I have two unconfirmed transactions.

adceef304e538aff19fef8ce4713043ccda70c296113317753a1835f906f693b
5c5bbea169de68dfa3413c961e098867341604153d2bb605d535ef096148e634

The first transaction was an experiment to see how long it would take to get bitcoins sent with the lowest fee. The second is one is money i care about and "need".
I've spent some time trying to find a solution to the problem, and an explaination to why it happened. Obviously things didn't work out, so now I'm here. I contacted viaBTC after their accelerator told me my transaction "does not exist", and they told me it was a double spending. The transactions were sent from "Bitcoin Core v0.14.1", one 20 hours before the other.
I have also tried to contact "macbook-air" and "Quickseller" with no luck so far.

Is the second transaction stuck because of the first one, or does both simply have a too low of a fee for anyone to care about confirming it? Should I wait and pray or do something with it?

Thanks in advance for any help.

I cannot see the second transaction but your first transaction can be seen here: https://www.blocktrail.com/BTC/tx/adceef304e538aff19fef8ce4713043ccda70c296113317753a1835f906f693b which has a fee of 0.00001000. Since it was rejected by blockchain, you can resend the amount adding the appropriate fee of atleast 0.0002 BTC (which will give it a higher priority to get confirmed). It seems the second transaction again had a low fee due to which it was removed from the network and viabtc doesn't accept transactions that are double-spends. Since your first transaction itself had a low fee and was rejected (still present in the network though), viabtc won't recognize it.

I have two unconfirmed transactions.

adceef304e538aff19fef8ce4713043ccda70c296113317753a1835f906f693b
5c5bbea169de68dfa3413c961e098867341604153d2bb605d535ef096148e634

The first transaction was an experiment to see how long it would take to get bitcoins sent with the lowest fee. The second is one is money i care about and "need".

I checked both your transactions in blockchain.info, and the second transaction spends unconfirmed coins sent from the first transaction with the very low fee. The second transaction can't confirm until the first does.



https://blockchain.info/tx/5c5bbea169de68dfa3413c961e098867341604153d2bb605d535ef096148e634



A few minutes after I checked your low fee transaction I tried again, but blockchain.info's node had already forgotten about it.



The node connected to the blockcypher explorer still shows your transaction.

https://live.blockcypher.com/btc/tx/adceef304e538aff19fef8ce4713043ccda70c296113317753a1835f906f693b/

I got the raw format of it from blockcypher and tried pushing it through blockchain.info's transaction pushing tool. However it rejected it with an error message that it was transaction version 2.



This is your low fee transaction in raw format. If blockcypher forgets it you could try submitting it to blockcyoher's raw transaction pushing tool here https://live.blockcypher.com/bcy/pushtx/

0200000001f5887538f6224ec42f0b6ba7540a7c0b9c2e2b3f4b8e8599216b2ede8ec33bb500000 0006b4830450221009064746ba62e1b34303eb607b9b01f1e15ce085e041540a3fe8583b985113a 36022006ea6a4dfd6ec2ecd717284c8491430f7aae4ec1f81828c4c30d822e9b54d41c012102461 6d088edb7c1cd7d6386a162db1aaee2fe82866a07a7af3d915580fdfc136efeffffff0240420f00 000000001976a9148a06b479098a015154eff843db30db5edd15d5ed88aca737280000000000197 6a9145c42b1012c33c1dfb230ecaa018a805e2c391ded88ac4b1a0700

I tried pushing your raw transaction through blockchain.info, but it rejected it with an error message that it was transaction version 2.

edit

I tried pushing your transaction through blockr.io, but that tool also rejected it.

If I do so will the first transaction appear in the address I sent it to with the new one?

Yeah, its seems that blockchain ?dropped? the transaction for lack of a better word literally seconds after I posted this thread.

What now? Is there any way I can get the bitcoins back?

Eventually all the nodes in the Bitcoin network will forget about your transaction if you do nothing. Afterwards your coins should return to your wallet and be spendable again. However some wallets keep resending unconfirmed transactions, so it might be best to close your wallet and check your address through a block explorer.

Blockcypher is usually one of the last explorers to remember a transaction.

https://live.blockcypher.com/

A moderator here posted a guide explaining your options for dealing with a stuck transaction. One of your options is to do nothing and wait until you get your bitcoins back.

If the transaction is forgotten and I keep my wallet shut for the time being to stop it from resending the transaction wouldn't it resend once I open the wallet back up?

What do you think about what "erikalui" said. Could I resend the amount with a higher fee to push both transactions? Would that affect the second transaction of 122 sat/B?

I can ignore it for a week or two if that guarentees that the bitcoins will be back. But if the other option is "safer" I would rather go with that.

Sorry for the overwhelming amount of questions.

I'm not an expert at using Bitcoin core, and this link from 2013 might contain out of date information.

https://bitcointalk.org/index.php?topic=232979.0

However, it says core will rebroadcast unconfirmed transactions every 30 minutes while the sender keeps his wallet open. If you read the whole thread it explains how to deal with unconfirmed transactions, but as it's from 2013 it might be out of date. I'm sure other users here can advise you better than me about core.


How do I resend a transaction?
Bitcoin-qt will rebroadcast unconfirmed transactions every 30 minutes or so. As long as the sender has his client open, the transaction will be rebroadcast.


How do I resend a transaction with extra fee?
For Bitcoin Core users:
  • Right click the transaction and choose "Abandon Transaction"
  • Send the coins again with a fee
Third party client users


How do I remove an unconfirmed transaction?
If you do not want to see the unconfirmed transaction, you can remove the transaction from your wallet. Once the transaction gets confirmed, it will reappear in your wallet.

If the transaction is forgotten and I keep my wallet shut for the time being to stop it from resending the transaction wouldn't it resend once I open the wallet back up?

If your computer is connected to the internet (to peer bitcoin nodes)?

Yes.

If you can turn off or block your internet connection, then you can open up your wallet and use the "abandon transaction" to get Bitcoin Core to forget about it (in which case the bitcoins will instantly re-appear in your wallet.

If abandon transaction doesn't work, then you can start up your wallet from a command line with the -zapwallettxes command line option to get your wallet to forget about the transaction.

Once the wallet has forgotten about the original transaction, then you can re-enable your internet connection and will have access to create and broadcast a new transaction using those bitcoins if you want to.

After said instructions do I have to re-spent the same amount of BTC to the same address?

Thank you for the help, Danny. It worked out <3
