Why is my transaction still unconfirmed? I have sent 0.06 to Bitmixer.io and it's unconfirmed for more than 9 hours, but address will stop working in 3 hours! I don't want to lose my coins, so.. Is there any way to get them back?

You have a low fee and there is an ongoing spam attack that is causing delays. Just wait a while for it to confirm. If you don't receive your Bitcoin when you should, contact their support and be sure that you have the letter of guarantee. Since they are a legitimate service, they should still send you the Bitcoin even after the time is up.

Calm down! Just wait a while! You wouldn't lose your bitcoin and the networkd will drop unconfirmed transactions out of the memorypool after 1008 blocks (~1 week) automatically. Or try the method mentioned by the upper user.

...

bitmixer.io is indeed a legitimate service, I have used them many times.

My best guess is that transactions of very low amounts (and especially very low fees) are the ones with looooong confirmation times.  

Two examples:

1)  A few days ago bitmixer sent a small payment to ME, but it took some 40 + hours to confirm (as they sent the payment with a close to $0.00 miner's fee).  I did get it confirmed, but it took a long time.

2)  As a test during perhaps the worst of the "stress test" / spamming / attack (July 6), I sent myself a small transaction of about BTC0.005, but with a large fee: BTC0.0006 ($0.16).  The transaction was confirmed on the next block.  Reconfirmed on the one after that.

Notice the pattern?  Be a tiny bit generous, and you get your payments confirmed.  Be really stingy, and the miners will not bother confirming you when THEY are under attack as well, and not getting any payment.......

these recent attacks on the bitcoin network is getting out of hand. it is becomming everyday event and it is hurting everyone . the only thing there is for you to do is that you can contact their support with your information and ask them to extend the 3 hour period.
i am sure if you provide this information to their support they are going to help you out.

I heard today bitcoin network was attacked by spam transaction. Try to increase your fee to 0.0003 or 0.0005 to prevent delay. There are 19591 unconfirmed transactions right now. Unconfirmed transaction increase quickly, so increase your tx fee may help you. https://blockchain.info/unconfirmed-transactions (https://blockchain.info/unconfirmed-transactions)

even the blockchain suggest like that https://twitter.com/blockchain/status/618780981567295488
increase your tx fee then will make your transaction comfirmed faster than usual

0.0001 BTC

should have paid 0.00020001

Could be a miners cartel forming to increase the block values.. Won't be surprised if this keeps going from now on, forcing all of us to pay higher fees..

You and 14 000 others. I am getting fed up with this situation. At least it looks like it's stopped, now just have to wait until the backlog clears...

Just pay 0.0001 per kb and you are fine. I am sick of these people complaining their tx is stuck. Just follow the bitcoin core policy and pay 0.0001 per kb. Time for alternativ client developers to adjust their fee settings.

Just tried it, tx got confirmed within 1 block.

How is this not getting confirmed?

The block bellow has 2 transactions on it... I don't understand why it didn't confirm his as well?

Haha, I know it may be a bit far fetched, but this type of stuff happens all over the world since forever.. Why not in bitcoin? I don't mind actually, as I think the miners deserve the fee and therefore always pay the recommended fee.

yeah, there are also people saying bitcoin is broken, just because their tx didn't confirm within 10 minutes block time. but we're here to help. if some one doesn't know, just explain it to him. next time he's good to go.

fee was a little bit low, and it seems it is not going to be confirmed soon..

And again empty Block #364550

Basically you're right. The problem is that people will most likely use the default setting of their wallet for fees. If that isn't adjusted to the current situation, the transaction won't be confirmed.

It's the sudden onset of these spam attacks that make them problematic: A transaction might have been sent with a fee which was adequate at the time of sending, but reaches the mempool at roughly the same time of the attack with the result that the fee is no longer adequate.

What in the serious fuck?!

Why are the miners ignoring paid transactions?

11 minutes between blocks and it didn't pick up 1 transaction?!  I've been waiting for hours...........

