if this is their legit web and not scam
koiminer.shop
seems like good and cheap product,
I wonder if anyone of the mining OGs here ever used or seen one
If that's their domain the website is pretty new 2 months old and I watched a few reviews out there it seems legit but they don't promote that domain. So I don't think that website is safe than buying from their well-known authorized reseller one of the Youtube videos that I found is pointing bt-miners.com where you can buy this unit and it is cheaper than buying on koiminer.shop and the domain age is 1 year old but the problem is only one user here on the forum mention this website. So it's risky to buy that miner on both websites unless you are willing to risk your money? And take note we know Chinese sellers always have bad support for any technical miner issues and it is always the best to buy well-known and tested miners with good tech support. |

Do you mean how long does your Miner run? I don't know about other ASIC machines but Antminer and Whatsminer units have Elapsed time under miner status or Cgminer status. Look at the image below  |

Do all 3 hash boards seem fried? Did you try to check them physically? The logs say it could be a PSU or hash board and mmboard couldn't detect it properly according to this logs below. HASHS[1 1 1] POOLS[0] SoftOFF[3] ECHU[131073 131073 131073] ECMM[5] All hashboard might be overheating that is why the system status shows 0 hashboard because this miner has temp protection and all hashboard will automatically be disconnected. If you have the extra same unit it would be easy to troubleshoot the issue. I suggest you learn how to read the logs the old description logs is removed from Canaan support so download the PDF file directly here below - Log Description.pdf |

Why not deal with someone here or do P2P if your purpose is clean Coins then buying BTC to P2P exchange or someone then uses a mixer can make your coins clean. There is someone here who accepts any payment methods except Paypal or go to P2P exchange like https://bisq.network/ it won't need any KYC or to be bank just to have a bitcoin if you want to make them clean after you buy those coins then use a mixer like Chipmixer or any other tumbler out there to have a clean Bitcoins that you can put in your ATM machines. But if your purpose is to receive new coins then the only option is to find someone or a company that mines BTC and I think only pool operators can provide such a thing. Or mine with yourself you can buy hashrate on some marketplaces to mine Bitcoin like Nicehash Marketplace or Mining Rig renatals I'm sure you can get new and clean BTC. |

Currently, only one site that I know can provide VCC without KYC and it was discussed here many times but I do not see someone here using it except for YouTuber's reviews. Anyway, here's the website https://paywithmoon.com/You can try it with a small amount but take note this paywithmoon does not work on Amazon according to them and their Twitter account seems still active. |

It seems that they do not support windows 7 as of now so you can't able to use the latest version of Electrum. And it seems there is a new pull request they are going to add the latest python version. Your only option if you stay want to use Electrum then use the older version just like what I said above or try to contact or raise your issue on the Electrum Github page. Or your last hope upgrades your OS to at least Windows 8 or 10. |

So the unknown device that accesses your account is using a Samsung device? A mobile phone? And added a Hardware authentication? What exactly do you see on U2F on the settings it should have the name of the hardware device. I never heard of any U2F fido that supports mobile except only one hardware device through NFC. The bad thing here is if you own that account why you didn't add 2FA authentication? That's the bad practice to protect your account and actually, that is the basic thing to do to protect your account. And I think you won't be able to add hardware authentication without Email access unless the hacker also has access to your Email and password? I think no one here can help you better bring your issue directly with slushpool support help@slushpool.com or contact us. |

I don't think the link on the GitHub wiki that you referring to is the right error code description. It's for Avalon 8 units so it might be different on 1166 pro. According to their troubleshooting manuals for PS or Power State, this should be the description below. The meaning of items 1-6
is as follows:
Item 1: Error code. Normal
is 0. Other values
indicate power failure or
output short circuit.
Item 2: Voltage supplied
to the control board.
Normal is 12xx.
Item 3: The voltage
supplied to the hash board
(HASH board) is normally
between 1200 and 1400
(unit 10mV).
Item 4: The current output
by the power supply to the
hash board, which is
specifically related to
the output power and
voltage.
Item 5: The output power
from the power supply to
the hash board. For 104x
models, the normal value
is between 1800-2500 (in
W).
Item 6: The expected
the output voltage from the
power supply to the hash
board. This voltage is
configured by the control
board.
If the six parameters of
the power PS field is all
0, the control board
cannot communicate with
the power . The first part of your ps show abnormal so your PSU issue might have a short circuit or your PSU is failing. What I would like you to try is to replug all PSU cables and ribbon cables then try again. Also try remove 2 hashboard and run only 1 hashboard then check the logs for changes. |

