You likely won't see it "come back"... it's a slightly misleading way to describe what change is. Your wallet will automatically detect that the 2nd output being created is being assigned to an address from your wallet, so it will recognise it as "change" and adjust your balances accordingly.

Bitcoin isn't like "internet banking" where you say send $68 to X... and it creates a transaction that sends exactly $68 to X... Generally, your wallet "balance" is actually made up of several "unspent transaction outputs" (UTXOs). These can be of all different values... and most likely, none will be the exact value that you're trying to send to someone.

So you wallet will group several together until it has enough to be greater than or equal to "the value you're trying to send + transaction fee". In your instance, you tried to send $68.33 and it used a UTXO that was worth, $69.02. It then broke that up into the $68.33 output... the $0.66 "change" output... and the rest ($0.03) was spent on fees.

You can read more about how "change" works here: https://en.bitcoin.it/wiki/Change


It isn't a service... you just create a new transaction that spends the unconfirmed output from the first transaction and use a large fee to cover both the original AND the new transaction so that a miner wants that large fee and has to include both your stuck transaction and the new high fee transaction to claim their prize

It would appear that you've attempted CPFP: https://www.blockchain.com/btc/tx/ee137508d705a0f8b45d25d92be306055da9ae535ef1b96c4235439b6b8a5913

Unfortunately, it hasn't really added toooo much in the way of a fee boost. I think the average fee you've paid across the 2 transactions is now about 10 sats/byte.

Total Size of txes: 226 bytes + 192 bytes = 415 bytes
Total fees paid: 0.00000226 + 0.00003840 = 0.00004066 BTC

Total fee rate: 4066 sats / 415 bytes = 9.8 sats/byte (which in new terminology is ~2.5 sats/WeightUnit because it's non SegWit)

While that is a bit better than 1 sat/byte, it's not "huge", but it is a lot nearer to the top of the pile, so hopefully your transaction will be confirmed in the next few hours.

If you want to do a CPFP, you'll probably need to

A. export your current blockchain.info wallet into electrum. Download electrum, get the seed from your blockchain.info wallet, check the BIP39 box, and you should be able to import your wallet.
B. Follow this guide, https://bitcoinelectrum.com/how-to-do-a-manual-child-pays-for-parent-transaction/

But this is only possible if you control the outputs that are being made here in this transaction. (Is that the case?)
(You could try CPFP the change address but i doubt that that 5000 sat is going to improve things.)





Or you could accelerate your tx:

Which is definitely not worth it.

That's true assuming that the OP only has that one UTXO left in their wallet... However, if they have other coins as well, then it wouldn't be that difficult.


It's right in the send dialog "Customize Fee":


Once you click that, you can set what you like:

Perfect time to test and see if any of the old accelerators still work! I just put your tx through Antpool's (free) accelerator, it must have been over a year since I last used but it still seems to work as before. Accepted the tx but no way of knowing if they really do line it up. We'll know if this confirms later and it's in an Antpool block I guess, not that that's confirmation it worked?

20 hour old transaction with pool at 30k unconfirmed... of which 23k are 1-2 sat/byte in fees.
