Bitcoin Forum

Hey.

I am in a bit of a mess right now as i have two unconfirmed transactions stuck in the network, the first one was due to very low fee as i did not notice i had on very low fee and i then tried to doublespend the coins and now i see that even the next one is unconfirmed for several hours.

It's possible to see one of the transactions on blockexplorer and all others but the new transaction is only visible on Blockchain.info as i can see.

What can i do guys, i'm really in need of these coins asap. Using bitcoin core btw.

Best regards

Post the transaction IDs so we can understand what's happening better.

Txid for the new one: f96ee3d9009945026b951382511247f928e59f48206f07986ef966108e058ae1
And the old one: 06fba0277a866beeb71c8d95a0bf6721bc9b3c1d220a0c4cd7b9d55a3b576b53

Thought that double spending would rid me of this problem but now I seem to be in a bigger mess actually.

Both have low fee actually.  The first (old) one is using less than 1.5 satoshi per byte which makes most nodes reject it and the second transaction is using only 35 satoshi per byte.  The reccomended fee is 76 satoshi per byte according to https://btc.com/stats/unconfirmed-tx.

You can try using this site (https://www.viabtc.com/tools/txaccelerator/) to make the second transaction confirm faster.  It might still take few hours though.

ViaBtc rejects all transactions that have a fee of less than 10 sat/B. And since his second transaction spends an unconfirmed output from his first transaction he cannot push it to ViaBtc because that transaction simply doesn't exist in their mempool.

Uhh.  As far as I can tell the second transaction (new) is a double spend of the first (old) transaction.  Both are not spending any unconfirmed output.

So what is the best solution for me right now? Could i make a third try and spend the coins with a very high fee and get it through? Made the second transaction with the recommended fee on bitcoin core.

My bad. I though it was the usual case. The guy sends a tx with low fee then spends the change and complains that his "high fee" transaction doesn't confirm. So I didn't even checked the explorers.
Spend one of those outputs from your new transaction with a high fee of 200 sat/B so that both transactions get included in the block. There are a lots of CPFP pools nowadays.

Do I need to spend from the wallet i recently sent to, or am I to spend from the original wallet that has two unconfirmed transactions sent?

Let me explain a little better: From my bitcoin core wallet, I made both transactions to two different wallets(thought that was what double spending ment). Now i can still -zapwallettxes and try send the bitcoins for a third time to another wallet, is that what you mean or do i need to spend from the new wallet that was supposed to recieve the bitcoins?
The new wallet have not recieved bitcoins yet, and therefore can not spend any bitcoins or am I wrong?

Spend the coins from your new wallet. Do NOT double-spend them again.
What do you mean they did not appear? Do you ask if you can spend unconfirmed outputs. Then the answer is yes.
If your coins however did not appear please sing one of these transactions (only one is required)
With private key of 1MJF22LL41V1BNdvzucU4z41T5pEoZ5Xio
OR
With a private key of 14SqwLchTWUwjK35Vs8cWU9jzZQa1KLMou

They both send coins to the same wallet with a fee of 0.001BTC.

I sent my first transaction to a company for buying items, so i am not in control of that wallet that was supposed to recieve the bitcoins

The second transaction was sent to a localbitcoins wallet that has not yet recieved the bitcoins so i am not able to send any from that wallet.

First output or first transaction. If it's first transaction than forget about it, that transaction will never confirm.
Again second output or second transaction? Do you own any of these addresses?

14SqwLchTWUwjK35Vs8cWU9jzZQa1KLMou
If yes, do what I told earlier, if no double-spend that transaction and now send it with a truly high fee. At least 0.0005BTC

Dude i am very new at these things  :-[

How can i sign as you said?

Haven't used bitcoin core wallet for years. But it should be something like this:
In console tab (if that thing even exists in newer wallets) type signrawtransaction rawtx.
Replace "rawtx" with one of those that I gave you.
I do not guarantee it will work. As I said I don't use any standalone wallets.

Well i could try that, but what happens if for example: I have 20 bitcoins, and sent 10 bitcoins to one Adress wich is unconfirmed, Then i -rescan and -zapwallettxes and now i still have 20 bitcoins, now i decide to send 15 bitcoins to another adress with very high fee.

Is it possible for that transaction to get validated even though i alredy spent 10 bitcoins though the transaction is still unconfirmed?

By the way, has the remaining 10 bitcoins alredy changed adress or will the change of adress occur when the first transaction is confirmed?

As long ass the first transaction is unconfirmed, yes.

This would all be possible, but it's also tricky with change addresses and backups. Considering you have to ask the question here, I recommend not to do it. Do this:
This will work.

