15btc transaction fee, big mistake

[Red-Apple]

This could never happen. Is there any possible way to get back those bitcoins which were considered as the transaction charge. Is anyone heard of such incident other than this?

reading through the previous posts i think it is possible only if the tx was mined with a mining farm and not a shared pool. buy the person should ask the miner to give it back if they choose to do so. there is no other way. (it happened once before too)

looks like there's two more transactions that paid abnormal amount of fee recently. found this at reddit.

both have 4BTC fee. received by blockchain one minute apart. if it's the same guy then they lost 23.5BTC.

I found one of those blocks yesterday by accident. I knew like 4.7 BTC fee in one block was a lot, but I didn't know how to find which transaction caused it (and I didn't want to go through it manually).

I notice something interesting: two transactions with 4 Bitcoin fee, within 29 seconds apart. And one of them is included 10 blocks later than the other.
In other words: does a higher fee really help for a faster transaction? What were those miners thinking skipping this one for so long?

I always believed a higher fee would give a higher priority, but apparently even 4 Bitcoin fee gives no guarantee to be included in the next few blocks!

Good catch! The miners should really check whether the software they are using really prioritizes transactions based on fees, because ignoing such 4BTC fee transaction for so long is simply scandal.

Miners often using their custom software for mining, so does not need to be necessary Bitcoin Core issue.

Which wallet were they using? I think wallets should have a warning system, if you put in too much fee, they should notify you prior to sending the transaction, that the transaction fee is too high, just like some of them do with low fee.

the slow tx spends an input that only got confirmed in block #400850 (link). that's why it's slower.
I guess that proved that there's not many miners are using the CPFP rule.

It happened at least one time before.

Why would someone do that ! Its most likely to be a typing error maybe the person was entering 0.15 BTC or something.

How could that possible is this a human error ,that error is indeed huge i have never had issues on fees I thought it's automated the transaction fee will automatically added to the funds being send,is this error an isolated or will it happen again..

Most often this happens when people dont use wallet clients which taking care of everything. When you create transaction yourselves you might not realize everything you dont use is basically fee. Like if you have 10 BTC and you need pay 3 BTC to someone, you need to send the remaining 7 BTC to yourselves in the same transaction otherwise 7 BTC become a fee. Wallet clients taking care of everything but if you create transaction yourselves you might make such mistake...

Hey,

Can you explain this with a little bit more detail....Maybe, provide some reference links that we can peruse.  It's an interesting application problem, indeed.  Are you saying that those who use a console to push their transaction, rather than the GUI, are more likely to make this mistake?

when someone create a transaction, any btc from the input(s) that is not spent on the output(s) will become the fee. so if you have an input of say 10BTC and create a single output of 5BTC or 2 outputs of 2.5BTC, the rest 5BTC will be set as the fee.

that's why all of the bitcoin transactions spends the rest of the btc to a change address, or the same address, or neither but spends everything.

I am literally crying in front of my computer screen. What retard would do that? I only pay 10 thousand satoshi as my fee and then i see this guy with 15 Bitcoin as his fee. This us just such a sad sight. I wish that I never pressed that link and saw the transaction fee.

This one its worse, accidentally loosing 200 btc is a big amount of money, he had luck that miners returned its fee. I think that we need to look two times whitch fee we are doing, like we do with the bitcoin address (almost i look two times to see if i don't make any mistake writing the address that will receive the bitcoins, and normaly don't look if i made a mistake with the fee).

I'm wondering if this is money laundering.

Alice has dirty bitcoins that can link him to illegal activity.

Bob is a miner.

Bob keeps adding the TX to the blocks he is trying to solve. As soon as he solves the block, he notifies Alice so the TX goes to the network and Bob releases the block.

It looks like Bob got the TX from the network. But the dirty coins are destroyed.

Bob then sends Alice the equivalent value (less a fee) using existing coins or using the coins from the block reward to several addresses controlled by Alice.

Now both Alice and Bob are cleared of any scrutiny and the laundering is complete.

[setupbounds]

Ohhhh that might really hurt you spen 6000+ dollars for a fee

Woot unbelievable, someone just spent $6300 as fees!! I feel i missed something, anyway Lucky miners... 

Damn, how much is the backlog now really?

[WhiteBeard]

Wow! If this is a mistake it is a huge one!   

Otherwise, as has been suggested,  it could have been done on purpose for some motive not known.  Unless the sender acknowledges it publicly we will never know.

hmm, that is an interesting theory but the block was mined by F2Pool i think it was more possible if the block was mined with one of the unknown (other) miners. F2Pool doesn't receive all the fees it is a pool and has to divide the fee to whoever is connected to their pool.

besides this all looks like a lot of work to launder money and expensive too. there are easier ways.

[quentincole32]

I'm looking at it and wow!  Four confirmations....ouch....Is there any imaginable way to reverse that transaction or remedy it in anyway?  Could it have been on purpose?  Some ledger manipulation thing or something, or was just fat fingered?

whoever mined block #400893 and collected the fee can return them if they choose to do so. bitfury did that in the past. (someone correct me if I'm mistaken.)
don't know if that was just a mistake or not.

That was bad side of bitcoin , one click and no matter what transaction has been sent and irreversible.
Unless yeah there is a honest miner who collected that fat fee and the sender was admit it is a mistake. But it's hard to figured out.

i don't think this one is right because the miners fee will be divided to few people who connected in the pool,so,laundering money with this method will end your money distributed to few people and probably bob will just receive small amount of fees except he got a big rigs

You are wrong, f2pool is a PPS pool, they do not distribute funds based on block solves rather shares submitted. If you mine to f2pool you get paid regardless if they find a block, if f2pool gets lucky and finds lots of blocks they profit, if they are unlucky and find few blocks they loose money.

this case was most probably a mistake in the code they were using which sent big fees.
but your theory is interesting but it doesn't sound right. because if you want to launder money you will try to cover your tracks
in this case when Alice sends her dirty bitcoins to Bob and includes a big fee, it is so obvious what they are doing besides doing it a couple of times to a miner called Bob will put Bob in law enforcement watchlist and following the coins going into his blocks and out of his known addresses will lead them to Alice too.

why would he/she do that that is just stupidity, and of that happens to me i wont be able to sleep for a month.
that just hurts losing $6300 just for transaction fees.

Wow! Great story!  Some person attached 25,000$ worth of bitcoin as a fee to his transaction and then he gets a refund.

Like one of the comments says: "Friedcat (apparently the guy who did the refund) might qualify for early sainthood."

[erikalui]

Why did the user even commit such a big mistake? He was transacting such a small amount and he added this fee manually I suppose. It makes no sense if he wanted his transaction to get confirmed soon.

Happy to see that there are miners who make a refund if they receive extra fees.
