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

oh wow, THAT hurts... if i'm reading that right, it was only sending 3 btc or so? i think i'd die.

Why would the fee be so high?  Is this some type of error?

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?

in the past when such has occurred, it was due to someone doing some custom client stuff and making a mistake, or so they said. unless the sender comes forward here, we'll never know.

reversible? nope.

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.

Oh that could not be fun for the stomach or heart watching that happen. Never tinkered with the miner fee and presumed it was somewhat fixed.

It would be real nice if it turned out to be the guy who was flooding the network with spam transactions.

In the transaction to that address just prior to the send there was a receive for the same exact amount....what might be the significance of that transaction?  I don't know; it's starting to look like a manipulation to me.


EDIT: But for what reason?  There's a couple pass throughs with that address.....strange.

yes and others have done the same I think the worst one I saw was 97 coins.  Asicminer aka friedcat returned it.

but my memory is meh don't take it for granted that I am correct.

oh, this is a very expensive mistake, i saw before small mistakes, one time i write 100.000 satoshis for 10.000 (only one 0 mistake) but nothing like 15 btc. He wasted more money on fees than he / she send.

I just hope this is not a mistake that is made by someone who invested a lot of time and money in bitcoin. I can`t imagine doing such a massive mistake and getting over it easily. Hopefully a rich guy messing around to get some attention or for any other "funny" reason.

wow! That is one hefty fee. Ouch.  :o

I feel bad to whoever did this (imagine the moment they realize what they did). Lucky to whoever mined that block (hit the jackpot). I doubt if the person who mined it, would think of return it (unfortunately) unless it's someone that its known at least. Either way hoping for the sender to get it back somehow.

It might seem funny or even fortunate for such luck in that large a transaction fee but Im thinking its a bad mistake for bitcoin overall if this is easily possible.  If such mistakes are made and irreversible by a normal client sending coins it reflects badly on the whole network usage.  I just hope it was a very customised send and probably a company that can write off the loss, hopefully no one person can ever do this while drunk or careless 'fat finger' type mistakes.
  Ive always argued if BTC ever gets big it has to be idiot proof, shed that elitist technical origin if we want the whole world able to use this coin network and its likely a benefit overall

oh wow, just unbelievable! Another bug bounty?

Holy fuck, who would fucking send 3 BTC with 15 BTC in fees? That's unbelievable. Some sort of error, I guess? Perhaps trying to type 0.00015, but instead typing 15 BTC to an unlucky bitcoin owner? :-\

Lucky for whoever mined block #   400893 though, must be a big payoff... ;D

Seems like simple human mistake by a small level trader. I feel sorry for the sender and who have mined the block with that transaction?

That made someone's day! Almost as good as finding a block ;)

Looking at the other transactions associated with that address, it looks like a pass through address.  That whole 22 BTC's was sent just prior to that "fat finger" transaction, and there's another receive-send pair for the entire amount just before that one.  So, it looks manipulated to me.

As i understand it, if some solo loto miner at cksolo pool mined the block, it would be the pool owner ck that picked up the BTC15.  The miner would have the usual BTC25. Not that it happend that way but interesting all the same.

How many individuals solo mine?  Lucky pool owner hay.

why do people make these mistakes. cause this is not the first time nor the highest i have seen ~100BTC fee too, and there is no way someone makes this mistake while using a bitcoin wallet with an interface!

are they doing it by hand, like a code they edited to sign TX like in bot?!

quite possibly. heck, it could have been a bot entirely doing the trade for all we know.

Someone would like make a statement about something? Maybe some miner did it, just to show us normal user, we should all generous about fees.

I guess the sender would be kicking himself as he has lost a hefty amount transacting this transaction

At the same time The pool owner will be blushing himself on getting that much money which he would not have expected even in his wild dreams :)

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

 ::) this mistake is the worst i have seen till now. ouch! a hard bite for the sender who has to pay the 15btc now from his own pocket but what the hell on earth was going in the brain of that user. is it just for popularity or to make loss insted of profit.this type of things became mistry just like satoshi

Yikes, I would not be feeling good right now. What kind of wallet or interface would allow you to do that?  There should be a double pop up confirmation for this or wallet software that can detect if it is clearly a mistake. 

