Because HTML is quite simple and a scammer who want to display it above the page can easily edit the source code and make his own site.
Here's an example (it's in dark-orange theme BTW):


Your screenshots are inconsistent, one is from the older version and the other is the latest.
Why's "inspect" opened in the other screenshot, accidentally hit F12 instead of PrtScn?
There are 445 errors in the page with "inspect" open.

IDK what you're into but Bitcoin users and even developers have no access to anyone's bitcoins, there's no way to do a "Btc recovery" in a way of granting non-spendable balances.
Whatever the situation is, there absolutely no way that it's legit.
Come to think of it, why would someone gain $500k for sending $2000? Even contest/lottery winners wont be asked for any amount to claim their price.

Electrum has its own script to build libsecp256k1, the version for your OS might have a missing module.
Try to use:Or the other workarounds mentioned in this post: https://github.com/spesmilo/electrum/issues/6465#issuecomment-691368241

But I doubt that it will fix the other issue since there seems to be a problem with pyqt5 when you use the Appimage.

From the discussion, it's still not certain that you've downloaded a malware version of Electrum.
And the transaction is just recent, if you've installed the malware version before, the funds should've spent the moment you typed your password.

How certain are you that no one seen your seed phrase?
Where is it stored? Written on a paper in a safe storage, a device which is connected to the internet or somewhere online like a cloud storage?
Only the former is the recommended and safest way to store the seed phrase, the other two have a great chance to get hacked.

The transaction is already confirmed: c1fe9a5e07b0e1663fbaac996f31465b05109b29c4b7b004842de40cf4f7e0d5
There's no way for your to reverse it.

Now, if 1JMW9BuQrAPpvqRyBAcLE37ePQxaXsR7SJ is your "change address", the rest of the balance (0.00706326 BTC) should be added back your bitcoin.com wallet balance because the change address is used by your wallet to receive the excess amount of the transaction.

Isn't that the watch-only wallet?
Then he didn't actually update the balance of the offline wallet.

And copying the watch-only wallet wont affect the cold-storage Electrum since it's basically the same as transferring transaction files between devices through USB.

Transaction saved in the wallet.dat will still be displayed once loaded to a non-synced node.
The difference is: they'll be temporarily marked with '?' since they may be invalid until the node sync to the height where the transactions were.

So, there's a chance that it's really Bitcoin unless the wallet.dat is from "Litecoin Core" or "SegWit2X Core" clients because "Bitcoin Core" will display them as Bitcoin even though they're not.

@nadeto3719 you can get the transaction IDs of those transactions from the 'Transactions' tab by using "right-click->Copy transaction ID" and paste to a multi-blockeplorer to know which coin they belong to.
For that, use https://blockchair.com/ for Bitcoin and Dash, i don't know any blockexplorer for the dead coin SegWit2X.
If it's Bitcoin, the best and safest way to go is to let Bitcoin core sync.

ranochigo's reply is the only way AFAIK.

My method to keep the air-gap electrum's balance in the history up-to-date is to save every transaction that it signed before closing the window
and also save transactions from the watch-only wallet that I haven't spent yet. But there's really no reasonable reason to do that aside from my OCD.

If you want to follow ranochigo's reply but there are too many transactions in your history, you can just export-import the entries in the watch-only wallet's 'coins' tab (View->Show Coins).
You might need to increase the cold-storage Electrum's gap limit to be able to save the transactions that used addresses beyond its gap limit.

• In the offline Electrum, open console and type wallet.change_gap_limit(1000) (increase "1000" depending on your expected wallet usage), then restart Electrum.
• In the watch-only Electrum, open coins tab, right-click a UTXO, select "details" and use "Export" menu. Do that to all of the available coins.
• Back to the offline Electrum, import them using the menu "Tools->Load transaction" and click "save" to save the txn locally in the history.

With the same number of coins, the balance that's displayed in the latest transaction should be your current balance (not on the lower-left).

To maintain the correct balance, you can copy the "method" I've mentioned.

Please create your own thread when asking an off-topic question.
To do that: go to the board where you want to post (eg.: Bitcoin Technical Support)
and click "new topic" at the right-hand side of the screen (at the top of the topic list).

Now, to answer your question:
[1] I suppose it's Bitcoin core, then '?' are transactions that has various issues, most of them are txns that already dropped from your mempool.
To "clear" it (you mean remove?), you can use "Abandon transaction" when you right-click the transaction in the 'Transactions' tab, you should be able to reuse the inputs that it's trying to spend.

[2] This doesn't make sense, if you send to an address that's used for mining reward, it will be sent "normally" and prioritization will be based from the fee rate just like any other transactions.

If you have further questions, include it in your thread.

So, the issue is not block generation then.
"socket recv error Connection reset by peer (104)" is a generic error message which doesn't really tell the reason for the disconnection; it's usually followed by the description of the issue.
"29032 refused connection" may be an RPC problem connecting through port: 29032.

I'm sorry but I can't help you find the root of the issue,  you know your coin's code better than anyone.

IMO it's indeed a bit confusing because there's no numbering and detailed steps on creating the the "offline wallet".
Basically, the steps are:

• Create a new wallet with new seed on an offline machine.
• Get its "master public key" and use that to create a watch-only wallet on the online machine.
• The rest of the steps demonstrate the transaction creation, signing and broadcast process

Okay so it wouldn't be a very huge amount, if it's something you can risk, a Hot wallet on a "very secured" system will do.
Or consider getting a reputable hardware wallet from its official source (more info in this board: Hardware wallets).

