yeah I get it that industrial spots may have really good cooling. But a lot of farms do not cool that way. |

Now I looked at it. It is paying about 2% interest a month. I simply fail to see how they can pay 2% a month. 18 million of 21 million coins have been mined. This coin reminds me of ppc I won’t get involved in pos/pow coins that pay interest. I won’t get involved in pos coin that pay interest. I fail to see how these coins can generate 2% a month. |

But many mid-size farm, like mine, have pre-wired expecting 20 amp 220V to be split between 2 devices, not one.
Never wrote that taserz wrote it. and a hard wire 2 outlet circuit at 20 amps would be asked to do 20x 240 = 4800 x 80 percent that is 3840 watts or worse 20 x 220 = 4400 x 80 percent that is 3520 watts since this says it is 1950 or 1990 you are doing 3900 watts to 3980 watts I have gone past 80 percent derate and in a hotter setup it has issues. I would not want 100 of these doing 398,000 watts which could be 3980/4400 = as high as 90.45 % vs 80% Yeah in canada or iceland not that hot but plenty of hot mining spots are around if you have robust volts (240) you are at 3980/4800 = 82.92% which may be okay My area is 239 to 243 volts which is helpful. |

Diffs sum to 1312.1 / 11 blocks = Avg. of 119.28/block (ignoring network diff increases) OUCH!!!
So basically the last 3 blocks add to 548.5 first 8 we were 765.1/8 = 95.637 these last 3 are 182.83 brings us up to 119.28 but these are very small samples of blocks. no cause for worry. pop a few 25 blocks and back on track |

So what, they're using air with a higher specific heat? Epoxy with zero thermal resistance? 300CFM fans that don't spin at 10KRPM and draw 100W to do it? Have they discovered a heatsink profile with no solidity and perfect heat transfer, and made sure to place every single one to avoid vortices?
Quality or not, the physics of air cooling is a big limitation. Look at all the issues we already have with heat unreliability on 16nm and 10nm and think how much worse it's going to be on 7nm, which has basically never been tested before this point.
Well 1950 watts or 1990 watts either way it will be roasting hot. Even if they offer a semi speed control like -ck did with the T1 (nice work on his part) Or voltage offset like the Avalon 841 I can state it is a moron move to run 1950-1990 watts on that size and shape. The density is not that important. Cooling and efficiency are important. They have began with a good chip (maybe) and put it in a moron shape. How about same size box doing 12th at 972 watts? with low medium fast speed settings. The gear they built with not like air cooling it will want ac and a colder room which makes the power savings lost. All these smart guys and they sell this in a stupid box. I tell you what does this gear come on Nov 3 since it shipped on Oct 31? And if it does come on Nov 3 How much do you want to bet that bitmain beats them to market with the s-11 with 17 th doing 1377 watts. same efficiency and cost of 1400? How will GMO look then. They really fucked up doing a pre order with Oct delivery. |

Hi,
I want to sell 3000 coupon bitmain 100$
Expiry 1st June
I want buy 1 USD/1 coupon, Negotiable, especially if u order more.
why would anyone want your coupons they expired on June 1st and are no longer any good. |

Dont know if you guys saw this,also 50k sols/1150w equihash miner but from asicminer-anyone knows if that company is legit or no?So far there isnt a lot of info about them that i could find  https://asicminer.co/shop/asicminer-equihashwho cares at this point? only the mentally ill would buy it. my reasoning is this A I have been mentally at occasional times in my life so I can say it. B if zcash ends up as an asic coin innosilcion has 50,000 sols for 10k vs 40,000 sols for 15k C if zcash ends up as a money maker innosilicon uses 620 watts 50k sols and asic miner uses 1150 watts 40k sols D if the coin burns out someone will dump one of these for 2k in under 3 months. E forks are another threat. With all these ASICs targeting POW coins, too much crazy money is spent chasing that "perfect ASIC miner". In the last 3 years, in this chasing game, I was lucky only once, getting a good chunk of early X11 ASICs circa 2016 with Baikals (pre-Giants), and it was purely by chance when nobody was paying attention to newer X11 ASICs and the sudden rise of DASH. Even Baikal probably thought they sold the gear too cheap to my group. Those were the days. Today, the game is well beyond our control, we get scraps and the "membership fee" to the mining club will soon start 10k and above. Currently, my group's crypto earnings shows, more than 50% now comes from crypto-currency trading, 30% SHA256 and only 20% from GPU and other POW ASICs. I think its time for us to re-think our mining strategies, otherwise we just wasting money supporting Bitmain's evil gameplans and experiments. Experienced miners doing trading gets better results due to our knowledge in crypto mining and how that coin is mined and supported in the crypto ecosystem. Therefore, why not invest directly into that promising new coin instead? For me trading is a no go,but I want to develop solar. I have a pop concept . The thread is in spec sha Mining. The game at this moment is cheap power. So if you can get a solar setup for the correct price any gear makes money. If you install a 1500 watt setup that mines off grid without a battery you have full power for an average of five hours a day. More north maybe four hours a day more south maybe six hours a day. So a 1500 watt setup doing five hours is 7.5 kwatts a day . If you figure a year it is about 2700kwatts. At ten cents that is 270usd in a year 1080usd in four years. The key is that a proper solar setup is good for ten plus year. So you are getting 2700 usd worth of power. If I can make this setup for 1000 It is a good deal If I can do 1350 it is meh. It allows older asic to remain viable for a long time, |

