It cannot. Electrum uses their own system for creating seed phrases which is slightly different to the BIP39 system. You can read their motivation for doing so here: https://electrum.readthedocs.io/en/latest/seedphrase.html#motivation. There are one or two wallets which will accept Electrum seed phrases, but the majority of wallets will not. However, the way Electrum turns seed phrases in to addresses is still common knowledge and very easy to do. Any piece of open source BIP39 software could be changed to work with Electrum phrases with a few very small modifications. You do not have to worry about Electrum ceasing to exist in the future and you having no way of restoring access to your coins.

You could use the above tool to extract the private keys to individual addresses and then use those private keys to sweep the funds, yes. There are also a number of other ways you could do this.

I would use an open source OS, such as Linux distro of your choice, rather than any version of Windows. Also make sure you format the computer before installing any fresh OS on it. If you can physically remove the WiFi, ethernet, etc. hardware rather than just disabling it, then even better.

I'm going to disagree with the post above and say that I prefer airgapped cold storage to hardware wallets. There have just been too many issues with hardware wallets in the last few years, from the database hack you mentioned through to unpatchable vulnerabilities allowing extraction of seed phrases, for me not to believe there are not other vulnerabilities or issues which exist but either have not yet been discovered or have not yet been disclosed. My feeling is that a properly set up, permanently airgapped device, using whole disk encryption, is safer than a hardware wallet, but I concede that such a set up is significantly more complicated than using a hardware wallet, and much more prone to user error. The side channel attacks mentioned are not high up on my list of possible attack vectors since my airgapped device is only ever used in a sealed room inside my house with no one else around, all curtains drawn, no webcams, etc.

Another big question to ask yourself is portability. There is no denying that a hardware wallet is far better than airgapped cold storage when it comes to carrying it around with you and transacting on the go.

You do not need to import either your addresses or your public keys. The only thing you need to import is your private keys - Electrum will derive the public key and the address automatically from the private key.

The wallet will be "unlocked" simply by possession of the private key. The public key and/or address are simply printed so you can look up your balance or deposit more coins to the paper wallet without having to expose your private key. The private key is all that is needed to spend the funds, and is the only thing you need to import to Electrum.

Well, that speeds things up a bit since you only have to check a single address type and (presumably) a single derivation path for each valid seed phrase. But you do still need to check, which requires something to check against. If you cannot find an address to check against, then your only remaining option (short of manually entering each seed phrase in to something like Ian Coleman and then manually copying the address in to a block explorer) is to use an address database. The link I have provided above not only gives instructions on how to create one, but also gives links to pre-created ones you can download. The BTC one is around 6 GB, so much preferably to downloading the entire blockchain and creating your own one if you aren't already running a full node.

So, the reason the transaction is not broadcasting is because you have 2FA wallet and you have only signed the transaction with your own key. You still need the second signature from TrustedCoin to be able to broadcast this transaction. You should have an authenticator app you set up when you first set up this wallet, yes? If you do, then what I would suggest is to delete this transaction (right click on "Local", then click "Remove"), and try to make the transaction again from scratch. You should get a pop up window asking for your authenticator code. Enter it and the transaction should sign 2/2, which will allow you to then broadcast it.

If you do not have access to the authenticator you set up, then you will need to restore your wallet from your seed phrase. Open Electrum, create a new wallet, select "Standard wallet", select "I already have a seed", enter your seed phrase, and then when prompted choose the option to disable 2FA. Once you have created this new wallet, create the transaction again from scratch and it should broadcast normally.

Can you open your Electrum wallet again, and take a look at the title bar of the window it is open in. It will say "Electrum 4.0.9 - YourWalletName", followed by some words inside square brackets [like this]. What words are inside those brackets? Does it say standard, does it say watching only, or does it say something else?

Do you see the transaction saved as "Local" like I said you might? When you double click on the transaction, what do you see in the top box titled "Transaction ID"? Can you paste the Transaction ID here if you have one?

