Is the transaction confirmed? If it is confirmed, you cannot attempt to double-spend it.

If it is unconfirmed, then you can attempt to double-spend it.

What wallet did you use to send the original transaction?

Shouldn't be tooooo bad then... your transaction size will end up being something like 900-1000 bytes.... at around 400 sats/byte "recommended" fees... you're looking at fees of around 0.0035 to 0.004 BTC.

You can probably do it for less using a transaction accelerator

Honestly, you're just making more work for yourself unnecessarily... but whatever floats your boat.

If you choose to ignore the fact that Electrum will do pretty much ALL of this automatically, then go right ahead and do whatever you want...

Honestly, if you're desperate to test all this out... load up Electrum in Testnet mode... v3.0.3 installer creates a "Testnet" start menu item. Get some testnet bitcoins from some testnet faucets... and practice with Electrum without worrying about losing any money if you mess up.

or give me a testnet address and I'll send you a couple of coins

As long as you take backups of the wallet.dat's (put them on external storage like USB drives for extra safety)... you should be able to recover from any "mistakes".

What makes you think that someone else has your private key anyway? Did you type it into a website or something?

Errrr... you're misunderstanding how it all works... UNSPENT is GOOD! It means the funds have NOT been spent since they arrived in your wallet!

The transaction is "confirmed" which is also good... it means the transaction has been recorded in the blockchain and the funds have been received in the receiving addresses.

There is absolute NOTHING wrong with your transactions, the funds were sent and confirmed... you'll notice how the balance of both addresses are equal to the funds sent. You should see them in Electrum.


When you finally send those coins to someone else, they will change to "SPENT"... but until then, they will stay as "UNSPENT".

A slightly complicated way to go about this, but should guarantee no-one has your private keys (unless your entire computer is compromised)

- Shutdown Bitcoin Core
- Backup your wallet.dat... rename it wallet.old
- Restart Bitcoin Core to create a "new" wallet.dat with new addresses/private keys
- Generate a receive address
- Shutdown Bitcoin Core
- Swap the wallets again (wallet.dat -> wallet.new, wallet.old -> wallet.dat)
- Restart Bitcoin Core
- Send your BTC to new address
- Shutdown Bitcoin Core
- Swap wallets one last time (wallet.dat -> wallet.old, wallet.new -> wallet.dat)
- Continue using Bitcoin Core with your new wallet

This way, you're guaranteed not to accidentally use your OLD key again (but you have access should you ever need it)... and no-one should have access to your new keys.

I downloaded v3.0.3 yesterday... tried to run it... Windows popped up a big red box saying that it was blocked... Something about it not being signed software... Defender and MalwareBytes both detected nothing... I verified the digital signature of the file using GPG and signature... Re-ran it, and clicked the "proceed anyway" button on the big red warning box

I assume the warning was because it wasn't a "windows" signed application... probably requiring payment to Microsoft

Then just don't mess with Electrum and let it do it's thing... it will automatically take care of handling change addresses and fully spending coins sent to an address. You're over-complicating things for yourself and worrying about things you don't need to.

Just remember to give out a new address every time someone wants to send you coins. Some services don't allow this, there is nothing you can do about it. But at the end of the day, it isn't going to break anything.

Then your Bitcoin Core is not configured to download it elsewhere... Did you start it from Armory? or did you start it manually?

Either way, it's "datadir" path is wrong if it is not downloading where you wanted it to.

What wallet did you use? without that last character... the address is invalid and the transaction should have been rejected! If your wallet did not reject this address, it is BROKEN and should NOT be used!

Without seeing the details of the transactions... we will all just be speculating on the cause for your transaction getting stuck.

The most likely cause is (relatively) "low fee"... The Bitcoin network is super busy at the moment... 100,000+ unconfirmed transactions pending. As such, fees required for quick confirmation times have skyrocketed... "recommended" fees (https://bitcoinfees.earn.com/ and https://btc.com/stats/unconfirmed-tx) are now in the 350-400+ sats/byte range.

Any transaction with a fee less than that will likely be delayed for an indeterminate amount of time.

