This is your transaction. It paid a low fee of 55.423 sat/B.

This is the confirmed double spend transaction. It paid a higher fee of 200.889 sat/B

https://blockchain.info/tx/b1bc2a8b6efb86b16b86c5c9cd284aeb227c5c5e76ef8b6617836400c6dd3658

This address 17jjXhAt6yT2Lsr7mm1YRbw1xiv7zqm222 spent the same 0.041254 Bitcoins twice in two different transactions, one with a low fee, and the other with a higher fee. In that situation the miners are likely to confirm the transaction with the higher fee and ignore the other because they get paid the fees.

Most wallets won't let you spend the same coins twice, but a few of them will.

You can find it in my profile page here. The viabtc pool mines blocks at random times. Sometimes its blocks are a few hours apart, and sometimes they are twelve hours apart. It mined its last block less than an hour ago, so hopefully it will mine its next and confirm your transaction in a few hours.

Accelerated

I managed to submit it to the free viabtc accelerator, so you don't have to pay a miner, or to use the paid one. Unfortunately you will have to wait until the viabtc pool mines its next block before it confirms your transaction. There's a list of its last blocks here.

If you are very desparate for confirmation you could pay quickseller or macbook-air to get f2pool to confirm your transaction. Click their names in the quote below to open a page where you can pm them. If you do that then your transaction might get confirmed faster if f2pool mines a block before viabtc.

It's too late, your coins were spent in a double spend transaction that now has 68 confirmations.

https://www.blocktrail.com/BTC/tx/b1bc2a8b6efb86b16b86c5c9cd284aeb227c5c5e76ef8b6617836400c6dd3658

Some block explorers have already forgotten your transaction and only show the confirmed double spend transaction. Eventually they will all forget yours. I made this snapshot of your transaction so you can prove it was made after all the block explorers have forgotten about it.

Your transaction has inputs from this unconfirmed parent transaction.

https://blockchain.info/tx/9b153bf6fc044afc033f4d55a48b1032cad7d7a11df9f8a25a2a150747fc60df

Your transaction can't confirm until that parent transaction confirms. Your transaction pays a 121.071 sat/B fee, and its unconfirmed parent pays a 132.389 sat/B fee. That's high enough to use the free accelerator. If you use it then you need to put the unconfirmed parent into it first, before you put your transaction into it.

I couldn't find any unconfirmed parent transactions stopping yours confirming, and it has no double spends I could find. I think the reason it's taking so long is it only pays a 122.85 sat/B fee, and the networks's overloaded with almost a quarter of a million unconfirmed transactions.

For fast confirmation today you need to pay a 420 satoshis/byte fee according to https://bitcoinfees.21.co/

The free viabtc is very popular at present, and it's difficult to get included in the first 100 transactions an hour that it accelerates for free.

However, viabtc now also provides a paid accelerator service. If you want to pay to use it you have to email support@viabtc.com, and it costs 0.01BTC per transaction. The bottom of the free accelerator page shows this quoted text.

Coinb.in spits out that same error message when you try to broadcast a raw transaction with an extremely low fee. The screenshot below was from when I tried broadcasting someone's transaction that only paid 1 sat/B. Maybe coinb.in uses an electrum server in its backend.

https://coinb.in/#broadcast

Surprisingly it confirmed about twelve hours ago, and it only paid a 44.248 sat/B fee. Did it confirm by itself, or did you use an accelerator service, or a miner to confirm it?

https://blockchain.info/tx/f6b0e691e5ca212e9ac42b03971fbe3da0c3a2e44eb295e157032941da2f0327

If you are stuck the ViaBTC accelerator works. ViaBTC confirmed Joel_Jantsen's stuck transaction in block number 466914 when it mined it.

https://blockchain.info/tx/b191e996b02819c69dae9beff09c1afb81568d2141dd9561e991962593795953

Did your transaction have a lot of inputs? If it's got a lot of inputs you have to pay a higher fee. If you make sure it's only got one input, then paying a $2 fee should get it confirmed in the next block.

Yes, try contacting quickseller and macbook-air and offering either of them a small fee to confirm your transaction. Click their names in the quote below to open a page where you can pm them. They must be snowed under with similar requests, but it's worth trying.