Do you remember if the wallet was legacy (addresses start with "1") or segwit (addresses start with "bc1")? I don't think Exodus creates P2SH addresses (starting with "3"), but someone can correct me if I'm wrong.

Is it possible for you to find an address in the wallet? Perhaps you looked one up on a block explorer and it is saved in your internet browsing history? Perhaps you withdrew to this wallet from an exchange or other service, and you can find the address from your account history or from an email confirmation?

If you are unable to find an address, then you are going to have to build an address database (see my link above) so btcrecover can check every valid seed it finds for funds. If you know where your missing word slots in to your 11 words, then there are 2048 possibilities, of which 128 (on average) will product a valid seed phrase which needs to be checked for funds. If you don't know where the lost word slots in, then that becomes 1,536 seed phrases which will need to be checked for funds. Further, if you don't know the address type, then you will have to check multiple derivation paths for each seed phrase.

Not quite. It's not like you are directly trading with other users like you would in a decentralized or a peer-to-peer exchange. Yes, other users are placing buy and sell orders on the market, which you can see in real time and which will affect the price you pay for your market order or whether your limit order is filled, but you are still buying and selling to Coinbase rather than picking an individual user to trade with.

Think of Coinbase like a pawn shop. You go in, there is a product you want (bitcoin), you pay the price on the price tag, and the merchant (Coinbase) takes your money, some of which will be fees/profit. Or you may want to sell some bitcoin to them, and they will tell you the price they will give you for the bitcoin.

Think of Coinbase Pro like a stock exchange. There is a product you want (bitcoin), but the price is constantly moving up and down because thousands of other people are buying and selling it at the same time. Money is moving in and out. You can still just say "Here, take my money and give me some at whatever the current price is" (a market order), but you can also say, "I would like to buy/sell but only when the price falls/rises to X dollars" (a limit order). Even though there are thousands of people buying and selling constantly, all the trades still go through the stock exchange - you don't walk up to another random person on the exchange floor and hand them cash.

Coinbase is simpler but comes with higher fees. Coinbase Pro is more complicated, but if you know what you are doing you will save money by using it.

Did you ever see these funds inside your Electrum wallet before you forgot the password? Are you sure the addresses inside that Electrum wallet also started with "3"?

If the new wallet contains addresses starting with "1", and the old wallet contained addresses starting with "3", then you have recovered the wrong wallet. Are you sure this is the correct seed phrase? How did you create it in the first place? Did you generate it in Electrum, or did you generate it elsewhere and import it in to Electrum?

I'm not sure what you mean here? As in, it doesn't re-use the same word in the same phrase? As Exodus uses BIP39 seed phrases, and BIP39 makes no stipulation regarding word reuse, then this is not the case. Given a 12 word seed phrase, there is an approximately 1 in 31 chance that there will be a repeated word. This rises to around 1 in 8 for a 24 word seed phrase.

It needs either the master public key or an address from the wallet it is trying to recover, so when it finds a valid seed phrase it can check whether it is the correct one which generates the matching public key or address. If you have neither of these, then you can still run it, but you will need to download an address database (https://github.com/3rdIteration/btcrecover/blob/master/docs/Creating_and_Using_AddressDB.md) so it can check the addresses it generates against all address to see if they contain any funds.

I have lost count of the number of times I have provided him with links to full genomic sequences from literally tens of thousands different isolated samples of SARS-CoV-2 from all around the world, and yet he keeps repeating the same nonsense. He is either incredibly stupid, maliciously lying, or (most likely) both.

That address has only one incoming transaction for 0.00052451 BTC, which is several days old and is long confirmed. If you are trying to send this money out to another address, then the problem is as I said above - you have only saved the transaction locally and not actually broadcast it to the network. Here is how to resolve this:

Open your wallet in Electrum
Go to the "History" tab
Double click on the saved transaction, which will be called "Local [xxx.x sat/b]"
Click on the button "Sign" at the bottom right, and enter your wallet password when prompted if you have one set up
Click on the button "Broadcast" at the bottom right

No offense taken.