Other causes could be spending from unconfirmed parent transactions. Child transactions cannot be confirmed until the parent is. If you have received coins in a transaction that has not been confirmed, and then attempt to spend those unconfirmed coins, then your transaction cannot confirm until the incoming one does. Likewise, if you're spending change from an unconfirmed transaction, it can't confirm until the parent transaction does.

btcrecover (https://github.com/gurnec/btcrecover) by gurnec DOES work with backup files from Bitcoin Wallet for Android:



It also supports seed recovery for Bitcoin Wallet for Android:


So, you should be able to use either or both of the scripts on your "bitcoin-wallet-backup-2014-09-26" file.

Read the "quick start" guides (including installation) here: https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#btcrecover-tutorial
and here: https://github.com/gurnec/btcrecover/blob/master/docs/Seedrecover_Quick_Start_Guide.md

Your transaction still has not propagated well? It isn't showing on any blockexplorers, I'm guessing the 1 sat/byte fee ( ) is probably the problem!

Unless you can RBF that... which would probably break your big transaction, then you're going to be waiting for a LONG time to get this sorted.

Same minute and same second? Most likely an automated script monitoring compromised addresses... it waits for a suitably large transaction and then forwards it to the address belonging to the thief with a LARGE transaction fee to make sure it confirms ASAP. It looks like your wallet or your computer is compromised... you need to verify the wallet that you downloaded to rule that out.

Did you download the standalone, the windows installer or the portable version?
Are you 100% sure you downloaded from here: https://electrum.org/#download

There are a number of "fake" Electrum websites which look identical! The ONLY way to be 100% sure that you have the legitimate file, is to check the digital signature of the file by using GPG and ThomasV's signature.

Firstly, I would recommend that you upgrade Electrum to at LEAST v2.9.3 (for Windows 7/8 or earlier)... and v3.0.3 (Windows 10, Linux or OSX)... (do NOT try and use v3 with Windows 7/8 or earlier, it probably won't work!)

Then you run Electrum and if prompted to create a wallet file, select "Standard -> I already have a seed".

If you're not prompted, and it opens up into the application, you should use: "File -> New\Restore -> Standard -> I already have a seed."

Once you are at the seed entry screen, input your 12 word seed, select a new password, and your wallet and all your transaction history and addresses etc will be regenerated!

No, you need to go to the "Addresses" tab FIRST... right click on the address you want to spend from and select "spend from"... this will then populate the "Send" tab so that ONLY the coins in that address will be spent (you'll see a "FROM" box with just the inputs in that address and you'll notice the max amount is NOT your full wallet balance).

Then you put in the address you want to send to, and the amount you want to send... and the fee you want to use.

Bear in mind that doing this will create a chain of unconfirmed transactions... and there is NO WAY this transaction can confirm, until the inbound transaction is confirmed.

Are you attempting to do a "Child Pays For Parent" (CPFP) transaction?

If you uncheck "select server automatically", click on the "Server" tab and then manually put in a server like electrum.hsmiths.com (port 50002) or node.arihanc.com (port 50002) etc... and then restart does that do anything?

Also, it looks like you're running an old v2.x version (I assume older windows?)... is it v2.9.3?

I wonder if it is possible, that when you originally set it up, you went to the seed entry screen and then clicked "back" to go back to the seed display screen... when you do this, it will generate a new seed!

So if you had taken a screenshot, then clicked next... then clicked back to look at the seed again... it would have generated a new seed different from your screenshot.

You'll also want to upgrade to the latest version of Armory from here: https://github.com/goatpig/BitcoinArmory/releases

Get the v0.96.4 RC1 (aka v0.96.3.99) release if you are using the latest version of Bitcoin Core (v0.15.1)

Because that hasn't been the official download location for a long time now... the original bitcoin armory "company" essentially folded (https://bitcointalk.org/index.php?topic=1351792.0)... goatpig took over development.

The NEW website is: https://btcarmory.com/
The very latest code is available on goatpig's GitHub: https://github.com/goatpig/BitcoinArmory/releases

You should read the "sticky" posts stuck to the top of the board like this one: https://bitcointalk.org/index.php?topic=2227856.0

Unfortunately, for whatever reason, the original Bitcoin Armory people have left their website up and running... which seems to confuse the hell out of everyone... even more so than Armory itself and it's requirement to have a full Bitcoin Core node running behind it!
