I never had experience using the Paid service of ViaBTC accelerator but since they own a pool they can be able to speed up the transaction.
By default, a pool like Viabtc prioritizes transactions that pay higher fees automatically. However, The pool owner or the pool operator can manually choose what transaction they want to add to the block.

Viabtc's paid service should work in this case the only problem is the paid service is a bit expensive and not good for small transactions.

The centralized Coinbase wallet(Coinbase exchange ) does not have a feature to do CPFP unless you use their self-custody wallet with seeds backup that you can import to Electrum and do CPFP transactions.

Coinbase support can't able to help you if you use the centralized wallet so the only thing that you can do right now is to wait for the mempool to become less congested.

Did you boot the Umbrel OS on the external drive? Just asking this because you said you don't want to format the hard drive.

Why not buy an SD card instead to install OS 64 GB SD card would be enough and use the hard drive as your external drive and set up Bitcoin core then point it to the external drive where your Bitcoin folder is located.
I think you can find the Bitcoin data from the hard drive in the directory below.


Or check this link below you might get some ideas and suggestions on how to backup/copy the blockchain data.

10yrs is just the expected lifespan but in my experience, it doesn't most of my USB Drives no longer work after a year or two some of them work but files become corrupted even though I take care of them very well.
Only 2 of my 8 USB drives with two different brands still survive after 4 years(transcends 16GB and Sandisk 32 GB).

Having multiple backups is also fine but for long-term DVDs is way better to handle files for more than 10 years because I have a DVD that still survives after 10 years it still works.

Meaning this is self-promotion trying to make a new account to promote his own phishing/scam site. His alt account is btcpepa04 with some negative feedback that this user keeps asking for a non-collateral loan and promoting a Ponzi scheme.
So the website above is also owned by btcpepa04 which is a scammer.

Be careful don't try to access the website he might be able to collect your IP and perform a brute-force attack on your device or PC. Please avoid.

The Cambridge book and Thomas BJ are not free you can find them on Amazon.

I know Quilbot and tried that thing but it edited my posts and it's flagged as AI-generated text when checked it to CopyLeaks AI checker.
I'm fine using Grammarly I just only use it for auto capital, auto-correct wrong spelling, punctuation, and synonyms.

How did you broadcast the transaction since you said you created the transaction or redeemed BTC from a cold wallet?

You didn't mention if you have Bitcoin core installed on your PC or if your Bitcoin core is fully synced or pruned.

The Armory wallet does not work without a fully synced Bitcoin core(i.e.: nearly full hard disk) or if it's pruned it won't also work. You need to provide more details about your issue like adding armory logs here to analyze the issue and why it's stuck.

This Armory wallet is not newbie-friendly if you want ease of use I suggest switch to Electrum it doesn't need to be fully synced and you can also make an offline or cold wallet.

Just to be clear the added passphrase/password on Electrum is passphrase protection you have a choice on the first wallet creation if you want the wallet file to be encrypted you need to enable it or disable it while using a password. Encryption is another layer of protection so that the wallet file itself is not readable(seed and keys are encrypted) when you try to open it with Notepad.



@OP Since the USB Drive has a short lifespan I suggest burn them into CD/DVD because they have a long lifespan according to Google 10-15 years but if you want a disc with a longer lifespan check the M-disc it has a 1000yrs lifespan. And don't forget while creating a wallet to make sure it's safe you should create a wallet in an offline environment to avoid someone monitoring and recording your keystroke/clipboard.

It seems you are looking for an advanced tool Coinmarketcap also does that but it is not free you will need to buy API subscriptions. Check the API guide here Historical data documentation.


Or learn how to use sheets to pull historical data to any crypto check this guide below.
- Pull historical Crypto Data into Google sheets.

Delisting trading pairs doesn't mean it would affect the price of these coins I believe it won't affect the market or these coins/tokens. Unless these coins/token is totally delisted from Binance.

There are many reasons why they remove and delist these coins/token pairs there might be fraud happening on these assets like market manipulation or other illicit practices. They delisted them to protect users from losing on trading.

Before the historical tab on Coinmarketcap was available right now it changed but it's still available to use you just don't know where to find it.

To use the historical data you can find it on the menu historical snapshot and then choose a year under that tab you can see all listed coins but it is not yet the historical data you looking for you need to click the 3 dots on the right side of the coin and then click historical data.

Or go directly to this link below if you only looking for Bitcoin historical data.

- https://coinmarketcap.com/currencies/bitcoin/historical-data/

You can edit that URL and replace bitcoin to any coins you want.

For now, we don't know when 1 sat will be equal to 1 cent because we are currently under a bull market and near blockhalving. Maybe you can buy 1 sat again for 1 cent when the bear market starts. But for now, it's impossible to buy 1 sat/1 cents.

If you can still able to access the unit I suggest take a screenshot of the unit's dashboard and post it here. We can maybe able to get some hints under the dashboard and also, copy logs and paste them here so that we can analyze the logs.

Or you can follow the repair guide from Zeusbtc here

There is no difference if you use the same device and connect it later online to broadcast the transaction.

If you are going to do that on Ledger Live this won't work unless you use a wallet that supports offline transactions like Electrum. You would need 2 PCs to completely make an offline transaction, one PC should be connected online while another PC is offline where you can sign a transaction.

There's no problem developing a wallet for gamers as long as the wallet is open-source and proven safe by other trusted developers.

There are many developers that I think already did this idea but if you can make it unique like a wallet that can be used offline/airgap and connect games through a QR code then I'm sure many users or gamers will be attracted to use this.

Based on the logs during flashing it said burn success.
Have you used any commands during flashing through the TTL method?

There is another method to flash the unit through TTL but I do not know if the commands will work on the s19j pro.

Can you try this method Recovery Method of Serial Port Bitmain also have the same guide but the problem is they didn't include the command lines? That is I think the last step you haven't tried yet(sending command during flashing).

You might have upgraded it to the wrong firmware?

How did you know it was bricked? Have you tried to access through the browser?
Have you also tried to factory reset the unit by holding the IP report button for 5 seconds?

If you already did that but can't still able to access the miner then you can try SD card flashing You can follow the steps below it requires a Card reader with an OTG plug( if you do not have an OTG card reader you can use the "Micro USB port to USB female connector") and then SD card and PC.

- First, download the s19j-Pro-a113d-amlctrl-flashCard-20211119.zip
- Extract the file to the desktop
- Copy all extracted files and paste them into an SD card(Make sure to format it to FAT32)
- Now plug the OTG Card reader with SD card into the unit then power on
- Leave it for 30 seconds to flash.

Once it's done test the unit again and update here.

If the backup private key was generated from the year 2009 to 2010 I'm sure it was not created from Armory or multibit wallet because these two wallets was announced between year 2011 and 2012.


If it starts with 001 then it's a binary format you might need to covert it to the WIF key format to be able to import it to other wallets like Electrum

I just checked and yeah based on his post history he already asked this many times but he doesn't do anything. It seems that he doesn't care about the responses or he might have color blind sickness(black color vision deficiency)
