As per usual, you should share armorylog.txt from Armory's data directory.

Without the logs, try to use the usual troubleshooting for "offline" issues: Armory might be looking at the wrong satoshi directory (bitcoin's data directory).
This happens when you set a non-default data directory in bitcoin core and didn't set Armory to find that directory.
You can set it in the "File->Settings->Blockchain and Database Paths", under "Bitcoin Home Dir".

If it's offline, it won't be able to scan for transaction history.

You have the option to export the private keys but since you already got the full blockchain, you might want to finish setting-up Armory instead of importing the keys to a less secure/private client.

If you read the previous posts, you'll see that the problem was: he misunderstood Electrum's receive tab, there's a "request amount" there and he probably mistook it as "Buy Bitcoin".
Never replied after his third so I think he figured it out because of Charles-Tim's answer.

The "huge space" must be caused by the muscle memory of pressing "Enter" to send but he didn't know that the forum added break-lines instead.

Electrum's "Increase fee" has only the capability to create a replacement that'll send to the same output(s) or back to self through "cancel (double-spend)"

That said, "Cancel (double-spend)" option will replace the output with one of your wallet's unused address.

Is your Seed BIP39 or created in Electrum? (the wallet info in the screenshot is showing "watching-only").

If it's Electrum seed, I'd not bother including the derivation path because Electrum will automatically select the correct derivation path during the wallet restoration process.
The path is already defined in the seed in the form of "version": https://electrum.readthedocs.io/en/latest/seedphrase.html

In case it's BIP39, I'd put the derivation path that's displayed in the "Script type Derivation path" window
and a short list of selections like "Standard->I already have a seed->Options->BIP39 seed" in order for the backup to be "ELI5".

I hope that you have a backup of the unencrypted wallet.dat.
Because by encrypting it while it's not synchronized, the keys for addresses of the transactions that still not saved by the wallet will be flushed and be replaced by new ones.
That may be the reason why you're getting 0 balance in your new laptop.

Try to export the unencrypted wallet to the new laptop instead and let it rescan.

Problem is, that year-2015-transaction should've been already verified with your current block height, are you sure that it's Bitcoin Core's wallet.dat file?
Because you can paste an Altcoin wallet.dat file to Bitcoin core and it will display the previous unverified transactions as Bitcoin until it sync.

In blockchain.com (that's not "the blockchain" BTW) if the address can't be found, it means that it's invalid, not a Bitcoin address;
if it shows 0 in and outs, it means that it's valid but didn't received any transaction yet.

The previous posts are true based from the RBF rules,
but take note that there are clients that will not let your perform RBF if the transaction has a child.

One big example is Bitcoin Core GUI (bitcoin-qt), once your transaction has an unconfirmed child in your mempool, it wont let you select "increase fee" option.
bumpfee wont also work, but it's still possible to manually create a replacement transaction using commands.

They didn't disclose the units in the result of getnetworkinfo but it's in "BTC/virtual kB" on both "relayfee" and "incrementalfee".
That's equal to to additional of +1sat/vB of the original transaction.
When you use the help command for help getnetworkinfo, it'll display the units for those results.

Yours didn't worked maybe because the "absolute fee" is short of a few satoshi to actually reach the minimum of +1sat/B additional fee (like explained by hosseinimr93).
Or if it has an unconfirmed child(ren) transactions, the replacement transaction should be able to pay an additional fee equivalent to the children's "absolute fee" aside from the previous requirement.

Always keep a copy of your seed phrase on a paper stored in a safe place like a vault, that alone can restore your funds in case of lost/broken device.
Do not save it in the same device, online or cloud  storage, or anything that's connected to the internet because of the reason above.

As per security measure, it's a mobile device so it's not recommended for hodling Bitcoins for a long time.
I wouldn't recommend any mobile wallet for that purpose at all unless you won't use that phone.

It's off-topic BTW, next time, please create your own thread if it's not related to the topic.

You must be pertaining about Electrum's "Receive" tab.