I'm a little confused by the blocks vs. shifts status right now.
The last BTC block found was at height 523142 on 2018-05-17. But there are many shifts before that (2018-05-08 19:22, 2018-05-10 15:27, 2018-05-13 06:47, 2018-05-15 17:37) that are still showing in the list as "still eligible for pay".
Is this a side-effect of the PPLNS algorithm in the lucky case? Unfortunately most of my experience so far on this pool has been with high-CDF blocks where it takes say 18 shifts to snag a block, and so 8 of them get no pay. That makes sense (LOTS OF cents…less than I'd hoped to get out of my S9 in 2018 ;-)
But what happens if a block only takes say 4 shifts after the previous block and its payout? Is the reward divided between those 4 shifts, or do 6 shifts before that get rewarded a second time, or what?
Nothing I can think of quite explains why the shifts between May 8 and May 18 are still "eligible" rather than having been rewarded by the May 17 block.
All ten shifts get paid. So if you hit blocks quickly you can collect multiple times on the current ten shifts. As time passes the oldest shift drops getting replaced by a new shift. So say shifts are A B C D E F G H I J. Are live and a block comes in. All of them get paid. First block hit In a day. A drops off and K comes in B C D E F G H I J K Say a block hits then. Second block hit pretty quick shifts B to K all get paid. Say one minute later while still on shifts B to K another block hits. Third block hit Same shifts B to K get paid again. Then a long dry spell comes and B to I drop. And we are at J K L M N O P Q R S We hit a block all of the above are paid Fourth block hit And my example above shows shift J being paid for four blocks |

@ yankees I dont recall if the power supply is 5 or 7 year warranty.
And your numbers have some accuracy.
We may have to target a 20 cent or higher power area to be selling a viable product.
At the moment I have a wedding to attend and we wont be doing any real testing until next week.
The enclose I designed will work for 1400 watts or less with no overheating It can be secured or moved.
It lowers sound of the 2 L3+'s
I get the s9i's next week.
I like the idea of letting a higher power cost guy get in the game.

Please at least make it work with an S9. Also, it should be like a whole package including battery. Just a self-sufficient little mining-at-home kit. There is definitely a market for that!
Batteries are worthless. Not really but they make install harder. The key is to keep it simple. We can get new old stock panels at a good cost. The highest end panels cost far too much. But 210-240 watts panels come up for auction at decent prices. I have a prototype outside box that should work.. box\ right about where those ladders are. we found a decent dog house the fits 2 L3+ or 1 S9i the box size is fine since panels are pretty big. The test box is in my basement pulling 1350 watts running 2 L3+ |

I've also been saying that full control of core clock and voltage are necessary features but nobody does that anymore. Probably for idiot-proofing. It is handy some have at least partial options.
yeah over clocking morons caused lots of returns. Sooo no more voltage controls. To me I rather run all gear at 60 to 80 percent of tops speeds and volts. But no can do. |

I apologize if this feels silly question but I was thinking isn't Hard Disk mining like storj or burst safe from ASICs ?
good question I do not know the answer but my guess would yes. Since you need to proof size of storage to earn coin. you could try them |

I've been saying exactly that for three years, since S7 rolled out, but it looks like that kind of high-dense chipsinked package is becoming everyone's de-facto standard (except Avalon, thankfully).
There's no good reason not to build KW/sub-KW miners. Site density stopped being an issue back when people started using shelves instead of racks.
1.4KW is already difficult in that case size, without adding half again to it. Especially since all evidence points to smaller nodes having more issues with heat density in the dies, so the chips probably can't be allowed to run continuously at 120C die temperatures without a high risk of roasting before the machine's expected end of viability.
add on the lack of speed control. they will run balls to the wall. Avalon has various settings one is about 990 watts Halong t1 with -ck firmware low setting is about 1300 watts |

GMO is using TSMC as well also don't forget GMO coming in has a lot more money than all these other players. Even bitmain so it's not like they are coming to the game short handed.
Okay so let us say that GMO is bigger $$$ they still went in the wrong direction here. Most miners even 1000 unit miners have space to spare They are short with cheap power They are short with cooling issues. I can run 3x my current amount of miners and still have space left over I have lots of space. Packing all the power into a small box is dumb and asks for trouble. Forcing a use of a 2200 watt psu and pulling 1990 watts against it is meh. Running a 12th doing 995 watts is so easy to manage. Well Since I can't get these until October it is not a worry for me. |
