 ... and there it is: block 420000 and the reward halves to BTC12,5. It was good while it lasted. But will the halving have much effect on the bitcoin value, which is already riding quite high? The halving will almost certainly have an effect on the price, what that effect will be.... no one knows....... |

If I pay 3 BTC for the miner, the electricity cost doesn't change the original calculation. Whatever percentage of the earnings has to be sold off along the way for fiat in order to pay for electricity doesn't change the fact that I still need to earn 3 BTC from the miner to ROI in the long term. BTC to fiat exchange rates can complicate how much BTC has to be sold off along the way, but the long term amount of BTC that has to be accumulated remains the same.
Otherwise we are back to another conversation that has been rehashed in this thread repeatedly which is the "buy BTC and hold" or "buy the miner" conversation.
My point is just that when someone posts some version of "these will never mine the BTC they cost, why are people buying them?" and then someone else posts about how buying the miner is gambling on BTC going up, they are having two different conversations. Which is exactly what happened in the posts preceding this.
I've actually found myself at a different mental spot, probably delusional: So long as my miners can produce enough BTC to buy the next round of technology (based on power consumption levels), and produces enough excess that I can cover the power used to do the first part, I'm happy. If that excess allows me to buy a few things along the way with BTC, all the better. So far, that has been the case for me. Purse.io provides a convenient Amazon vector, NewEgg takes BTC directly, and so does Gary Johnson for President - good enough for me. I do that with a power budget is about 9KW/hour, enough to roughly run (6) S7s and/or S9s plus a bit of older scrypt gear. I judge my success when new technologies appear, so did so when the S7 came out, and again when the S9 came out. This is a hobby for me, and my BTC balance is influenced by other things, like surprise profits on alt coins I created 2 years ago, but that is all part of the hobby. e.g. I've "wasted" a ton of money on techs that never paid out (remember Antminer U1s and GridSeeds?), won fantastically on others, and have some that only time will tell. However, overall, both me and my spouse (who helps on the spending side) are happy. In fact, my spouse encouraged my recent S9 B5 purchase, which I suspect is reasonably rare. Rare indeed, it's taken 4 months of running these miners before the wife even started to warm to the idea. Of course it didn't help I had to tear open walls in the recently renovated basement to do so, but so far the tongue-lashing has been worth it. Edit: Adding picture of "grounds for divorce" as she put it.  |

I only got .3 at 630 or so. Oh well.
Still sounds like a snagged a good deal at face value, makes me wish I had some funds I would have been buying too. |

You may be stuck buying a 1600w PC PSU which will take 120-240v.
I can't say how well they will take constant voltage changes, but if it's within the range they will certainly work.
Look up an eVGA 1600w G2, they're around $360 USD.

I am planning for 2 x S9 purchase
just having a doubt, few are saying that mining wont be profitable after halving
Is it true?
Most profit depends on your expenses. Like your electricity cost? Are you running it in your house, if so its going to be hot and you may need more cooling, etc etc. But I still think its profitable. I just purchased my first S9 and plan to get more soon. The efficiency is there and I am in a good spot for electricity. Does AC is required for more cooling or table fan would be enough for 2 x S9? Planning to run it for 24x7 how much temp does it reach when we run it for 24x7? It will put out roughly 200cfm of 50-60 degree air, operating at room temperature, basically a 1200w fan-driven space heater that sounds like a vacuum cleaner lol. |

Planning to run it for 24x7 The S9 B3 I have seems to run a couple degrees cooler than my S7's in the same environment, keep in mind the S9's also use a 6000RPM fan on the front so they can certainly be louder. They will often grey out the button if the USD/BTC/CNY price moves too much, and will update the price multiple times daily if necessary.
You are probably right they are sold out, still took longer to sell them than I would have expected. Hopefully this means the batch 6's will have another decent drop in price.
Do you really see the price drop ? Batch 4 12.93 TH/s 3.05 BTC Batch 5 11.85 TH/s 2.77 BTC Yup, 2.77 is definitely less than 3.05. Never said it was a better value. |

I was worried about that when I heard they had made their own fork of cgminer. Maybe someone has the knowledge to get the necessary information off of an S9 but I haven't a clue how to connect into the OS of an antminer.
It's inconvenient I can't see the temps, but at least it shows up.

We don't have an s9 miner to test against.
If someone has the app open, press CTRL + D and enter your s9 IP address + port. Can you paste the results here?

SHA256 has been down for 2 hours, any word on a fix? That profitability going un-mined  |

cryptoGlance working with antminer s9 ?
It should Cryptoglance does *work* with the S9, but you won't get all of the details such as temps and fan rpm, I'm guessing due to changing from cgminer to BMminer which appears to be a proprietary fork of cgminer.  No BTM 0 page or anything, I'm sure there will be an update eventually  |

Hi Guys,
Have 2x S9's running for over a week now, but I mentioned something strange...
I spotted some screenshots of other peoples S9's and Fan1 always runs slower than Fan2.
But here it is different? My Fan1 is running -faster- than Fan2 on the back?
Fan1= 3850 rpm Fan2=3360 rpm.
What do you think? Little mistake by Bitmain or more people having noticed this with batch 2?
The S9 uses a different fan configuration than the S7. It has a 6000rpm fan on the front (also used in the S7-F1's) and the usual 4800rpm fan on the back of the unit. I can only assume this is due to more heatsinks and the longer case needing more air movement. On the plus side I find the S9's run a bit cooler than my S7's in the same environment. Albeit a touch more loudly. |

Finally after a couple full reboots, and the new 06/24 firmware my Batch 3 is now up to spec , out of the box board 2 was underhashing, though the HW errors were never that bad. Now she's hashing at 12.93 on Slush or Nicehash, and working through my stratehm proxy without a problem. Not too bad for early batches, gotta figure this means these units were barely run if at all on their way out the door. |

Hi guys, my name is Martin and I am a support guy from Slush Pool who is going to post here from time to time. In order to prove I am from Slush Pool, please verify the message I just signed for you with our mining wallet below. Unfortunately I am not able to put this signature into my profile because I am new here.

Reasonable doubt met with reasonable evidence! Don't see that often enough. Double verified as a valid sig on a Slush wallet with Electrum 2.5.4, welcome Martin! |

Why do the 250v cords look like this?  This is a 6-15 plug intended for use with 15A+ @ 120V/240V, the 5-15 socket you are looking for should not be wired up with over 120v. 6-15 for 120v/240v  5-15 for 120v ONLY This is merely advice, the image of the 5-15 comes from http://www.digital-loggers.com/cords.html, I did see specs for a 6-15 to C15 C19 cable on there, no pictures though. Hope this helps. |

Finally got my Batch 3 today, almost lost it on UPS when it still hadn't shown up this afternoon, at last it arrived just as I'm sitting down to dinner  Runs beautifully, great numbers, got a massively irritating whining fan on it tho, fixed with a touch of duct tape and some furnace filter material . All things told it's really disheartening to see the price plummeting, I'm just ecstatic I bought this S9 with BTC when I did, if we have some low/negative difficulty numbers as a result of the price drop I'll just take the bad with the good. Here's hoping it's an inverse head and shoulders scenario as some people have postulated. |

I finally found the video! https://youtu.be/nbQr9NDtIiAThe eVGA units are certainly more expensive, but well worth the 10yr warranty. I had one crap out after two months and they shipped me out a brand new unit, in box with full warranty, in 48hrs. As the video shows, they are demonstrably more efficient than the Bitmain units, and if someone is claiming they are more stable I would not hesitate to make the switch. |
