Bitcoin Forum

Hi all I am relatively new to bitcoin and sent 0.1 bitcoins without paying a fee. I just assumed that the fee is added automatically. Anyway it's been 15 hours and  is still unspent with zero confirmations.

Will this ever be confirmed or returned to my wallet. Or lost forever?
Thanks

It'll either eventually confirm or be returned so just have patience.

I think BTC transfer without any fee will finish after a few days  ;)

Can you even send a tx without a fee? I thought you need a minimal fee to send bitcoins on the network?

yes you can do that though the confirmation of the transaction can take up to a few days i think its better to include the fee as then the transaction gets confirmed as soon as the next block appears on the blockchain

It will be confirmed but may take a while.

it depend the last two time i did it, it took me only two hours, not a big deal, if this will be the case in the future i'll use more the no-fee transaction

I sent bitcoin without a fee a few months ago. That transaction was from very old coins, so having very high priority.

to "unlock" these bitcoins you have two options:

1. double spend the transaction (possible only if you have the private key of the transaction's sending address)

2. spend the unconfirmed output with a big fee and hope that a miner will confirm both the transactions (it's impossible to confirm the transaction with the big fee without confirming the previous zero fee transaction)
(I advice using at least 0.0005 btc)

or you can just wait a couple days, if no miner will confirm the tx it probably will be removed like it never existed.

it seems that you will have to wait for a long time

I'm surprised you never sent a fee.  The last few wallets I have had a fee already set up.

I saw your transaction and it is still showing unconfirmed!!!!
Really surprised that why did you sent that transaction without paying any fee.

For the low priority coins, if you want to send them, you have to pay a fee. Otherwise these pools will not include them.

xapo wallet not cut transaction fees
its safe and most securable

It has been market as high priority but seems that today or tomorrow the funds will be sent back to the sender.

I made the same kind of mistake a while back and had to wait 3 days.

Another instance is when I paid a fee of about 12,000 Satoshis on Friday and even that took 7 hours to get the 3 confirmations I needed.

Should go through eventually, or they will be refunded.

couple days +/- couple days :)
It can be long wait, but hey, you didn't pay any fee thats good side :)

This.

It's a bit of a major fail sending bitcoin's without including a fee. The people who ensure the upkeep of the network need to be paid.

I wouldn't expect them to work for free, just include the minimum fee next time please.

Your transaction will be very low priority so it'll either get confirmed or sent back to you, it may take days though.

it take some days to confirm or returned to your wallet like what happen with me once 
i send some BTC to multip address but they returned to me after few days and i resend with fees i got confirmed

Usually it takes some time (may be few days) to get confirmed, otherwise you will receive back this amount normally
But it's not advised to send bitcoin without the transaction fee that's complicate the transaction and make it lower

Greedy miners squabbling over a few stoshis.. The miner market is overbought, the bubble will pop soon..

You can choose to send a transaction without any fee whatsoever. However, this transaction will be left behind by miners because it has no incentive. so miners will be considering this Tx with no priority and it keeps being left behind. Eventually, some miner will pick it to complete a block

Yes still unconfirmed after 4 days. It was my first bitcoin transaction so I did not know a fee was needed. Anytime with future payments I will always add a fee

That will make it much quicker.  One day transaction fee's alone are suspose to pay for BTC I believe (don't know as far as timeline).  But transaction fee really is important.

If you don't do it this is perfect example in most cases long wait.  And it's over a few cents.

Good luck!

I can't wait to hear how long it takes to confirm (or be "returned").

It'll be interesting

0.1 BTC is usually high enough for you to get lucky and confirm the transaction without a fee.

But next time please either send with a fee, or you can use Coinbase or Localbitcoins wallets which both pays the fee for you, for free.

So the priority of the transaction depends on both the transaction size and the fee?

It says that the transaction was made yesterday 14 december, did you made the same mistake again without putting any fee?

Kinda. Priority comes from inputs. Inputs are the coins you have received and now want to spend (create an output). The older (in number of confirmations) and larger (in bitcoin) an input is the higher is its priority. If the whole transaction (can have several inputs and outputs) has not a high enough priority to be confirmed without fee, the fee is a supplement for the missing priority.

High enough is usually 1 bitcoin day. That is 1 input worth 1 btc with 1 days worth of confirmations (144) used to create two outputs. If the input is only 0.1 BTC it would require 1440 (10 days) confirmations, etc.

