No, it's not normal for Bitmains PSU since you are using a Chinese PSU I don't know how this PSU works. Usually that kind of issue it's due to leak or maybe have broken capacitor if you have a multitester that could read capacitor from your PSU you can check those broken capacitors. The multimeter that I use looks like this  You can replace that broken capacitor with the same value. |

Sometimes the wallet.dat is corrupted if you copy the wallet.dat while the Bitcoin core is running on the background and maybe you made a backup copy while the Bitcoin core is open. I have experienced having a corrupted wallet.dat the size of the file that I copy is different from the original. I'm lucky that I didn't remove or delete the wallet file under bitcoin core data folder. So your problem is you have a corrupted wallet.dat file I'd like to suggest you to try dumping the private key from your backup through pywallet.py check this guide below If that doesn't work, you'll be down to the very last resort... which is the process that this guy used: https://bitcointalk.org/index.php?topic=1404609.msg14257235#msg14257235It involves getting a small USB stick (preferably 1GB)... wipe it clean (delete everything off it, format it etc) and putting just your "corrupted" wallet.dat on it. Then you have to manually run the pywallet command from the commandline to get it to scan your corrupted wallet.dat and try and recover private keys. Assuming you had a 1GB USB stick and it was showing on windows as D: and you "extracted" PyWallet to "C:\PyWallet" (when running the PWI_0.0.3.exe): Step 1. you would put (a copy) of your corrupted wallet.dat on the USB stick Step 2. Start -> Run, Type cmd and press enter Step 3. cd \PyWalletStep 4. pywallet.py --recover --recov_device=D: --recov_size=1Gio --recov_outputdir=C:\PyWalletIf your USB stick is larger, change 1Gio to what Gigabytes it is... 8GB = 8Gio, 16GB = 16Gio... if you use a stick larger than 1GB, be prepared to wait a LONG time while pywallet scans it. After that finishes, it should have created a "recovered_wallet_DATESTAMP.dat" that you can attempt to load in Bitcoin Core... or use PyWallet to dump the keys  |

I don't understand what actually you want to explain but it seems that you want to pay BTC directly to a payment address? If the payment address you talking about is the address of BTC he will receive also BTC there are wallets that automatically calculate it in USD. But if you talking about BTC then you are going to buy something online with your BTC through a debit card with a BTC balance then there are still available online like Coinbase card you can find it here https://www.coinbase.com/card you can spend your crypto with this card and sellers who paid with Coinbase card will receive USD. Another option that I know of is https://paywithmoon.com/ where you can able to deposit supported crypto and generate a VCC that you can use to buy anything online or to pay someone that accepts VCC. However, I don't know if this is still operating but their website and Twitter are still active. |

Take note if you talking about a computer then it's no longer able to mine Bitcoin blocks.
There are different types of mining to the pool you can mine solo or join other miners/pools if you found some miners with low hashrate(computation) who are trying their luck those are solo mining they mostly called it a lottery.
There are still mining with GekkoScience NewPac or any USB stick built with ASIC any computer without ASIC chips is no longer able to mine BTC.
Since the ASIC is developing the higher the hashrate the higher power consumed by each miner. The manufacturer keeps developing a miner with low power with high hashrate.
About the fees, if you are mining on the pool it depends on the pool which fees they will include on the block so the reward will still depend on which mining fees they would choose.

So the error only occurs when you exit the Bitcoin core? If you want to use the BTC right away exporting it from Bitcoin core and import it to Electrum would be the best option. Can you try to dump the private key through the console? You can find it under window>console I don't know what UI looks like on Mac but you can use the image below as a reference  Then use this command walletpassphrase yourwalletpassword 600 And then after that use this command below to dump the private key dumpprivkey yourBTCaddress Copy the private key and now download Electrum from https://electrum.org/#downloadand import the private key there you can follow the guide from this link below - https://bitcoinelectrum.com/importing-your-private-keys-into-electrum/ |

Be careful on buying a miner on unauthorized reseller or non-verified distributor you will end up receiving problematic units with no warranty support. Just like what Bitmain said they don't support if you buy miners from non-authorized/distributors. You can buy a used miner but always find the trusted one that can help you troubleshoot in case of any issue related to the miner you buy. If you are looking for cheap units I suggest you contact offordscott or check one of his post from this link below - https://bitcointalk.org/index.php?topic=5187550.msg58896176#msg58896176 |