So you need to detach the lost heat sink and use super glue to fix it properly.
There is no super glue that you can use to reattached the ASIC heatsink I'm sure it will burn and lose right away after ASIC chips get hot. You need a proper glue or adhesive that can withstand high temperature like arctic silver. |

I REMEMBER THAT I DIDNT KNOW how to put a password , so no password
when i look with hex i find wallet.dat but no address and nothing looks like a wallet
Since you said above that you can see any hex code that looks like a wallet then maybe your wallet.dat is encrypted with a password. Why not try to extract the wallet.dat file from your hex tool and then try to install Bitcoin and import the wallet let it sync it for a while or use the pywallet from jackjackjj as suggested above and then use the dump command to export the private keys. Make sure you have python installed. Here's the command: python pywallet.py --dumpwallet --datadir=. > wallet.txt |

Try the suggested above by installing the latest version of python but if it still does not work I suggest you raise your problem directly on their Github page so that they can release a new version that supports Windows 7 or a patch that could fix your issue. Also, would you mind to try using the standalone or the portable Electrum? try them and maybe it will work than using the Electrum installer or you can stay using 4.1.5 Electrum and wait for another Electrum release. |

What wallet actually you are using most of the wallet apps out there have the option to put a label or description so if you can tell us the app where you sent BTC maybe we can give you some links or guides that will help you how to put a label or description with your own wallet without using 3rd party tracker.
Like sample Electrum as suggested above the Electrum wallet on PC have the option to put a description but if you are looking for a mobile app Electrum also have an app but you can't able to put a description instead you can put a label which is I think what you need you can also use it as watch-only if your wallet is not Electrum.

Where do you get or download the Electrum 4.2.0 version? Make sure it was from electrum.org
Also, try to reinstall the latest Electrum just make sure that you already have wallet file backup before you uninstall Electrum and install the latest one.
If you have any installed Anti Virus I suggest you disable it first before you install Electrum.

I think it won't be able to find the key to sign, Bitcoin core keypool size is limited to 1000 addresses by default. But you can adjust your keypool size above the 1000 limit by adding this command below on Bitcoin.conf Change the number how much addresses size your want more than 1000. Or you can use this command -keypool=<n> just replace <n> more than 1000. Do this in your offline wallet before you export parent_desc and import it to your online Bitcoin core watch-only wallet. |

Did you buy this unit as a used miner?
There might be a loose heatsink that causes overheating you will need to disassemble the unit and check physically.
Sometimes it's due to the broken or shorted capacitors that is why the temp increase so fast and automatically drops for overtemp protection.

Any miner-related website is always blocked with Kaspersky so you must disable the antivirus before you can properly access them.
Or alternatively use a mobile phone to set up your miner.

what are your rates for buying Bitcoin? Why don't you just buy BTC in exchanges? Did you try to contact pool operators? Maybe they can provide service in your Bitcoin ATM check this https://miningpoolstats.stream/bitcoin then contact them and maybe one of them can provide the exact service that you need. I don't think someone here will take this offer unless you offer higher than the current Bitcoin price. So if you want to buy BTC at the current price buying directly on exchanges is best than looking for miners here to provide BTC in your Bitcoin ATM. |

hey!
I have been about to buy the antminer s17 with this distributor (Dovina) and as I see in the comments I do not think it is a good choice to buy there.... Do you think it is advisable to buy on the official website of Bitmain? is there any seller of Alibaba that you recommend? or another website?
Yes, it's recommended to buy directly from the manufacturer or authorized distributor you will most likely scam if you deal to unknown resellers. you can also try to contact this man offordscott he is the one that I know trusted selling miner. Or try to check this website https://www.zeusbtc.com/Used-ASIC-Miner/ |

Hey
I purchased these miners used.
One of the boards is completely missing, so that would explain why Chain[0] isnt detected at all.
However 2 days ago Chain[1] was working but now its not working, from your experience, what is the most common reason for this?
I did transport the miner from one house to another, could it have broken in transport?
Did you replug the cables and the issue occur? would you mind to try running one hashboard with a known working cable so that we can check if it just a cable issue if not then try to upgrade your firmware to the latest version. Sometimes it can fix this problem by upgrading it to the latest firmware also, check the miner hashboard physically, and maybe a few of the heatsink is loose. |