So then is there a formula for how the fee affects the priority?  So let's say I want my 0.1 BTC transaction to be processed as fast a a 1 BTC transaction would, how much more in fees would I need to add(assuming the coins are the same age)?

No. Keep in mind this is all "default settings" and any miner can change them around however they want.

There are 50KByte per Block that are reserved for free transactions (no fee). They are put in sorted by priority, highest first. Once the 50KByte are filled up the remaining TX are sorted by fee per byte until the block is full or no more transactions are left. The transactions with fees are competing against eachother and those without fees. There is however more space for those that pay a fee. If there are not enough transactions to fill a block, all get confirmed. This would include TX without fee and a low priority as they are at the bottom of the queue.

Since there are always transaction that await a confirmations fees needed to get a quick confirmation are on the rise.

No the transaction was sent on the 10th. But the date seems to of changed on the blockchain. In my bitcoin core client it still says I sent it on the 10th so I don't know what's going on here

I wouldn't advise sending bitcoin without any transaction fee. It would take a long and the transaction may be rejected. There is no point wasting your time and effort just to save a bit of dust.

but it could have a point in the future, 10k satoshi are almost 5 cents, if the price skyrocket above 1k again we can reach easily a range where the fee will not be so cheap anymore, especially if you a lot of small transaction....

You sent 0.1 btc on December 11th with a 0.00033571 btc fee, it confirmed within 1 minute. Today, you send another 0.1 btc from the same address. This time, it really has 0 fee. It should confirm in a few days. Don't worry too much. If you are not sure what you are doing, do not send transactions with zero fee. It's going to cause you problems. Which wallet are you using? Do you know how to attach a fee?

Does it confirm with no fees?

It will confirm because it has high priority in the network.
This transaction ? https://blockchain.info/tx/93e62782951f467afd039d4de969d7dbad7d362ebf6119c40578d3319beac334 ??

If the transaction too long they not come back to sender?

No I sent 0.1 BTC without a fee on the 10th December. I do not know why the date has changed on BLOCKCHAIN.info. it still says the 10th on my CORE client. See image.
The date keeps resetting on the blockchain. Meaning this transaction is NEVER being confirmed. The chain has stolen my bitcoins!!! It's been 8 days with no confirmations.
I know I should now send a fee with a transaction but this is still ridiculous. You should get a warning in the bitcoin client that says miners are tight asses who refuse free transations instead of allowing bitcoin to steal our hard earned cash http://s14.postimg.org/akm6l800x/bit3_Greenshot.png

When transactions aren't confirmed, you client will rebroadcast the transaction again after it was dropped from the unconfirmed pool. In this case, your core client rebroadcasted it yesterday.


The network is fairly busy right now with 7k unconfirmed transactions. My guess is that it will confirm in a week when it has higher priority, could be sooner if you are lucky.


Your coins are still in your 1DBS9 address, it is reported as "spent" because it is used in a transaction. If that transaction never confirms, the 0.1 btc can be released back to "unpsent" status (with a bit of work in core client).

If you are looking for making transactions without fees then you can use coinbase as they pay the fees and will not charge you as long as you do not make tiny transactions

Thanks but I am not looking to make free transactions I just did not realise fees were associated with transactions. It was my first time sending bitcoins and in future I will always add a fee. Just gutted now that I have a never ending transaction that has cost me £32.
That's a very expensive loss for me considering it may never be credited back to my wallet.

I use the main core client because coinbase and other online wallets could close any day and take your bitcoins with them. The risk is too high

Thanks. So if I do something with the bitcoin core client could I get refunded?

If the transaction doesn't get confirmed, you can execute the client with a -zapwallettxes tag. This will remove unconfirmed transactions and scan the blockchain for confirmed transactions.
On Windows, or on mac and linux, use a terminal and enter bitcoin-qt -zapwallettxes. You need to wait for a while for the mempool to drop your transaction.

You cannot sent btc without paying a fee. To be honest, you can send btc without paying any fee but you risk that your transaction will approved after many many many time (something like one day or more), or, btc will return back on the starter address.

Ahhhh that's great you are fantastic! -zapwallettxes worked immediately and credited back to my wallet.
Thanks very much :)

In old times, miners will process transactions without a fee. Now, these guys will not process one without a fee.
