Did you know how to search here on the forum? That's the basic thing you need to learn first because there are lots of similar threads you can find here in this section.
Sample this one "How do I start trading? and Where can I learn trading? if you don't know how to research you will never learn how to trade.


And here one my post on similar thread that I think is what you looking for

Be careful don't do this first


I heard that someone before that his old wallet file or wallet.dat become corrupted after upgraded it from oldest Bitcoin-qt to newest bitcoin core.
If you don't want it to happen to you then make sure to make a backup of your wallet file first or much better dump them all into private keys while waiting in your hardware wallet. You can just sweep them once you set up your hardware wallet.


If you see the received address then you can check it if it still has a BTC balance you can use some explorer like https://blockchair.com and paste the address that starts with 1QC then submit it should show the transaction history and the current balance.

That's not possible there is no button on your profile that could delete your own account.

What you can only do is to delete your old posts.
Why don't you just leave it and don't use it anymore? Unless if you have another reason why you want to delete it?

My guess is you want to use the username again and you want to clean up all of your negative trust? Well, it's just my guess.

And take note it seems it was discussed here many times "how to delete my account here?" and "Delete bitcointalk account"

It depends on your Electricity rate if you have a free power source or near 0.02 cents you can start to buy 2nd hand miners.
Start from buying used Antminer s9 and I'm sure there is someone selling it for a cheap price maybe around $200 each.

I dig up here on the forum and search on Google and I couldn't find any overclocked firmware.

There is a custom firmware that I found but it's not overclocked but it can unlock some features like SSH and fan control.
You can find it from here https://bitcointalk.org/index.php?topic=5253966.0

I found an old thread and it seems that there is overclocked firmware for this unit but you can only have them if you paid the license.
Look at here https://bitcointalk.org/index.php?topic=5132758.0

It seems that this miner doesn't support ASICboost try to use a normal pool or change or pool to ViaBTC.

The list of the normal pool is listed at this link below.

- https://www.nicehash.com/support/mining-help/mining-advanced-topics/which-stratum-servers-are-available

more pool can be found here https://miningpoolstats.stream/

The error should be what you focus on, according to the image at the end of the error says "Remove the existing wallet first!"

That is why you get that error it's because Electrum couldn't generate a new wallet with the same wallet name if you use that command it will use the "default_wallet" so if you can rename your wallet default_wallet to default_wallet1 or any other name the command you use will work.

Look at mine

It seems the current latest version of the armory doesn't support it yet but it might support on their armory 0.97 they don't release it yet.

Read this part

Look at their release note here https://btcarmory.com/0.96.5-release/

Armory does not fully support bech32 but they support segwit address that starts with 3 or with script type: p2sh-p2wpkh

If you want a wallet that fully supports segwit I would suggest you check Electrum wallet or wait for a new armory release.

What crypto tax app do you talking about?

For a reward, it depends on what app you talking about there are apps out there that devs don't care about the error.

Try to check their official website or app itself if there is a help button or use Google to search this app including bug reports if you can find that they will reward people who found errors and bugs that could affect their business then report it right away and provide your evidence.

No, it's not the same as coinmarketcap what you can see on the news aggregator is the latest news about bitcoin or crypto.

Sample this website https://cryptopanic.com/
We use it to see all news related to crypto and you can also use it as a signal for upcoming trends good or bad news still has an impact on the market price.

What do you mean to stay away from electrum for privacy?

Does it seem that you didn't understand what they mean from your old thread?

If you use multiple addresses with balances on Electrum and make a transaction to transfer all of them on a single transaction all of your addresses will show up to any blockchain explorer.
So your privacy will be compromised if you do that.

If you want privacy use only a single address to any transaction or use coin control that is why they recommended coin control if you already receive multiple transactions to a few of your addresses you can choose one address to make a transaction and don't include other balance from other addresses that you own from Electrum which increase your privacy.

It's not like you are submitting any documents it's just for the address and transaction that will be recorded on the block explorer.