How about calming down first? Every now and then there is a empty block, and this particular one was generated by a unknown entity,hence the IP address.
If you have included the proper fee it should be very quick. Please read this thread  (https://bitcointalk.org/index.php?topic=1085800.0)from start to end to understand some of it.

That is right. I always pay the right amount of fee and get confirmation quickly.

I have 1 that has been out there for over 2 days (yes the transaction fee is low), the other has been a high priority for over a day.  TX=af0b0314687dccefd7a93a8c743723935e6c995e416e5502e9719d4ccfec9056

It doesn't have a low fee warning.  But I have adjusted my fee to what has been posted as standard here.

I've got the same shit. 2 BTC withdrawn from poloniex is stuck. Tx: a2ee8ad3d201954b502733fa0697c6761b38ee67a4f9f51a8b307142dfbdbe27
The block size must be increased!

Last days many people are having issues with bitcoin transactions. Including me also.
This "stress" test should be stop and everything must go back normal

i'm using the standard fee of 10k and no issue so far, i performed some microtransactions, everything was good in less than 1 hours, maybe just luck...

Some safeguards need building into the Bitcoin wallets to prevent this type of spam attack working in the future. There will be endless copycat attacks now it's been demonstrated to work and have a serious effect on the network. Has there been any word from the core devs about a fix yet?

That's nothing. There was a reported unconfirmed transaction that got stuck for 17+ hours reported here in the forums (can't find the thread right now but it should be easy to find) so don't be surprised if it takes an entire day for it for confirmations to start happening.

This one has been unconfirmed since the 6th.  fb402d240f1258a472f7ecca00b62994165620a7168ce19f80f4b8bddbe7b6ec

Yes I know the TX fees were screwed up.  I usually go by what the client thinks it should use.  That has been changed.

3 days and waiting for this one to confirm

c3c13053f54101413e2e638ccf0e3be32956e7e0e2c95451bd9996da84723128-000

Yeah thanks for the heads up guys, I have been having slow transactions too.  I guess I just need to bump up the fee a little bit to get my stuff to go through.

This is so silly!  What did they think would happen with the stress test!  Just wait, the backlog should clear soon.

Just looked out the window, no flying pigs yet!!!  :D

It is not 3 days, it shows that today was made that transaction:
Medium Priority because of the low fee
Fees    0.00000375 BTC

That is not a solution.  It's really not a spam attack can be done on a 100mB blocks

Same thing for me. Did a 0.021btc transaction. No confirmation. Almost 24+hours. Did add miners fee. About 10k sat. Medium priority :/

I m waiting for 75 hours now and still nothing.one exchange sent me 0.9 btc three days ago and theres not even one confirmation yet.

I think this post is worth paying attention to. I think it is really important to that people start realize that there is connection between the chance of your tx to be added to a found block and the size of the tx fee. It is really up to the miners if they want to add your tx to the block or not, but a high fee will really increase your chance. I have noticed that when cyber-bank-robbers steal bitcoins from the bticoins exhance then do they use 1 BTC in tx fee, in these case then was the tx included in very next block. Not saying you should pay that much, but if you have a tx where the addresss is valid for a time limited time, then pay a good extra fee, in the case in OP, then would I have paid 0.005.

I guess we have a lot of people not understanding that with this volume of transactions the only things that's going to get you moving is paying higher fees, well at lease .0002 to .0009 for a transactions is my experience so far when i needed to send bitcoin and its working.

I feel that blockchain is having an issue as 0.0001 BTC is their normal fee and still the transaction is unconfirmed so in this case even setting a higher fee won't work. You need to wait till blockchain is back to normal.

It feels like the miners are just straight out ignoring anything under a .0005 fee.

Shouldn't ever wallet have an automatic transaction fee suggested in terms of the volume of the network to avoid this? in core we have automatic suggested transactions, even tho i think i always used the fixed 0.0001 one

Been waiting 51 hours now and suddenly my transaction is gone from blockchain.info  ??? 

