Dabura667 is right on the money as usual. However if you want to make a larger seed (like 256 bits) you *can* do that. The make_seed command line option will generate larger seeds: |

Why do you want to send all the bitcoins to one address? There is no benefit to it.

HA! Excellence, I found the wallet.dat file thanks to you. Now what do I do with it?
Lol, if this results in bitcoin, I'll send you a tip!
Did you find this file on your hard drive or the USB drive? When you run bitcoin qt on a computer with no wallet it will create a new wallet for you. So if you found it on your hard drive after you ran the bitcoin qt program on the USB then it'll be a new empty wallet. |

No because floppies are notoriously unreliable. You just got lucky with those particular disks.

Perhaps run a for loop? In bash on linux: dest_addr="1somethingsom" #destination address from your wallet
for privkey in `cat my_list_of_keys_one_per_line`
do
electrum sweep $privkey $dest_addr
done

You can set a password using the wallet menu > password option. Note that the balance and transaction history will always be displayed regardless of whether you set a password or not. The password is only necessary when spending your bitcoins. At that point it will ask for the password to decrypt your seed and sign the spending transactin.
If you want privacy for your balance and transaction history then use the user account feature of your operating system. Create a separate user account for other users so that they don't bump into your stuff.

With the electrum multisig I made a wallet, but I can't restore it with just 2 pieces of information. It may be 2-of-3 in terms of signing the transactions, but is it 2-of-3 in terms of restoring the entire wallet?
It should be 2 seeds and 1 xpub. That should be enough to restore the wallet. Ok so I just tried it and this is exactly how you would restore if you didn't have all the seeds. 2 seeds and one xpub. If you have just one seed then 1 seed + 2 xpubs would create a watch only wallet. Also the commands on the website initially didn't work for me with electrum 2.6. I had to add the options after "make_seed" for it to work.
So "electrum --nbits=256 make_seed" had to be changed to "electrum make_seed --nbits=256"
and "electrum --entropy=123456 make_seed" had to be "electrum make_seed --entropy=123456"
maybe double-check and update the webpage?
Thank you for that. I've corrected the page. |

I do see the correct bitcoin address on the first line of outputs though which showed the exact amt of btc i sent to that address. So that means i sent it to the right one correct?
Yes. Adjust the fees in the electrum preferences window so that transactions confirm faster in future. You are a very high maintenance electrum user  Do you have to create so many threads? Try figuring things out on your own for a change. Read the docs. |

For OmegaStarScream and others who don't understand what's going: This is a legacy feature from back when Electrum wasn't HD. Back then seeds were generated differently and one encoding of them was in hex. To rogertb obviously this is not working how it should. I don't think it is wise to rely on this old feature for a new electrum wallet. It has only been included for backwards compatibility with old wallets. Electrum does have native m of n support. It's called multisig. I suggest using that instead. If for some reason you need to create your own custom length seed then use the command line option for that. The new type of seeds cannot be crafted by hand. They have a checksum in them so it requires a computer to do it. |

Its donations for some of the coding that I do. Yes, the donations are small but they add up. Where can I find a wallet that consolidates the inputs into 1 output?
To sweep dust you need to raise transaction priority. Transaction priority is a function of the age of the inputs and the size of the inputs. If you want to spend the dust you can either wait for the inputs to age a lot. Say a year or two. Or you can include a larger input in your transaction. So I suggest sending yourself 1 or 2 BTC to an address in your wallet, waiting a few days and then sending all the bitcoins including the dust transactions to another address in your wallet. The 1-2 btc input will push up the transaction priority and you won't have to spend as much in tx fees. |

Is it possible to set up a multisig electrum wallet and also do regular transactions, on the same wallet? Or would I have to have a second electrum running on a virtual machine or something like that? I wish electrum would enable multiple accounts on the same HD wallet, like mycelium does. That would be very useful.
You need different wallet files, but there is no need for a VM. You can open several electrum wallets at the same time. Thanks. How do I create extra wallets after setting up the first one? Do I have to import them from another device? I haven't seen that option in the menus before, but I haven't used electrum in awhile. file > new restore file > open |

-snip- Great help, thank you, so thats why it is always best to use a new address for sending and receiving Bitcoin  But its wrong!. Bitcoin core keeps (by default) 100 unused private keys and addresses pre generated for you. This would only work if you would use all 100 (change)addresses. Yeah exactly. You would need to exhaust the keypool and then send the bitcoins to a new randomly generated address for your old backups to be worthless. It would actually be safer to just let core generate a new wallet for you. It will do that if it finds there is no wallet.dat file in the data dir. Then you send your bitcoins from the old wallet to the new. |

Yep they probably could if they took it while you are sending bitcoins. In the process you would have to enter your password and for a while that would be in memory. Electrum uses python so it doesn't have the low level hardware access that say bitcoin core does. Core can scrub the memory after its done while electrum probably can't. It has to rely on the OS to do that.

I suggest that you backup your wallet file instead of relying on the seed to restore your wallet. The reason is that seed will not contain the labels for your addresses and transactions that you've entered in your wallet file. However, restoring a backup of the wallet file will restore the labels too.
To create a backup go to file menu > save copy
To open the wallet file after resinstallation you can use the file menu > open command.
I would have loved to know this before  . I've kept a copy of the data that was in the Roaming folder, will I be able to keep the labels with it ? Yep. That's exactly where it's stored: http://docs.electrum.org/en/latest/faq.html#where-is-my-wallet-file-locatedSo all you have to do is restore the Roaming folder and install electrum. It should pick up your wallet file automatically. |