Next time, for a $8000 payment, use more than $0.08 fee :)

Well i just made a double spend and payed a 101 satoshi per byte fee, now i do regret and wish i would pay more fee but im still not totally understanding how much fee i should pay.

And somebody mentioned before that Viabtc will not help with double spending.

It will not. Please read the the whole thread before spamming your signature.
Still too small. But the weekend is almost here so mempool should clear up. Also I said what fee you should use (0.0005BTC).
You can also check them here bitcoinfees.21.co (http://bitcoinfees.21.co)

Edit: I read more posts of LoyceV and it doesn't seem like he's a signature spammer. Still though next time read a little bit more of the thread not just first and last reply.

Yakuza do you think i lost my coins forever now?

Hehe. No. Don't worry, tomorrow the mempool will be close to empty and then is when your transaction will get confirmed.
I do not guarantee it, but the size of the mempool is usually a lot smaller on weekends.
Also you sure you don't have private keys associated with these addresses 1MJF22LL41V1BNdvzucU4z41T5pEoZ5Xio ; 14SqwLchTWUwjK35Vs8cWU9jzZQa1KLMou
Because if you do you could CPFP and your transactions would be confirmed in less than an hour.

Wait, just wait. Dont worry your coins in safe. One time Im wait 3 days until my transaction confirmed. Next time you need pay more fee

My coins are now safe, but i see that the old unconfirmed transactions are still in the network, will they automatically be dropped and erased from the network or do i need to do something?

They are already dropped from the "network" though they will still stay in your wallet. You should zapwallets. And then everything should be ok.

yakuza is wrong. 101 satoshis per byte isn't too small, just below the recommended. Your transaction should still be confirmed within the hour. I sent this tx[1] with ~80 satoshis/byte an hour or 2 ago, and it confirmed within 5 blocks. ViaBTC should still be able to confirm your transaction if you submit it there.

My transaction is alredy confirmed and done with

Now i wonder, since i did zapwallett and then made the last transaction I can no longer see the previous unconfirmed transactions.

Do I still need to zapwallet or should I not worry anymore?

You don't need to worry anymore. If your replacement transaction as confirmed, then the previous ones that it replaces are now invalid.

I did read the thread, and I think you were wrong here:
Double spending doesn't mean spending an unconfirmed output, it replaces that transaction and uses the original confirmed output to start over. Since that one had a high enough fee, ViaBTC could pick it up. Unless ViaBTC rejects transactions that are double spends, but I see no reason why any miner would do that. And yes, I checked the txid.
If I'm wrong here - which I doubt - I'd like to know where I'm wrong. I now want to test it by myself.


^{BTW, if you think I'm sig spamming: my campaign manager has a small reward for you if you report me. No need to mention that in any threads.}

So I had a guy sending me private messages trying to explain to me that i have a debt now because of the unconfirmed transactions and even went as far as telling me to go to my bitcoin core client as he wanted to help me Sign message etc, telling me to dump private key and all, that was a fraud right?

Obviously :)
Please name & shame!

On Bitcointalk: miningdude
He said he told a friend of him to help me out. A friend very experienced with bitcoin etc... But i am very sure it was him all along.

He gave me skype ID so he started talking with me through skype, saying he would like a 0.001 tip for the help when i was done helping me, i sent him 0.002 btc instead while he had not helped me with anything at all, and still he was going on about how i must do the signature etc.

if someone asked you for private key it means he/she trying to access your address please read about https://blockchain.info/wallet/bitcoin-faq

And that's exactly what I meant. Though if the fees are below recommended and mempool's size does not decrease the transaction wouldn't have been confirmed.
That statement is correct though it wasn't the case since his second transaction did not spend outputs from first transaction. It double-spent first transaction.
You are 100% correct on this one. Probably ViaBtc has some checks to see if it's double-spend or not. Though it's strange that they monitor even transactions with a fee of 1sat/B.
I apologize you are not spamming. It's just that his second transaction couldn't have been accepted by ViaBtc.

I trusted Yakuza with all he said, because i wrote private messages without having him replying, he was honest enough to reply in the thread even though i offered to pay for help as i was desperate.

I had you "miningdude" coming directly to private message sending me to "some shady dude" who would help me solve the problem as "he" seemed only interested in private keys.

Thanks everyone for the help even though it seemed so complicated, in the end it worked out fine, i'm now even more interested in Bitcoin.

I might be very new here, but after reading your previous posts, miningdude, i can clearly see you are just a fraud lurking around on this forum.

You need to try this feature and enter your transaction id tx if you want to try it