Those of you who are old enough to remeber the days before internet know the feeling of wondering where my money is traveling at the moment. Sending cash in the mail was high risk sport... ;D

That is ok and normal. Any unconfirmed transaction will be dropped from the network and "forgotten" after a few days. The Bitcoin is safe, and you can just resend the transaction with a higher fee so that it can actually be confirmed.

If it's dropped from the network how do you the get BTC back in your wallet?

What is the best fee amount when we send bitcoins from one wallet to another one.
I really hate now transactions, when i see people waiting for days.

It is as if it never left the wallet. If a transaction is dropped, it is as if the transaction never existed so the Bitcoin remains as if the transaction never happened.

I haven't sent transactions during this time, so I can't really say. But if I do send transactions, it will be double what Bitcoin Core defaults to recommending e.g. 0.0002 per Kb instead of 0.0001 per Kb.

hmm,  maybe about 80% or 90% of the ppl in this thread are throwing out wrong info

anyway, this 'priority' you see, doesn't really matter.  do any pools actually set aside kb for priority?  i doubt it

and I would pay .000100001 per kb

I think there is a problem with very small transcation in bitcoin right now. I try to do similar with 0.001 and after 6 hours this transaction has 0 confirmation. I had pay a normal fee for this and was 0.00001. I think is not good for the bitcoin network and payment system to drop and block the small transaction because it seems that this happens now the system completely block that kind of micropayments.

Mine finally cleared!!  WOOT!!

Mostly if you have patient confirmations will get through, even with auto fees your most likely to get one confirmation after 6 to 8 hours boost them and it would be just like a normal day in the bitcoin office.

I've heard if the transaction isn't confirmed in 24 hours it's dropped from the mempool and should be spendable again. Is this how it works?

no i believe that is not how it works.  someone correct me? 
someone suggested that it SHOULD be this way and i would agree except spammer dust should be burned and lost or converted to fees in the block.

i understand what bitmixer is for but can someone explain to me what the possible need or use case is for mixing 0.06 btc?

lol

It does that after 48 hours or more, not 24 hours. Eventually, an unconfirmed transaction is dropped after a few days unless someone (e.g. the sender) continues to broadcast it.

I saw a guy here waiting for something ridiculous like 30 hours, and the transaction finally went thought. He never received the money back after 24h, he just waited more.

I had one go for 3 days.  Then it finally confirmed.

I see many people used low transaction fees and they had delay on confirmation. So must be careful these days

After how many hours? what was your fee? I am waiting on 0.09btc with a fee of 1114 satoshis for 96 hours now.

next time do it with 10k, because all my microtransacstions that i've done recently were all confirmed within an hour

10k satoshi is still nothing, you can't expect a good confirmation time with 1k and the current "attack test"

similar issue resolved here https://bitcointalk.org/index.php?topic=1097735.0 (https://bitcointalk.org/index.php?topic=1097735.0) hope helps.

Looks pretty bad for winbits.us, the transaction is still unconfirmed.
I guess it will eventually be dropped from the network, and then will winbits.us be able to spend the coins again.

Load a backup wallet you didn't do that TX on.

What the hell, still unconfirmed?

Oh yeeah.. :( I smell bad luck  :D

Blockcypher will give you the "your screwed" odds.

Right now your are 72.62% screwed (though I think the numbers are made up)

It's only $17, but if you really want it you could gamble another TXO on a CPFP sweep.  I'd caution against it unless you happen to have a TXO that is $2 or something.  Anyway... I would think a 10 mBTC bounty could possibly get you in a future Eligius block.

Ah. Thanks for the infos!

I've had 2 transactions this week. One went fine and fast, the other remains unconfirmed after 49 hours. Something needs to be done. Increase block size, increase the minimum fee, increase the minimal amount to make a transaction... I'm not enough of a techie to know which solution is the best, but something needs to be done!