Just like others' said, you cannot buy Bitcoins through Electrum directly.
More info for the receive tab: The requests you created using that tab only act as "invoices" so Electrum will know which addresses will be funded so you wont accidentally reuse an address for privacy reasons.
It'll also automatically include the description you input to the history tab when the invoice was successfully paid.
They have expirations because of the same reason so the address for the (unused) expired invoice can be used for a new invoice.
The tab is basically where you request new address to receive Bitcoins.

You can read Bitcoin articles about "difficulty" and "target", the easiest source is the Bitcoin Wiki: https://en.bitcoin.it/wiki/Difficulty | https://en.bitcoin.it/wiki/Target
Disregard the "pool difficulty" parts since it's talking about pool mining.

Basically, if the total network's hashrate is lower, then in the next "epoch", the difficulty will be lower; vice-versa.
More comprehensive details in the link.

Is there any difference if the wallet was created long ago?
Because based from the context, it sounds like newer wallets are harder to crack compared to old ones.

Always base it on that "50% in <n>d".
In your case, It may take more more than 2 to 5 days or if you're lucky, within a few hours if you're lucky.

"bc1qtapr00t" has a quite low difficulty of 34359738368 with VanitySearch (Official Thread link).
That'll only take a few minutes using a modern Nvidia GPU or about an hour with an Intel 4th Gen processor or equivalent.

What I'm saying is, paying $100+ isn't necessary.

Sample (please don't use):

That site doesn't represent the majority of the node's mempool and there's no related changes in the code after April 2021: https://github.com/jhoenicke/mempool/commits/master
So maybe he just started accepting <1sat/B transactions or lower his previous setting (minrelaytxfee=n BTC/kB) and for some reason, they never left his mempool since.

Or a bug perhaps?
Maybe it has something to do with the changes he did in the default fee level: https://github.com/jhoenicke/mempool/commit/cffef45b49fc233664d2e735b9f30b1c0016b7c6
Forcing it to zero might have resulted with that graph.

No problem.

Custodial service-related issues can be posted in this board: Bitcoin Forum > Economy > Marketplace > Service Discussion
If you got further concerns or updates, you can create a thread there.
They've also got their own thread in Gambling board: https://bitcointalk.org/index.php?topic=320959.17000 (link to the current last page)

This thread is dead and and OP hasn't logged-in since November 12, 2019.
If you found other direct links to Claymore Ethereum GPU Miner, that's most likely a malware.

The problem I described is if you haven't changed the default withdrawal address in your profile.

Otherwise, you can follow the second option in their instruction which I believe any address you've used to deposit bitcoins to your account.
I can't quite figure out "or an address you previously deposited from" but it seems like the address you've used in your previous deposits, there's no other addresses a user can sign anyways.

Anyways, if you've deposited before and can't recall the address used, you can open their deposit page:
"Profile->Deposit" and there's a list of "old deposit addresses" below that window.
You can paste them to a blockexplorer to check for a transaction that looks like your previous deposit and take note on the input(s).
If it belongs to the wallet you used to deposit and it's non-custodial, you can try to sign a message using that address.

Can you still open Copay when you restore a backup of the iPhone? It's okay even if it can't connect to servers.
It's old and these might not be accurate but try to export an offline backup:

• Tap settings icon and then tap the wallet name to open wallet options.
• Tap "More options" and then "Export Wallet"
• Type your password and your backup phrase should show up or exported into a text file depending on your selection.

If Copay isn't accessible, I can't help any further.

The backup should be your "recovery phrase",
I don't how many words BitPay used when it was CoPay but it should look like a random set of words consisting of 12 or 24 for standard phrases, sometimes more or less.

I'd rather not answer with an estimated time of arrival since mempool is unpredictable, but I'd say 2.7 or 1.3 sat/B are a bit low even for a normal priority fee.
If more transactions are added, it may take days or weeks, if vice versa, the next hour or so.

With the current standing, you can go as low as 7sat/B and it will still be cheap as long as your transaction isn't large in size (not the amount to be sent).
The (virtual) size of the transaction heavily depends on the number of inputs it spend and their (script) address types, quite affected by the number of outputs.
I believe that's already explained in the OP of this thread.