If you are going to use a used miner we can't say if it can mine stable or if it has some defects unless if you buy them directly from the manufacturer. Also, Innosilicon has some bad support so I don't think it's a wise decision to buy that miner. About the profitability of 15% per month since we are in a bear market I don't know if you can still get that 15% every month. Try to contact offordscott he might be able to help you what is best option to buy. |

can you send the command for autotuning of chips, my one chip is exceeding 120c mark and voltage is around 338, although miner is working good at 82th stable.
can you share the command line please,
thanks , looking forward for your reply
Try to refresh the miner's ASIC chips through the FMS tool you can download it from this link below - https://canaan.io/wp-content/uploads/2020/03/FMS_V2.3.3_Windows.zipAnd then look for the aging tab and select any hashboard with high ASIC chip temp. If it still overheating manually set the fan speed to 100% to test if it can help to cool down those chips To set the fan speed you must have the FMS tool and then go to diagnostic and put this command below [b][{"command":"ascset","parameter":"0,fan-spd,90"}] [/b]Fan-spd,90 it's a fan speed with 90% you can replace it with 80% or 100% to try if it fixes the issue. |

This is why I always tell newbies to buy directly only in manufacturers or authorized/verified distributors dealing with unknown sellers like AKMiner will lead to some problem or being scammed. Do they tell you that those miners that you buy are brand-new? Actually, it's your fault why did you buy miners on non-authorized or verified sellers? Next time if you are going to buy a miner please use this list here https://bitcointalk.org/index.php?topic=5045732.0Or try to contact offordscott to help you buy legit units. |

Check Coinex.com you can trade there without KYC just don't forget your password because if you forgot they will force you to verify the KYC just like what happened to me last year.
Take note to those who don't know Coinex exchange is owned by ViaBTC which is a well-known pool operator. And their withdrawal limit is around 10,000 USD in any crypto or Bitcoin.

The image is still fake he only mined 3 blocks with a 50BTC reward each but the total amount balance is 312550?
If you can share your client's BTC address here we can analyze or check the address if it has a balance or do what the above suggestion you can check it by yourself.
Another thing that I notice is the color of the Bitcoin core wallet. It seems the wallet from the screenshot is edited or a modified version of Bitcoin core.

Can you try to check the Bitcoin data folder and maybe you created two wallet.dat with different names.
The default can be found here C:\Users\YourUserName\Appdata\Roaming\Bitcoin or open run and type this %APPDATA%\Bitcoin
Then look for the wallet folder to check if there are other files or make a screenshot of that folder. Let see if you created other wallets with another name.
If I'm right you can open it again with Bitcoin core to find the exact wallet.
This error "Invalid private key encoding (code -5)" usually popups if the private key has a missing character or has a compatibility issue but since you dump the private key on the same version maybe you copied the private key with a missing character. It's just my guess.

Where did you find these commands? How would I test putting the fans back to auto? Change to "1,fan-spd,100" ?
THANKS!!!
OC
Someone share it here so credit to him and this command is not permanent you can just shut down the miner and run it again or replug the miner from the outlet the settings will revert back to the original settings. Or if you don't want to shut down the miner you can change the fan-spd to 0 and I think it will switch back to auto. |

Thank you very much for your reply. I have checked the PSU today, the output it gives is 8.8 V; is this enough or may this be a problem ?
Thanks again !
Well if the multimeter shows 8.8 volts it's not enough to run the miner check the input may be the stabilizer you talking about is not giving enough power. This miner must be run at 220v lower than that it won't mine properly. What is your wall voltage? Why don't you just directly plug it on the wall outlet? |

Do you have any installed VPNs and running in the background?
If the captcha is Google it will challenge you to solve the captcha but sometimes it won't work due to VPN so if you have running VPN try to disable it and login again on Nicehash.
Another solution is to clear your browser cache and history or just cache only then try again.
And the last thing is go to internet option and the advanced tab and then restore advanced settings. After that click the reset button and check the personal settings and press the reset button again.
Then try to login again on nicehash let see if it fixes your issue.

Yes, this is fake and maybe it is a modified bitcoin core anyone can make a coin because Bitcoin is open source.
Another thing it might be a self-hosted node install on localhost where you can mine 50 rewards for every block you mine or maybe the image above is edited.
Why not ask the client and post the BTC address here and let us check if it's true or not. If it's true then we can provide a few suggestions to recover those BTC.