I see no disconnect between advocating for users to take their privacy seriously and reporting users who are evading bans or similar.

So everyone must stop using exchanges? What about trading peer-to-peer? Only freshly mined bitcoin are safe?

What rules and regulations which invade privacy have I advocated for?

When you look up the address on a block explorer, you can see your funds on it? What character does that address start with? 1, 3, or bc1?
When you recover the wallet from your seed phrase, do you see the addresses with your funds on it (even if it shows up as empty), or is your address not there at all? What character do the addresses in this new wallet start with? 1, 3, or bc1?
At any point do you remember using a passphrase or extending your seed phrase with additional words?

This old chestnut again?

No, it isn't. It makes up about 8% of their business: https://bitcointalk.org/index.php?topic=5276433.msg55214460#msg55214460

I used blockchair's database, which is pretty comprehensive and lets you search for all kinds of things.

In this case, go to blockchair.com and scroll down to click on "Bitcoin explorer". Then in the menu on the right, look for the "Mempool" heading and click on "Outputs". You will then be met with a list of all unconfirmed outputs (around 1.3 million at present), and a bunch of fields at the bottom to help your filter this list. In this case, I used "Value (BTC)". Click on the filter icon (looks like a funnel) beside that field, and in the top box entitled "Value (BTC)  ==  _____", enter 52451 and then press the "+" symbol to add the filter to the search results. This left me with two transactions:

https://blockchair.com/bitcoin/address/3A7TrACSPFFySYVF1PNc74HgXebDkW4AC7
https://blockchair.com/bitcoin/address/bc1q6naqw6d433gf837wcks07m6ahchsqdkxk9meqx

The field under the "Value (BTC)  ==  _____", which looks like "_____  <=  Value(BTC)  <=  _____" allows you to set a range. So if you put 1,000 in the first box and 5,000 in the second, it would filter all unconfirmed outputs with a value between 1,000 and 5,000 sats. You can also choose to add or remove fields from being displayed by checking or unchecking the first box, or choose to sort by any field (descending or ascending) by selecting the circles with the down or up arrows, respectively.

From the main menu on the first screen, you can also search and filter blocks, confirmed transactions, confirmed outputs, and addresses, as well as unconfirmed transactions and outputs still in the mempool.

I can find two unconfirmed transactions which include inputs of 0.00052451 BTC. One pays 20 sats/vbyte, and the other pays 8 sats/vbyte. This puts them approximately 6 MB and 30 MB from the tip respectively. The former may confirm over the weekend, the latter is very unlikely to do so. One has RBF enabled, and both look like they have change outputs so could be boosted using CPFP. If you are happy to share your transaction hash with us, then we can give you more specific advice about how to speed up your transaction.

The other possibility is that you have created a transaction in Electrum and only saved it locally rather than broadcast it. Doing so will still show up [-x.xxxxxxxx unconfirmed] at the bottom despite the transaction not being broadcast. If this is the case, simply double click on the transaction which will say "Local [xxx. sat/b]", make sure you are happy with the fee, and then sign and broadcast it.

The link above is probably your best bet, but there is also this program which you could use: https://github.com/3rdIteration/btcrecover

Do you remember what software you used to create the seed phrase? Are you sure the other 11 words are in the correct order? Do you know the position of the missing 12th word?

Even if the answer to all of those is no, you should still be able to brute force your last word, but with additional information you can reduce the search space and therefore the time required.

So, minor correction. The command you have given doesn't actually increase the gap limit. What it does is simply generate and display the next 50 or so addresses beyond the last address in your wallet, without paying any attention to the gap limit. Addresses which it generates which are beyond the gap limit will show up with a red background.

If you want to actually change the gap limit, you would use the command:

You can change the value of "50" to any value you like. If you decrease the gap limit from what it currently is, you will need to restart Electrum before the extra addresses disappear from your "Addresses" tab.

You can also use the following command to view your current gap limit:
