Achow helped me CPFP it

He checked your unsigned TX and didn't see any problem, so he suggested I download Bitcoin Core and he gave me script to sign the TX again, and it worked!

It got into a block during the night , seems like you were lucky, or did you manage to contact quickseller or macbook-air, or did you do something else?

Altcoinhosting did everything he could, I want to thank him alot!

Unfortunetly there was some error in script or something, and I couldn't broadcast that transaction..


Anyone else want's to try help me ?

Can you try what i've PM'ed you and give some feedback... I'm running out of idears here. I must have missed something here

I really have NO clue what is going on, only thing I know that pushing that TX gives error:

Script resulted in a non-true stack: []

Can't seem to find the problem i'm afraid...

I generated a raw transaction using bitcoin-cli createrawtransaction '[{"txid":"410c33782752a5539005722d6ebc17428c8d68f116fda359635acea7a83943db","vout":0}]' '{"1NbjE76xjJYpFRNFr9xceVudhW4PXdYH7x":0.121}'

Giving me an unsigned raw tx hex of

which you signed... But i can't seem to find an error here... I must be overlooking something.

Sending to you via PM

It's been a while since i last executed these steps... Usually, i create the transactions from the core wallet that holds the private key for the address, and i also use core to sign and broadcast the tx. But since syncing core will take several hours/days, it's not really an option here.
Would you mind posting the signed transaction? It shouldn't contain sensitive information, since you would broadcast it to the network anyways.

Tried to broadcast it, got  16: mandatory-script-verify-flag-failed (Script evaluated without error but finished with a false/empty top stack element)

There are several ways to proceed. I find the simplest this way:
1) surf to https://coinb.in/ download the sourcecode to your pc, open the index
2) go to the sign tab
3) enter your private key and the unsigned tx and sign the transaction
4) doublecheck everything (same link as my previous post)
5) broadcast the signed tx (copy the hex code, paste it https://blockchain.info/pushtx and click broadcast)

preferably, execute step 2-3 offline.

PS: do realise this is only a longshot... Your best shot still lays with quickseller or macbook-air. They can still add this transaction to any block their pool mines, even if it didn't have a fee at all.

But if i'm correct, if you follow these 5 steps, you would have made a successfull CPFP, since the child transaction (the one you're signing is paying enough fees to cover both himself and the unconfirmed parent transaction... The parent being the probable scammers transaction)

I am fine, lets go mate!

I asked you to import the pk into electrum because it's an easy way to verify the private key... But since you have the private key, i can try to PM you the next step

EDIT:
I create a raw, unsinged transaction for you:

0100000001db4339a8a7ce5a6359a3fd16f1688d8c4217bc6e2d72059053a5522778330c4100000 00000ffffffff01a0a1b800000000001976a914ecec08591e99b247d1645252b224ec46472d5e7c 88ac00000000

DOUBLECHECK this transaction, even better, ask some other trusted members to doublecked if you're not 100% sure... I'm not responsible for any errors in the tx!!!

In theory, when you sign this transaction using your private key and broadcast it to the network, it should be a CPFP transaction...
It uses the unconfirmed output from the hanging transaction as an input for a new transaction. The output of the new transaction goes to your own address, and the fee is a little over 0.0007BTC.
Why? The hanging transaction is 223 bytes, the new transaction should be roughly the same size, so i took a total size of 500 bytes * 120 satoshi's per byte =60.000 satoshi's. I rounded up to 70.000 satoshi's (= 0.00070000BTC)

Do realise the new fee will be payed by you... It is taken from the second transaction (from your address to your address).
If you doublechecked the transaction, and you're fine with it, i'll try to help you to sign it and broadcast it.

EDIT: the hex gets messed up due to the forum sometimes, here's a code block with exactly the same tx as above:

Alright, I got my Electrum ready and exported my key there.

Now waiting instructions to perform CPFP

No problem man, like i said, i really hate scammers myself...
In the meantime, i found the correct username of macbook-air... You can pm "macbook-air", "Quickseller" . They both have acces to a bigger pool and could potentially include any transaction they want into a block.

Like we discussed, the other options are: creating CPFP using the unconfirmed output, in case you succeed in exporting your private key or keeping rebroadcasting the transaction so at least it isn't forgotten

It is same guy, but this 80$ transaction was made 24 hours ago.

This smaller one was like 2 hours ago.

I am trying those tricks that altcoinhosting (thank you so much for trying to help) is telling me.

If it's the same buyer you have to act quickly.
This transaction also has 1000 satoshi tx fee, which imho it means 8h or more to confirm unless doublespent.

Yeah I understood that first one is lost and gone, but hopefully that second transaction can make to my wallet safely!

Wait, one step back please... The advice i gave you both in this post and in PM was under the following assumptions:

1) you got payed in transaction
https://blockchain.info/tx-index/184988716

2) you got a second payment: https://blockchain.info/tx-index/410c33782752a5539005722d6ebc17428c8d68f116fda359635acea7a83943db from the same user which is still unconfirmed

The first transaction was using inputs that were doublespent and is lost, no way of "recuing" your funds... The second one is still unconfirmed and can still be salvaged... The advice i gave you was for salvaging the second (unconfirmed) transaction!

What could be possible reason for him to let it not go through in couple days?

I mean, is it still possible to him to double spend that, or what is his scam in this bigger transaction?

From what I see the other transaction from the double spend is already confirmed.

Yours: https://blockchain.info/tx-index/184988716
Confirmed: https://blockchain.info/tx-index/184989041

The buyer had 1000 satoshi fee for the first transaction (so he didn't really want it to go through these days) and 14000 satoshi for the transaction that went through.

no problem, i hate scammers
these tips are only a longshot tough, but it's defenately worth a shot... I'll edit this post in a few minutes if i successfully find macbook air's profile

BTW: as long as the potential scammer doesn't double spend the inputs to create a new transaction AND gets this new transaction in a blog, you could potentially keep broadcasting the transaction, so it isn't dropped from the mempool:

Thanks for tip mate! Didn't find that macbook guy, but found quickseller and gonna PM him!

Maybe you could contact macbook air or quickseller and ask if they could potentially add this transaction to one of their pool's next mined blocks?
If you offer them a bounty in case they can add the transaction, the transaction might not be lost completely... Or you could try CPFP and spent the unconfirmed output of this transaction. Just create a second transaction using this unconfirmed output as input and your own address as output, but add enough fees for both the stuck transaction and the new transaction... Might work, might fail...

And the day gets even better.

Thanks for info mate!

It won't confirm, it will eventually be dropped or it can be double spent at any time.

Not legit.

Nice!

Such a great day


This is from same guy:

https://blockchain.info/tx-index/410c33782752a5539005722d6ebc17428c8d68f116fda359635acea7a83943db


This shows in transaction, so I assume this is legit?

It's gone!

You can see here where it went:

https://btc.com/1ApMAypm43JqVovS3Uy8pWpAPTXUjaCrYC

Was doing my trading as usual, sold some virtual stuff to one guy.

Well, trusted him cause confirmations have been so slow.

https://blockchain.info/tx-index/184988716

Now it says double spend and I can't see whole transaction in blockchain?


First time this kind of stuff happens, so give me mercy. Might be crystal clear thing to someone, but not to me.
