missing transactions

[dongolz]

Hello all,

A friend of mine sent two transactions to me, one on 21th july and the second 22th july

both were pending as he selected low fees,

Here are the links of both transactions

https://www.blockchain.com/btc/tx/59e6605571ee88d6e87a7fa75b18423337bff15f86444a69959d12e2a0e09c89
https://www.blockchain.com/btc/tx/2c8082ae3a9e9e498c8d2b8e13173b82cb35f738fd81611e56bb14056285579e

a friend mine suggested that he sends 1$ to each address again with custom fees 4$ to make the earlier/previously mentioned/stuck transaction go into a pool

so my friend who send the transactions did so and the latest transactions got confirmed already
the point is now, the first two transactions gone missing and the recent two got confirmed

here are the links of the recent transaction
https://www.blockchain.com/btc/tx/1c4a23fdf7bdd696ea25ccd9250b97d39f3cde5e186cc036939ef8cebda14736

if you try to open the links of the first transactions, it says "not found"

i received the money on my wallet but whenever i try to send it says insufficient funds

I really dunno what to do, thanks in advance

The transactions most likely were dropped from the mempool due to the fees being too low. (When this happens block explorers also remove the data, reason why the txid is not assessible. Sending small amounts of bitcoins to the same address does not hasten the initial transaction except you're spending the exact output from that transaction. Ask the sender to confirm if the bitcoins has been returned to their address.

Some wallets allow one to bump the fee after broadcasting. You can also use RBF, where you send the exact same output but with a higher fee.

thanks for your answer

the question is, i have the money on my wallet (the sender said he hasn't gotten it nor can he see the transactions on his wallet), will it become useable? What will happen to the money of both transactions as i have it on my wallet but can't use it?

How can i use RBF for future?

You could specify the wallet you're using so other users can help you better. The default expiry date for a transaction is 2 weeks, so it's unlikely it was dropped except a node manually did that.

RBF is not advisable to use, it's better to check for the suitable fee at the time of sending so as to prevent it getting stuck, here are some tools to check that;

Fee estimators

• https://btc.com/stats/unconfirmed-tx
• https://estimatefee.com (recommends a fee estimate after you set a number of blocks to confirm within (Update April 6, 2019: the recommendation from this site is 3 times higher than what my Bitcoin Core recommends) -- thanks lite)
• https://jochen-hoenicke.de/queue/#0,1w (thanks pooya87)
• https://coinb.in/#fees (The recommended fee seems "stuck" at a high value, don't rely on this site! But it also lets you manually select inputs and outputs to see the transaction size (in bytes), so I don't remove it from this list yet)

The sender and I use BLOCKCHAIN
I just want to know what will happen to the BTC/funds, will it go to him or will I be able to use it in the future. Thanks for your patience

If not confirmed after the timeframe, the transaction would be dropped and the funds would return to the sending address. If the transaction is eventually confirmed your wallet would be credited. Bitcoins cannot be lost, the transaction could be dropped by the block explorer invalidating the txid, while it's still in the mempool afaik.

Please answer a few questions so we can find out what happened.

Does the BTC show up in your Blockchain wallet?
If you check your transaction history, do you see any of those two missing transactions there?
If not, do you see anything at all that justifies your balance increasing (any other transaction with same value)?
How much did he sent you (in the first 2 transactions)?
What is your Bitcoin address?

I highly doubt that a transaction would be dropped from the mempool after just 1 and 2 days.

If you check your transaction history, do you see any of those two missing transactions there? noo

If not, do you see anything at all that justifies your balance increasing (any other transaction with same value)?  noooo nothing justifies the amount

How much did he sent you (in the first 2 transactions)?  385$ the first and the second 320$

What is your Bitcoin address?   19G7DFWfbXwPx9fexsLuUqvXWLCH3M9ka8  &  1412gFZMtB1Cz7pfRyCm2r3M2u1bA1ETnA

 these are the addresses which were used in both transactions

I just searched for your transaction in a few other block explorers and the two transactions actually show up on BTC.com and Blockchair.com

https://btc.com/2c8082ae3a9e9e498c8d2b8e13173b82cb35f738fd81611e56bb14056285579e

Because of that, I managed to get the HEX of the transaction and push it back to the mempool through Blockchain.com's website. It should show up just fine now.

What did we learn today? That Blockchain.com sucks. Consider something more secure like Electrum (electrum.org), which is one of the most used non-custodian desktop wallets. Do some research to not fall for scams and phishing websites, though.

Thanks so much for your help your assistance is highly appreciated bro! so is it more likely now to get confirmed?

Well, it's still going to take some time since the mempool is congestioned and fees are a bit high.

What your other friend suggested with the $1 transactions was a good idea, but the sender just didn't execute it well. You can accelerate the transaction by asking the sender to make 2 new transactions with a higher fee, but just not any transaction.

The coins should be coming from the addresses that received the change from the transaction.

For example, the second transaction: https://www.blockchain.com/btc/tx/2c8082ae3a9e9e498c8d2b8e13173b82cb35f738fd81611e56bb14056285579e

Sender
1GvZTm27pHyH9RECRidzhpFiaquhgubw4f 0.04090700 BTC < sender (address where are the coins)

Receiver
1BJdY1fzV2V6WdU3q4rabFwVwU94ePZkMC 0.00040253 BTC < another sender address, receiving the change
19G7DFWfbXwPx9fexsLuUqvXWLCH3M9ka8 0.04048187 BTC < your address

The 1GvZT... address (your sender's address) is sending 0.04048187 to your address (19G7D....) but there is also 1BJdY1... that is receiving 0.00040253 BTC (the change of the transaction). This address is also owned by the sender, so he must spend those 0.00040253 BTC so the miners must confirm your transaction before confirming the new one (the new one depends on the old one).

Unfortunately, I don't think Blockchain.com supports coin control (spending only the 0.00040253 BTC originated from that transaction), so his only shot is probably to send all his balance to himself with a higher fee (that is, if Blockchain.com allows him to spend unconfirmed coins, which I'm not sure if it does). I hope that's not too confusing.

When the first two transactions got stuck, my friend suggested that he sends 1$ to each address of the stuck transactions with high fees to push the stuck transactions, but sadly this did not happen
the new transactions (1$) got confirmed and the old ones disappeared!
I just want to make them confirmed because i do not guarantee that my friend will send them again if the money rolls back...
I see on https://btc.com/ that there's an option called transaction accelerator, does it work 100%? it is kinda expensive

It does. You usually can't trust any "transaction accelerator" since 99% of them are a scam and fake. But BTC.com has its only mining pool, so you can pay them so they include your transactions in the next block they mine (or maybe now they have some deal with other mining pools...? I don't know).

It is indeed expensive, so it's your call. Either wait or pay them for a quick confirmation.

Since you confirmed it is not a scam! i will wait till tomorrow, if nothing changes, i'm going to use it! again thanks so much for your help and clarifications

There is also ViaBTC's and Antpool's free accelerators, but they are usually full. You need to keep trying from time to time until you get your transaction in. Good luck!
