Hi! I have struck in unconfirmed bitcoin transaction more than 1 day and I don't know why if it's because low fees transaction or not. I'm in hurry of sending money. If anyone could help me,what should I do to speed up my transaction? Thanks in advance.

My transaction ID: 2e76b697c74a5d64d0ecf9eda210f60228c2d879c3214a5e6a0f8abf774863bc

Are you the sender or the receiver? What wallet do you use? Can you do CPFP?

I'm the sender. I use blockchain wallet. Can I do anything?

Not at the moment... with wallets like Electrum you can do a CPFP if you are the receiver or up the fees if you are the sender.

Your fee is very low.
From last few days the average fee is 30+ sat/B. Before that the average was under 3 sat/B
If you are not in hurry then leave it. It will confirm some day.

Bitcoin just went full skyrocket mode to $5000. This usually means that the mempool will get quite full (many people moving their coins to sell).

Right now (as I write this post), the mempool is catching up on 20 sat/byte transactions. You’ll have to wait until it cleans all the way to your fee range of 3 sat/byte.

If you are in a hurry to move your funds you should always check what the recommended fee is before you send the transaction.
https://bitcoinfees.earn.com/ usually shows a very high fee, at the moment it is 64 Sat/byte.
Comparing that with https://www.coinb.in/#fees they recommend 16 Sat/Byte.

64 Sat/byte is too high and you don't need to set it that high but doing double what https://www.coinb.in/#fees suggests (in this case 32 Sat/Byte) should get your transaction into the next couple of blocks. 

Are you sending this to a wallet you have control over or are you sending to a bitcoin address you have no control over?

You can also do CPFP without desktop wallet if you have the private key you can do CPFP using coinb.in.


Coinb.in has their own server or network that is why coinb.in suggesting or calculates recommended fee which is different to bitcoinfees.earn.com.

www.coinb.in/#fees can be use to calculate suggested fee but you must check first your unsigned transaction and how many inputs your transaction have you must slide the bar to specific amount of input.

Sample the transaction from the OP it has 7 input and 2 output look at the result below.

and compare it to bitcoinfees.earn.com

So, OP send a bitcoin which is too low fee not too high.

@tomika263 I recommend you to rebroadcast the transaction to different network/server you can use https://coinb.in/#broadcast
If you don't know how to get the raw or hex of your transaction you can follow this guide.

use this code below and replace this 9021b49d445c719106c95d561b9c3fac7bcb3650db67684a9226cd7fa1e1c1a0 with your hash ID and paste it to your URL bar.
and the result will show your hex/raw transaction copy all of them and paste it to https://coinb.in/#broadcast and submit.

Hoping that your transaction will be included to next block. So wait for 15minutes to 2hrs. This is just my estimation time.

You can replace your unconfirmed transaction with a new transaction and higher fee by using bitcoin-cli bumpfee "tx-id", but there are certain thing that you definitely must do before you call bumpfee. Make sure that transaction is replaceable, so you need to execute bitcoin-cli gettransaction "tx-id", and see "bip125-replaceable": "yes or no" (yes = replaceable)

If that transaction replaceable, you need to change the transaction fee by using bitcoin-cli settxfee <fee_per_Kb> (make sure the new fee is large enough), and then you can execute bumpfee command.

coinb.in doesn't actually have his own network, there's only one main network of bitcoin  
coinb.in has different fee suggestion because they have different method/algorithm on figuring out recommended fee

simply rebroadcasting exactly the same tx won't make much difference, still queued in any mempool
if he broadcasts a new tx with higher fee, there is a chance for faster confirmation
so his options basically are:
- wait until his tx is finally confirmed when network traffic clears up
- do CPFP, by making another tx using the change utxo (of prev tx) with high enough fee to cover both txs fee
- try double spend attempt with higher fee (similar to RBF), more difficult to do than the others two

He has literally one option: wait until its confirmed :)

Can't do option 2 if he's not the receiver and blockchain.com doesn't support Replace-by-Fee or even coin control (option 3):

OP please read this sticky thread by achow101: [READ] About blockchain.info's web wallet and "stuck" transactions (https://bitcointalk.org/index.php?topic=1914800.0)
It has all the info you need for this topic.

BTW, your tx fee isn't enough to be eligible for viabtc's transaction acceleration (free) service, try paid if you're really in a rush.

Thanks everyone for your help. My transaction is still unconfirmed but I will try some unconfirmed transaction accelerator and pay for them. I'm very new to bitcoin. Honesty I didn't know how to adjust fees when I sent bitcoin so I always use regular fees. And when I sent this transaction last 2 days, bitcoin is still around 4000$ and then go up so fast and network is very crowded. Can anyone give me an advice if any paid or free transaction accelerator is really working. I will try to use them. Many thanks for you help.  i'm very appreciated :)

Transaction accelerators do work but a paid accelerator is expensive, on btc.com's accelerator your transaction would cost $130 to get accelerated (https://pushtx.btc.com/unpaid/2e76b697c74a5d64d0ecf9eda210f60228c2d879c3214a5e6a0f8abf774863bc). If you want to save money just get your private key through blockchain -> security center -> backup passphrase and import it to a wallet(electrum) that would allow you to do RBF.

his transaction has 2 outputs, so I assume one is the change output back to his wallet
and option 3 can be done thru coinb.in or other means, that's why I said it would be 'more difficult' to do