I second this.
And [off-topic] proceed to give you a merit but it seems like it was double-sent, I thought it's not possible :/
-edit- I've accidentally pressed "prev" button and sent a merit again after a few minutes thinking that I still haven't.

@2140Miner With that amount, I'd suggest you to create a "cold-storage" set-up, here's a tutorial on how to set-it-up in Electrum:
https://electrum.readthedocs.io/en/latest/coldstorage.html
The screenshots are bit different than the latest version but the buttons/menu should have similar names.

Oh, right. Shame that I missed that.
Guess I'll just delete my reply to that post since it's not a genuine question.

I think it's unrelated, that issue started in v0.21.1 while OP's started in v0.21.0.

On top of that, incoming transactions with multiple outputs that belong to your wallet will be displayed in separate entry per output and will only display that one address on 'recent transactions'.
Only those "send&receive" transactions (with in/out arrow icon, 'send to yourself') are one of the examples that still lists multiple addresses.

Most tx from Nicehash are just 7kB, about 6.8kvB in virtual size, 7MB wont even fit in a block.
But still, it's really weird that the problem only occurs when you receive transaction from them.

Fortunately, I think you have fair chance to recover it as long as it's a BIP39 seed and you haven't restored it to a fake wallet.

Try Electrum: https://electrum.org | Verify its signature: /index.php?topic=5240594.0

To restore your wallet, use these selections when creating a new wallet:

• Standard wallet->I already have a seed->Click "option", tick "BIP39 seed"->Paste the seed phrase->next
• When prompted to select a wallet type, select depending on your previous wallet's address type:
  "legacy (p2pkh)" for addresses that start with '1', "p2sh-segwit (p2wpkh-p2sh)" for SegWit addresses that start with '3' (<- I bet it's this one) and "native segwit (p2wpkh)" for 'bc1' addresses.
• If you're not sure, you can create three separate Electrum wallets with three different address types and see if which one will come up with balance.

I don't know any wallet for IOS named "Bitcoin Wallet" aside from the one "for Android", anyways
some wallets use non-standard derivation path so you need to research the term "[N] wallet derivation path" if you fail to restore the right addresses.
Electrum wallet's derivation path can be edited in the address type selection window.

Somewhat understandable, at least the transactions of 3LXFcCGTmWWeqJ5oQMx6eVsSRj1Qx8xwME matched up to the statement.
The first and last transactions look like withdrawals from an Exchange (because of the inputs):

• "Satoshi-test" = 616487461a1afa595dfea8c20efde6b4cbdb3a7d7e058d810b029265e475f6b1(vout0)
• "Test amount" = faa8886508f0e724c0e2917fb0b47e0b732c2e8cf37278703dc80830208c8821 (vout4)
• "Transaction of XX Bitcoins" = faa8886508f0e724c0e2917fb0b47e0b732c2e8cf37278703dc80830208c8821 (vout3)

The latest transaction dated May 5 looks like batched, it seems to have included your last two withdrawals but it's missing from your personal wallet's history and balance.
If this is the case, you can only see the transaction from April 20 which was already spent, so your displayed balance is '0'.

But I suppose you still have the "personal wallet" in your device?
You're lucky if it's a non-custodial wallet where you can export the keys needed to export the funds to a working wallet.

TL;DR: Saying the wallet's name is good enough info to tell why the balance is missing and if it's recoverable.

You can get help for free if you can provide the necessary info, try to answer these:

• Do you know how many cosigners your Multisig address has and how many signatures are required to be able to send transactions?
  That's usually labeled as 2-of-3 multisig or 2-3 multisig, where '2' is the number of required signature and '3' is the number of cosigners.
  Because if either of the info is wrong, the addresses that you'll restore will be different.
• Do you have enough seed phrase(s) or master private key(s)? You need to have at least the same amount as the "required signatures".
  If you have, do not share them to anyone.
• Do you have enough master public key(s) to fill the number of cosigners used to create the MultiSig address?
• What wallet/website are you using?
  Depending on its setup and/or "keys" you have, you may be able to re-create it to a wallet that supports MultiSig.

I'm not available for private chat if you would ask, BTW.

Me too.
Jokes aside, there are local boards below the homepage: https://bitcointalk.org/index.php#5 (Local)
You can use your local language in your local board, if there's none, you can use: https://bitcointalk.org/index.php?board=11.0 (Other languages/locations )

Maybe it's time to check for possible hardware issues since you log seems normal.
First check the disk drives, RAM and then the processor.

It looks like a bug.
It's not just in Linux, I also upgraded to v0.21.1 (from v0.21.0) and it has the same issue on Windows10.
If there's a transaction with multiple recipients like a "Payment to yourself" transaction with 2+ outputs without labels, the window will expand to all of the addresses' full length.
I'm having the same error when trying to add a label too, other 'payment to self' transactions with label are editable.

Here's some screenshot from RegTest:
version 0.21.0 (normal):

version 0.21.1 (with issue)


That's just the previous release so there are only few PRs that may have caused the issue.

This doesn't sound like Electrum at all. From where did you downloaded Electrum?
The wallet should be created after setting up your wallet's password, there's no "full page of address" that will be displayed.