Imagine the post office deciding to forward only the letters with extra stamps and, after a few days, just sending the rest back. Peculiar. :-\

This needs to be debated once the spam attack stops. A stop gap solution implemented now to deal with the situation may not really present the best situation. This attack may be good for Bitcoin in the long run, if it forces some changes.

WTF? ARE YOU FUCKING KIDDING ME? IT RETURNED TO MY WALLET AND IT WAS AUTOMATICALLY SEND AGAIN!

CHECK THE TX AND DATE WHEN IT WAS SENT! IT'S TODAYS DATE, RIGHT. AM I TIME TRAVELING LOL?

KEEP MY $20, I DON'T CARE, FUCK THIS BULLSHIT.

Well, now, with this changed date you will not be able to take your BTC from Bitmixer even with your letter of guarantee, right?
That sucks man.

pay the fees.



i have doing a transaction flawless this day with ... 0.00015 BTC of fees.
(coin destroyed = 39 days)




no problem at all.
stop use the checkbox "pay without fees".

What should I do when it comes back into my wallet again? Send it to my second address?

pay the fees.

http://bitcoinexchangerate.org/fees

Apparently your transaction has been rebroadcast to the network, either by your wallet or someone else. Which wallet client do you use?

This is a current issue with transaction getting delayed for so many hours mainly due to low number of peers seeing it, however increasing the tx fee should make confirm times faster, but doesn't sound like a more feasible option considering the thousands of transactions happening every single day.

I'm using Blockchain.info.. it came into my wallet and it was here for some time, but it was automatically send again.. Please help me :(


Go fuck yourself shitty scumbag. You didn't even check the tx.

Well then the transaction was rebroadcast by someone else, as otherwise the "Relayed by" field should show blockchain.info.
There is no way you can stop someone else from rebroadcasting your transaction AFAIK, so you should send it to your another address once it comes back to you.

;D i love noobs.

Bitcoin is not a friend ... if you don't play by the rules, you wait (like others).

This probably won't work for him.. I don't how it works, but when he sends something, it comes back and it's automatically send again, how can he send it to an another address? Or am I missing something?

He could contact the admin and request for a cancellation of that particular transaction. Although there are no guarantees that it will be granted, still worth the try.

That sucks.

haha that is too funny.

My best guess is that transactions of very low amounts (and especially very low fees) are the ones with looooong confirmation times. 

Two examples:

1)  A few days ago bitmixer sent a small payment to ME, but it took some 40 + hours to confirm (as they sent the payment with a close to $0.00 miner's fee).  I did get it confirmed, but it took a long time.

2)  As a test during perhaps the worst of the "stress test" / spamming / attack (July 6), I sent myself a small transaction of about BTC0.005, but with a large fee: BTC0.0006 ($0.16).  The transaction was confirmed on the next block.  Reconfirmed on the one after that.

It was probably that the mempool was full of high transaction fee transactions. I usually have no care in the world about how long my TX takes. 0.0001 usually works for me.


1) Can you give proof of that? Because I know for one that bitmixer.io is not stupid enough to pay a 0 TX fees.

2) Why the heck are you wasting 0.0006 BTC on a test? This site (http://www.cointape.com/#delay) actually tells what's a good TX fee for free.

I'm having a hard time believing you, mate. I can't help to think that you're lying.

Try to set your transaction fee to 10,000 satoshi. Then try again.

If you haven't noticed this post is made 3 months ago and has been resolved. No point in bumping old threads like this.

This also happens to me, you just have to wait and soon it will be confirmed. You are only transferring a small amount of Bitcoin and you also put low fees. So miners don't really want to mine your transaction as they wouldn't really earn much, they can just mine another transaction that will earn them more Bitcoin. Also, I don't really know if you can get your coins back, I doubt that you can though.

If you actually bothered to click on the transaction ID written on the OP you'll be amazed to find that the transaction already has over 10k confirmations  :o

you are unlucky,just contact blockchain now..i also ever happe to me
