I have some bitmain coupons let me know if you want them.
Bro, what kind of coupons you have? I got them from him, it was a $41 and a $153 but they expire at end of January and will only let me apply them to spot orders which right now is limited to the S9's of which these both only will credit about $10 to the order - was hoping to use them on a T17, at least to use the 153 on a T17 and maybe the 41 on a S9 but that 10% of order thing just kills the coupons. The spot order thing is new, my 10% Jan 31 coupons allow me to allocate them to any type of order. And you can combine them. But you can't combine them with the unlimited date coupons. |

Might as well use the $41 one as you'll only end up with being able to use 10% of the value of the final price of the T17 after you take the credit off, which will be about $543 so $54.30 credit on any of the 10% vouchers. Sell the others.

mine were straight $150 coupons - only restrictions are that order had to be over $500 to use them.
The 10% coupons are for the T17 and T17E purchases that have been shipped at end December. They have face values of either $67 or $140 of the ones I have seen. And they expire 31st Jan |

Hmm, ok. Antpool fee for pplns is 0%. That is reason why i chose them. Maybe I will try slush pool to compare profit.
Antpoo PPLNS is 0% fees, but no Transaction fees are paid to miners. Transaction fees can be as small as nothing, but can be more than 1 or 2 BTC on top of the 12.5BTC reward. |

I have the following for sale.
Already located in the US (Missouri) so no hefty import duties.
All miners include PSU's
Miners that are running below spec usually are down one board.
1 x Bitmain S9 -10.5TH @ 10.5TH - $65
1 x Bitmain S9 -10.5TH @ 6.8TH - $50
1 x Bitmain S9 -11.0TH @ 7.5TH - $55
1 x Bitmain S9 -11.5TH @ 11.5TH - $75
1 x Bitmain T9 -11.5TH @ 11.5TH (Braiins OS) - $70
1 x Bitmain T9 -12.5TH @ 12.5TH (Braiins OS) - $75
1 x Bitmain T9 -11.5TH @ 11.5TH - $70
2 x Innosilicon T2Turbo @ 24.0TH - $350 each
Shipping is extra, depends on how many you want and where you are.
Offers considered, also can talk discounts on a job lot.
Escrow is fine, but its at your cost and has to be with a reputable escrow from this forum such as ognasty.
Check my trust, lots of deals done, some with escrow, some without.
Cheers
Do you still have the S9 miners? I've got an ebay buyer who has bid on them, but not paid yet. |

I know what he is talking about, we are talking about -5 and below. I'm seeing the same problems, probably at the same location. 2019-12-13 13:53:24 driver-btm-api.c:243:check_bringup_temp: Bring up temperature is -12
2019-12-13 13:53:24 driver-btm-api.c:196:set_miner_status: ERROR_TEMP_TOO_LOW

If it was me, I'd go for the S17-Pro 53TH in January and get a credit on my account, or paypal balance.

No what is true is one guy blew 2 of them up feeding 245 volts to them.
No one has had any other issues and reported them here
I've had two that have had their PSU's die, out of a batch of 10. So 20% PSU failure. Outside of warranty of course  Actually the miners were outside of warranty but the PSU's have a 1 year warranty so were still within. However after they are shipped to Bitmain US repair office, they reported back that there were faults on the hash boards as well. I suspect that when the PSU goes it takes out the hash boards as well. Anyway I had to pay for the hash board repairs and shipping but the PSU should be a free replacement. |

Thanks for the clarification.
So free to download, but not free to use. Got it.

Where did I ask you to pay?  Please keep it on topic. Don't really want the thread going off-topic on the first page. But the Second page I say we talk about mining bitcoin with extra electricity the airplanes generate. You asked me to pay in the part of your post that I quoted. Anyway, how is it off topic? Its about this firmware, I quoted what you wrote in the first post. I just want to know before I install a firmware whether it is free or if I have to pay a fee to use the firmware. That's not unreasonable is it? Is it free, or is there a 2.8% fee? And if there is a fee how is that fee collected. |

Free – Download and begin using immediately. Small 2.8% fee to keep the project going.
So... Not free then. |

It appears this model is very sensitive when it comes to temps (it must be to protect the cheaper/weaker chips used in the T model as compared to the 'better' ones used in the S models?! ).
I believe now that the power off (weird as it stopped hashing but the ventilators were going at 100% I believe) mode was due to protecting the hashing boards.
What I still hope to understand is why did it reoccur even after disabling the fan limit.
This has not happened again in the past 21 hours
When the newer bitmain miners stop mining due to heat the control board stays alive, just the hash boards are powered off. |

Its all random luck whether you hit a block or not. Probability may play a part, but really its just luck.
Just like the lottery, there is as much of a chance as someone who bought one ticket winning the lottery as someone who buys 10,000 tickets.
Even if you extrapolate it out to pools with EH worth of hash power, sometimes they have unlucky streaks where they don't get the amount of blocks they would "expect" to get in a given time frame.
If you break it down, the biggest farms only hit a block with a single miner in that farm.
At the current network difficulty, a 20TH/s miner has an approximately 1 in 32006 chance of finding a block in a day
So in answer to your question, no you don't need the same amount of hash power as the current diff, yes there is a chance you luck would be better mining an "easier" coin.
Why don't you just try for a while, you have plenty of time while you wait.