That is going to be one pissed off Russian, if you ask me. It looks like the node being used were somewhere in Russia. Lesson : Never transfer money when you had a little too much Vodka. ^hic^ Why do you think this is
being manipulated? It could just be some typo or someone desperate to get a urgent transaction through. Just last week, I made a mistake in internet banking and I transferred double the amount I owed to a service I had to pay. Now I have to wait 21 days for this service to return the money. It sucks and I feel for this person, because he has to hope some miners takes pity on him and return some of his fee. ^hmmm^  

maybe he is a miners? or control a very large portion of the mining activity, a bit of a joke but it could be  :D

the mining fee is divided proportionally by the hash of the miners right? if you have 1/10 of the hash you get 1/10 of the total fee?

Buying stuff while drunk can make you do those kind of error... ;)

that's unexpectedly funny. ;D
that miner is now enjoying big money with their miners, no matter pool or not. this led to faster block halving however.

I just noticed it, that must hurt for that person. Someone's loss is a win for the other. F2Pool will surely not complain about it. Nowadays there are more and more blocks where the total amount of collected fees exceeds 1BTC. I think one day ago I have seen one block with more than 4BTC in fees.

My guess is that either somebody tried to learn how to make transactions by hand, either he/she thought that's playing on testnet.
However, it seems to be somehow software development related.

Just I cannot imagine who would do tests with such a fat wallet.

No. Only one party (the one mining the block) will get 100% of the money.

Srsly.. I wish I've 30t/h for mine that coin.. 25 plus 15... Omg.. That person could just buy 20 unit s7 foc

wait, how it work with pool then? it must be divided in the end, or the pool get all the money from fees?

At least he got his transaction confirmed quickly. :)

F2Pool will return his money, I guess.

The pool gets all the money (25 BTC+fees) and can then distribute the money to its users. Or not, depending on the pool operator and its rules. This is not part of the bitcoin protocol.

how the hell can someone goes wrong like this in put the fees, there's a possibility that this tx was a sort of test?

I think you're confusing Bitcoin protocol with pool rules. The pool first gets the BTC for the block, and might or might not pay the transaction fees as the part of dividends

Someone would have to confirm the mistake and prove its them.  I think if they did that the miner should return the mistake and show we dont need gov to force moral judgement. Watch this space i guess.

I would guess that they wanted to increase the fee they pay due to the full blocks problem at the moment.  Maybe they wanted 1.5mBTC or even 15mBTC as a fee, but messed it up.

It is a fairly crazy problem to have, on the one hand it is awful for the person who sent it.
On the other hand, they had at least 18BTC, so probably aren't poor!  Hopefully they are very well off and won't miss $6k

Well, a pool will always prefer to include a transaction with such a high fee over a transaction with a normal fee. Especially when the size of the transaction is just 0.23KB. It's peanuts for the pools.

OMG I can not imagine if it happened to me :'(

I do not know how fees could be as big as it was, should not change the fees and let it automatically.

Oh Geeez!!
And the lucky winner is F2Pool!
Congratz gentleman!
A block which includes fees worth 60% of the actual reward.

Oh God this must be the highest fees I have ever seen in a transaction. I think this must be human error and not some script messing up and sending the wrong fees. I hope the sender is doing OK and not taking this too seriously on himself.

that's bad, i thought that the fee's destiny was the same as the reward, they should fix this to prevent centralization of the money when the reward will be worthless


i'm not confusing, i was convinced that the fee were divided like the block reward, and this is not the case then it should be fixed for the future

otherwise how the miners will survive when the block reward will be pointless?

