This is still one of my pet peeves regarding Electrum... that it defaults to mBTC as the unit to display the balance  someone should create an issue on github and complain about it. idk why they keep sticking to this default. |

The issue is that the button remains red(botom right on console) and there is no chance of connecting with what ever network is required to make a transfer. I presumed this was because my platform is too old now, or, is it because the operating system on my computer is too old?? I just want to do one more transfer and then be done with Electrum wallet!
old versions won't connect. on 4.0.2 you can click on the red button and then uncheck select server automatically,right click on a server in the list and choose use server. try a few servers until the button becomes green. after that you should see your correct balance and you can use the send tab to send money. if you still can't connect then make sure there's no proxy configured when you click on the red button (or via tools > network). also make sure you are not using a VPN. edit: it would also be useful if you told us what OS you have. if it's win 7 then try the microsoft update mentioned at the bottom of the download page: https://electrum.org/#downloadif none of the above works then enable debug logging and pastebin the results: https://github.com/spesmilo/electrum-docs/blob/master/faq.rst#how-to-enable-debug-logginghttps://github.com/spesmilo/electrum-docs/blob/master/faq.rst#where-is-the-electrum-datadir-located |

so there are lots of contradictory things in this thread. you say the balance is correct but also say certain transactions are missing. it would be best if you simply created a new deterministic electrum wallet and sent all your coins to an address in that using armory. exporting and importing private keys can be error prone as you've discovered. |

So the question is how to delete a transaction in Electrum, so that a new RBF type is sent to a mempul but with a higher Commission so that it is carried out faster than the first, but not as now to the same wallet, but to another one, let's say
if the original transaction is marked as replaceable (this is the default behaviour in electrum) then simply right clicking it and choosing increase fee, choosing a higher fee and then clicking ok and then sign and broadcast in the next window should do the trick. |

there's a share icon on the request screen on electrum android. it looks like 3 points with paths between them. you can simply use that to email yourself the address. then just pay to that using your PC.

Even if the checksum does not validate to true the seed can still be valid this is a requirement in the protocol.
As far as i can see the 6 word phrase should be used as the salt or password in conjunction with the 12 word Mnemonic.
the bitcoin protocol has nothing to do with seed phrases. a wallet wouldn't generate an invalid bip39 seed. what is the different between wallet.dat and virgin_wallet.dat and full_wallet.dat ?
how do you know the address of that wallet without downloading all bitcoin core ?
is there away to know what kind of wallet.dat is becouse i see etherum wallet and peercoin wallet and bitcoin-wallet-backup-2015-10-10 and Darkcoin-wallet-keys-2014-07-22
and Dash-wallet-backup-2015-08-23 and walletFTC ?
what is that ?
all files ?
how about you tackle one thing at a time? try restoring from the 12 word seeds using electrum like i said. |

I came across this address 1BitcoinEaterAddressDontSendf59kueTo generate a 1BitcoinEaterAddressDontSend address using VanityGen, you will need 3.3 E+33 or 3.3 decillion years. Please tell me how you can generate an address of this length and with what? Here is a link to the transactions https://btc.com/1BitcoinEaterAddressDontSendf59kuEor do I not understand something? vanity gen tries to generate both private keys and corresponding public keys that hash to an address with the prefix you want. that's why it takes so long because it's essentially a bruteforce effort. making an address where you don't care about the private key is relatively easy. it's just a large number with a checksum. |

electrum doesn't have a phone number. you likely have a fake version of electrum. i suggest you check your browser history for the exact download url. it should be download.electrum.org or just electrum.org.

If you need a fast way to check all the addresses, just copy/paste them into a new Electrum "watching-only" wallet ("File" -> "New/Restore" -> "Import Bitcoin addresses or private keys")... it'll find any/all transactions relating to those addresses and you'll be able to see which ones still have a balance. NOTE: - don't try and use the 6 word passphrases, that won't work in Electrum... just copy/paste the addresses. At least that way you'll see whether or not there is actually anything to find  I'm not aware of ANY wallets that used a 6 word passphrase... and because these 6 word phrases seem to be attached to one specific address, I don't think they are a true "seed mnemonic" for an HD/BIP39 wallet, but as mentioned earlier... I'd think they were some sort of "brain wallet"... or maybe some other custom system used to create private keys from words??? Given that the address from your screenshot: 1A9Tp3JjDvyQUtyQYLdDdCqMgK12sVZ238 is empty and has never actually been used, would you be willing to provide the 6 word passphrase for this address so people could try and figure out the system used?  or is it the same passphrase for ALL the addresses? and the 12 seed not working in elctrum it give me wrong address like this one bc1qc4fdk5re3r08msaelnndnywnh9pec5p5tqh9kv You must change the type of address to 'legacy', not segwit. the address have .1 btc but in electrum have zero ? start again as per this guide: https://bitcoinelectrum.com/restoring-your-standard-wallet-from-seed/pay attention to the what it says next to the options button in step 4. if it doesn't let you proceed then you can try checking bip39 under options. after you do that it should show bip39 checksum ok. if it doesn't then you have a seed that is neither electrum nor bip39 and you can't use it with electrum. then in step 5 select legacy as the script type. try the default bip44 derivation path and if that doesn't work then try the one for multibit hd: https://bitcoinelectrum.com/restoring-your-multibithd-wallet-in-electrum/ |

