The question is more likely decrypting the sha256 hash no one has yet been successful to decrypt it.

Or it is more likely you sent BTC and want to reverse the transaction? but you can't able to reverse the transaction however, you can replace it.

This question if you search a little bit through Google there are many explanations about this no one has yet can able to reverse it.

I'm using Kucoin but not for future trading I only trade a few coins on their spot exchange and same here I don't have KYC verified.

I already check their faqs and search about this but nothing explains about the rate the fee structure is just likely the as Binance.
So I think like others said it would be better to bring your issue to their support or you can contact them here on the forum they have an active thread here check the link below.

Sorry but it's hard to troubleshoot without the hashboard on hand.
And those signals you talking about are for ASIC chip not for sensor temp.

And also, I just want to you to try, and maybe it's only a software issue like I said above try to flash the unit with stock firmware from Bitmain and then try to flash the hashboard with a hex file that came from working hashboard.
If you don't know how to flash the hashboard check this link below.

And what I'd like you to check is the temp sensor checking them visually is not enough you need a working temp sensor if you have extra hashboard you can desolder the temp sensor to replace them. This is the way how I repair replacing the sensor with a known working one is my way to test them as according to your logs it's pointing to your temp sensor.

Please read figure 19 for the schematic and how to check them I already post the zeusbtc link above.

Don't enable SSH and close all possible open ports so that no one can able to hack your miner.

Also, protect any device connected to the same network to avoid viruses and malware, and don't use nicehash to mine and only mine in the real pool.

Bitcoin is not the same as a grin/beam coin where you can able to send offline sending Bitcoin still needs the internet to be able to broadcast the transaction to the mainnet.

You can make transactions offline but you still need an online device to create raw unsign transaction and sign it to your offline device.
So it still needs the internet to send Bitcoin.

I'm talking about the resistance of those capacitors near the temp sensor voltage output is different.


Would you mind to reflash your unit to stock firmware and letting it run for a while and copy the kernel logs and post it here?

If you don't have knowledge about repairing this I suggest try to contact zeusbtc and maybe they can help you with your issue

I just want to add this the confirmation time also depends on the network it is sometimes congested which leads to other transactions being stuck on the mempool that is why there is RBF to remake the transaction with a higher fee.
All transaction with high fees is always in high priority.

@sekssonikk actually in Bitcoin you can't cancel the transaction what you can only do is to make/replace another transaction with the same inputs and increase in fee.

Are you using different IP and device every time you log in to your Coinbase account?

It sometimes happens to me when logging in with different devices and IPs since the mobile internet keeps changes every time you turn on and off the data.

I suggest you to try logging in with their app instead and wait for 24 hours let see if it still locked.

Banks have their own purpose don't compare them with Bitcoin because Bitcoin is different you can use their wallet as your own bank but the price of Bitcoin is too volatile you can't just put 50% of your funds into Bitcoin without knowing the Bitcoin history. Bitcoin is an asset it is likely the same as gold the only difference Bitcoin is too volatile.

And take note banks have their own security to protect your funds, unlike Bitcoin which depends on you how you protect your wallet.

Electrum wallet in mobile RBF is enabled by default you don't need to change anything unless you check the final button after making a transaction.


To make this thing clear I'll add an image below to make sure you won't get lost



As you can see the final is check just uncheck it to enable RBF.

That's pretty bad she doesn't know that the website is new and it's pretty risky to deposit any amount to a website that doesn't have any reputation yet.

Why don't you just tell her frankly that the website or trading site is a scam?
And you don't have power to retrieve them since crypto is irreversible.

Actually, I also have a friend who experience the same thing just a few months ago she told me that she had a balance/funds from a broker/trading site but he can't able to withdraw I told her after checking the website and domain age the site is new and I frankly tell her that the website is a scam. However, she doesn't believe me because YouTube gives her some proof I tried to check YouTube but all of them are fake with comments turned off. She was attracted by the free reward which is why she ended up registering and using a voucher code just to earn the reward but can't able to withdraw.

So I guess it's also happened to your friend

Well, it doesn't work for me maybe because of my browser protection.
And even it doesn't have any viruses when scanning with virustotal it doesn't mean it's not malware or doesn't contain any viruses the first thing that you can notice is they do asks for a seed phrase and then the password old Multibit wallet does not generate a seed phrase instead it generates anyname.wallet file. So it's obvious the owner of the site or the hacker doesn't know anything about multibit wallet.

There are no NFT games right now that give you big rewards but if you love a card game like splinterlands you can play on their tournaments with potentially big rewards. But this is not easy you need to have a good strategy, cards, and knowledge to be able to win in the tournament there are many smart players there but if you have good skills then you can win the game.

Sometimes the game tournament rewards are around $1,000 in Dec.

Do you think your friend can remember the design of the pool website?
It's hard to guess without more details about that pool.

Anyway, Slush pool and f2pool that I know pools launched around 2010 or 2011 but if you are looking for a list then check this below

- https://en.bitcoin.it/wiki/Comparison_of_mining_pools

It includes shutdown pools and maybe one of the pools listed there is the pool that your friend talking about. If it already shut down I don't know if you or your friend can still retrieve that mined coins except on pools that still operating.

If you only have 1000kwh per month for Bitcoin mining you can only use S9 miner that consumed around 1400w per hour and around 1000kw in a month.

Or if you are looking for Bitcoin miner that doesn't consumed much power check USb miner like Compac F 48 pieces of them can hash around 14.4th/s with very low power consumption.

According to adobe yes it can contain viruses and malicious code that can potentially hack your device or PC.

Why not check Adobe they have their own explanation about this here below

To me, Binance didn't ask again for KYC documents except on facial scan due to 2FA reset but until now it didn't ask for another KYC.

I think the reason why it asks again for KYC verification he might be accessing Binance with different IP and device.

Or maybe it asks for KYC due to country regulations since they said all countries have different regulations so that's probably the cause.

If you are running Raspi I suggest install Bitcoin core with Snapd enabled to make bitcoin core work in Raspberry Pi.

There is a guide on Google if search it but you can check the guide below.

- https://snapcraft.io/install/bitcoin-core/raspbian

I tried to access the link you provided but when I tried to download it redirect me to the restoration page where you can put a 12-word seed and password.
Why would multibit ask for a seed phrase and password?
I tried to put the seed phrase and password but when trying to click download nothings happen so how did you download the malware?

And look it's obvious it's fake because it asks for a seed phrase and password in an unsecured way.

That is not the capacitors that im talking about the ceramic one brown color it looks like this below.



So the previous owner did broke the hashboard by leaving it without a fan that can cause burn parts.