---

Sample these transactions:

- https://blockchair.com/bitcoin/transaction/9dacd14278d01d1ad8001b9bc0524f24405f84022ad161ff77f8a35f272393f5

and this

As you can see on the first one the sender has many addresses and sent all of the BTC to the recipient.
And the 2nd one only has one address and is sent to the recipient

So if you don't want to show all addresses that you use from Electrum you need to control which coin or UTXO that you want to send just like what I said above. Because they can monitor those funds until it sent to another address.

PVT_T0 and PVT_T1 it's related to chip temps and according to your logs, it shows negative it means it's abnormal status running with 2 hashboard according to SYSTEMSTATU.


And another thing is both PVT_V0 and PVT_V1 it shows abnormal it's related to the power supply.

Do you have an extra miner with the same unit model? If you have then try to use it to test if it's a PSU issue.

Such an awesome live tool what is the advantage if you log in or created an account on this site?

I think inflow and outflow and a little news aggregator would make this site a better tool for analyzing the market.
I hope that you can add that.

The only thing that I don't like is why did you list the Poloniex there? Which is one of the scam exchange.

Be careful on using them with VPN it's prohibited according to their terms.

You can read this local restriction against US users and other countries.

Does it seem more countries are not allowed to use their service?

It's an instant buy fee even you are a Kraken Pro you will still pay a 1.5% fee if you want to take the lowest fee then trade on their pro version, not in instant buy on their first page.

You can use their Kraken pro app to trade and get the 0.16%/0.26% fees. Use the link below where you can download it

- https://support.kraken.com/hc/en-us/articles/360049788312-Kraken-Pro-mobile-app-FAQ

Well yes, you can still access the dashboard even there are two devices that use the same IP but not everything will work correctly based on my experienced.

Static IP from the router is not a problem it's only pointing to your ISP modem. From your miner try to change the DHCP mode to static and change the IP.
Sample the DHCP mode choose 192.168.1.10 then replace it with 192.168.1.99 on static mode.

Then test it again.

If you don't believe that it's not a network problem then try to flash it first with the latest firmware from Bitmain here and then test it if it is just a software issue but if it doesn't work well it's related to the network issue.

Even on other exchanges actually, it happens when the new ICO coin or token is listed on exchanges like Shiba Inu after being listed on Binance for a few hours it increases and massively drops after a few hours.

Anyway, yobit is doing some shady things from their exchange for many years and until now all of their charts and price movements are fake they can manipulate the price on their own exchange to get profit.

All of the active pairs that you can see there are those shitcoins and tokens which are not listed on big exchanges.
If you trade on their exchange then you just wasted your own money for nothing.

Does it seem he has a legacy wallet and is now converted to an HD wallet? And can't able to do anything from his old balance?

Can you try to ask your friend if he has some backup like 12 recovery mnemonic or the file with aes.json?

If he still has the 12 words mnemonic let him know to try to recover it through this link https://login.blockchain.com/wallet/forgot-password
Or use this link https://login.blockchain.com/wallet/import-wallet to upload the aes.json file to recover his old wallet.

Have you noticed the error from your kernel logs?

I suggest you edit your post it looks messy you can use a code tag you can find it when you edit the post with the # icon.

Look at this log


And how did you get the error "Socket connect failed: Connection refused"?
Is this the whole kernel logs?

According to your above logs, it seems you have a defective fan.

If you already upgraded it to the latest version try to flash it with an SD card flashing you can follow the guide this link below

- SD card control board program recovery

And you can download the SD card firmware from here "Bitmain SD card firmware"

Take note there are 3 different SD card firmware make sure to download the right firmware to your miner check carefully the unit model of your miner before you flash it with SD card.

Can you post the whole kernel logs let me analyze them for you?

If you have a limit then you can try to paste it here https://pastebin.com/ and then paste the URL here.

What is your room temperature?

If the error on this "stop_mining: over max temp" try to manually set the fan speed to 100 you can find it under miner's settings and set it to normal mode.

If it doesn't solve your issue try to upgrade it first with the latest version available on Bitmain and test it again.