essentially the send and receive tabs don't tell you about transactions involving your wallet. you should only trust the history tab for that.

In electrum.org it says that hackers can hack the site and replace their own software that hides malicious code in the electrum software. It says that we have to verify the signature of electrum.org, in order to be sure that the software was not compromised. Now I'm asking, why are we 100% sure that they can't change his signature too? Also, by that tutorial of how to verify electrum I don't get why should I trust gpg4win.org, couldn't this site get compromised as well? And a bigger question, how exactly can you compromise a site?? Is this possible? Does google.com differs from electrum.org? Anyway, back to the point, I have reset my windows 10 laptop. I've downloaded from another laptop electrum-4.0.2-setup.exe and then I transfered it to a usb. The clear laptop (the one I reset) is not internet connected and it'll never be. I've verified the signature (same way, downloaded to my old laptop and transfered the file with a usb). Is this a purely cold storage? Can I buy a thousands bitcoins now without having the fear of losing my coins? digital signatures that are modified are no longer valid. they will not verify. gpg4win provides an easy to use gui frontend to gnu privacy guard on windows. its releases are also gpg signed so you can verify them. there are alternative software that you can use gpg itself or kleopatra which is cross platform. Is this a purely cold storage? Can I buy a thousands bitcoins now without having the fear of losing my coins?

This kind of problem normally occurs when the network is busy, try increasing the fee or target it to within 5 blocks so your transaction will confirm faster. -snip-
Nope II, it's a local transaction which wasn't broadcast to the network yet as already pointed by others.. twice. As the error message says the server does not know about it. It simply means the transaction is not in the mempool of the server you are connected to and neither has it been incorporated in the blockchain. You may or may not have broadcast it. It's possible for a transaction to be broadcast but not reach every node in the network. It's also possible that the server you are connected to knew about the transaction but ejected it from its mempool because it learned of higher paying transactions. |

ios version has been abandoned. I suggest restoring from seed on android or using a bip39 compatible PC wallet like copay.

Thank you all for the answers.
That's not "scam" LOL, as far as I know.
Some points that may make some difference.
I believe that 50 BTC's are old (very), at the time we can mine with normal GPU's.
I received these rewards and they were not propagated in the network correctly, they can be contained in my "wallet.dat".
Why when i make "getbalance" i saw all these BTC's ?
Sorry but i dont have knowlegde to solve this alone
Bitcoin transactions that are not recorded in the blockchain aren't really bitcoin transactions. You haven't received anything. It could be an altcoin wallet. All the bitcoin forks would have the same block reward though. |

electrum has a notify option which can tell a script about transactions relevant to your wallet. then your script can move your coins using electrum. type `electrum help` on the command line (linux,macosx only) or use the json rpc interface: https://electrum.readthedocs.io/en/latest/jsonrpc.html |

You have to select multisignature wallet, choose number of cosigners and signatures required and then "use a hardware device". This last step you repeat for each of the ledger devices. Then for the final cosigner you can have it generate a seed for you.

there was a wallet file corruption bug in previous versions. you may have been hit by that. i suggest starting over on a fresh PC. leave your current system untouched for reference purposes. restore from the private keys corresponding to addresses with unspent outputs (coins).
The problem is as mentioned above. I have only select private keys, the Addresses that Electrum made from who knows where, i should have included a link to the relevant github issue. the wallet file corruption bug results in wallets displaying addresses from a different seed/wallet. it requires you to have generated more than one wallet in a session and for you to have a dodgy drive. for example USB drives are disproportionately effected. https://github.com/spesmilo/electrum/issues/5082another possibility is that you simply have a watch only wallet. in that case it should say watch only in the title bar and under wallet > information. |