Why do you want to cancel your transaction? Did you accidentally send it somewhere you didn't want it to go, or is it just taking too long to confirm?

One of the inputs to your transaction is unconfirmed. Your transaction can't confirm until this transaction confirms.

https://blockchain.info/tx/1b7dbaf6b2f97d53730a2224e65afddf4a21a30322bb7f95142aa32ac34ff22f

Submit the transaction above to the viabtc accelerator first, and after its accepted it then submit your transaction to it. The viabtc accelerator won't accept transactions with unconfirmed inputs like yours.

I successfully submitted your transaction to the viabtc accelerator service. Now the viabtc pool will confirm your transaction in the next block it mines if it hasn't confirmed before then. You can find a list of its most recent blocks at this link. It usually mines at least a few a day.

I posted instructions for extracting the private keys from Bitcoin Wallet for Android at these two links. However, it's a highly technical process.

Your transaction is final, its opted out of replace by fee so you can't use that technique.

You could try the free viabtc mining pool's transaction acceleration service at this link, but it only accepts 100 transactions an hour and it's overloaded with requests.

https://www.viabtc.com/tools/txaccelerator/

Viabtc now also provides a paid acceleration service. It costs 0.01BTC to use its paid service, and you have to email support@viabtc.com to use it.

You could try could paying viabtc 0.01BTC to confirm your transaction.

There is a link at the bottom of the free accelerator webpage.


After you click it this text explaining how it works is revealed.



As achow101 says you could try contacting quickseller and macbook-air and offering them a small fee to confirm your transaction. Click their names in the quote below to open a page where you can pm them.

I tested using a multibit HD version 0.5.1 seed in mycelium and it didn't work. I hadn't checked mycelium's derivation path or the available options for restoring from seed until now.

This information from github must either be out of date, inaccurate, or I did something wrong.

https://github.com/keepkey/multibit-hd/issues/687


This is the seed I used.




It generated this additional datestamp 3056/49

These are the first 3 addresses it generated.








When testing the seed phrase in mycelium it asked "do you want to restore a backup or create a new wallet". I selected "restore backup" with a 12 words length word list. This is the first address it generated.


Mycelium lets you add an optional password to your seed phrase, so I tried restoring a new wallet by checking both the 12 words option and the "I have a passphrase" option, and using the 3056/49 datestamp as password. It generated this address.


Finally I tried using my multibit password "a" as a mycelium password, and it generated this address.

I'm not sure what's the best thing to do. I tried the first transaction in the viabtc accelerator, but it said "acceleration failed" which is a message I don't think I have seen before. I have seen "submissions are beyond limit.", and "transaction doesn't exist", but not "acceleration failed".

I suppose it depends how urgently you want the situation resolved. If it's urgent and how are prepared to pay you could contact support@viabtc.com and arrange to pay 0.01BTC to get each transaction confirmed using its paid service.

A multibit seed phrase won't work properly in electrum, the same phrase generates different addresses in electrum compared to multibit.

The easiest solution is to install breadwallet on your phone and use your multibit seed in it. However you either need an iPhone, or a recent android phone. Breadwallet won't work on older androids.

If you choose to install breadwallet make sure you install the real one, there are fakes constantly appearing in app stores that will steal your Bitcoins.


A mycelium wallet running on an older android might also be able to import multibit wallet words. The quote below explains what to do, but I'm not sure if it works because I don't know of anyone who's tested it yet. Apparently you have to use the "Rescan Account" option after importing your wallet words.

edit: I tested using a myltibit HD seed in mycelium and it didn't work.

If you test it and it works please post the results here to help others in the same boat.




There's another more technical solution at the thread link below. If you try it make sure you install virtual box or vmware and run the offline webpage described in it inside a virtual machine. If you use a virtual machine any malicious code in it can't steal your coins. I don't think there is anything malicious about it but it's best to be safe than sorry.

Check your receiving address on blockchain.info.

https://blockchain.info/

If it shows your address contains the coins from coinbase then try restarting your electrum wallet.

If that doesn't work then try the instructions below. Sometimes a server electrum's connected to gets out of sync with the Bitcoin network. Selecting a different one fixes the problem.

Click tools, then network. A popup box should open. Uncheck "select server automatically" and keep selecting new servers from the list that appears, then clicking the OK button until your balance shows up.