I don't think you understood. The block reward , along with the tx fees goes to the miner who found the block, which in this case is the pool operator. It is up to the pool to then divide and send the miners , their dividends according to their hashrate

... and if the pool operator makes rules that won't give miners any reward, you can rest assured that miners will not mine for the pool. So the problem solves itself using market dynamics :)

I don't know if it's an error or whatever could have happened there, but man, that must hurt real hard, I cannot imagine how would I react with that lost.

Anyway there should be some type of control or fix to prevent more things like that happening..

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..

its a human error i guess, some client have an option to set fees manually and personally for me i accidentaly sent a transaction with .05btc as fee which should be the transaction amount

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...

I feel their pain this morning.  absolute nightmare  :'(

It looks to be a bad starting for the user. How such incident happens. Even most users getting into bitcoin due to its reduced transaction fees. Soon this needs to be rectified. Human won't do such a big mistake.

how it he world is that even possible?

15BTC is $6300

when i want to send $1 i double check everything and then send it, it will only take a second to check!

I would be happy to have 15 BTC and I am pretty sure I will never make this mistake for such a huge amount. I hope the guy/girl haven't had a heart attack when they have seen what they have done.

How could this happen?? I thought all fees deducted by automatic.
Or they put manual fees? Anyway is this your transaction? Feel so hurt when saw this much fees paid.
Can take this back?

i wonder if this person have made an attempt to contact the pool that mined that block. it's no guarantee that they will return anything, but at least its worth a try.

Lol  It will help for them to pay attention to what they're doing next time. If they can mistake a fee its funny to think of the typos they've made sending funds to someone.

He must've clicked on the transaction box in his qt wallet and thought that the numbers there are in Bits and not BTC. Lucky miners who are in a pool who mined that block.

That would be a really big deal if a pool returned the fee.   They arent obliged to but would show an understanding that everyone makes mistakes.  I guess it would be easy enough to just put it back to the original address.    My point is this should not be possible in a correct system, the military have terms for why these events always occur SNAFU basically.  If it can go wrong it will, dont blame the person just dont leave these giant mistakes possible in the normal setup and call it user friendly

Yesterday I found a new block with almost 5 bitcoin in fees (usually it's 0.25 to 0.5 per block), so there too I think someone must have made a huge mistake.

They've created a custom transaction & made a typo error, I'd guess.

Neh, custom transactions 've custom(manual) fee option.

Yep, if the miner # 400893 wants to(agrees), I'd guess (not sure).

---

Basically, this is normal, you know 'coz the (crypto)world is'nt so small.

Wooowww, incredible transaction. I would feel very sick if I have it

wow! for godness sake.
it's unbelieveable fees dude, since i saw it i just cant realize the fees  ??? ??? ???

awesome, i think that there is someone somewhere who didn't wake up from bed yet because is still crying. Maybe the reason was because a bot manage it automatically and crash while was setting the fees, dunno.

Everyone here is talking about human mistake.

But seriously? 15btc fee a mistake?

Well for sure that's an heavy one!
But I wouldn't be so sure it's a mistake. I don't even know how you could do one like that!

to answer this is to understand the difference between a mining pool and a mining farm

a mining farm is a 100% owned by one company and all the ASICS are 100% owned by that company.
a mining pool is individuals, groups and multiple companies working together as a pool/syndicate.

the block was mined by F2pool which is not farm(single entity with 100% ownership of all the asics), but IS a pool.
now to get to the payout part:

F2pool (previously discusfish) has a 4% fee. so F2pool keeps 4% and the other 96% is divided by the shares of the individuals hashing.

eg the reward is 41.13939715, f2pool owner gets 1.64557589 and the rest gets shared out by the other miners.

if it was a mining farm. the entire 41.13939715 would be kept by the farm owner

Hence why there is a test network...

Yeah, the hard fork for the july '17 block size increase should include to prevent this,

Hence why it is wise to wait with a hard fork - it lets you put other stuff in that is needed and do it all at once.

i think i understood correctly, the pool operator can decide to not give anything as a fee concerned, yes he can be seen as a bad pool and none will mine there anymore, but he can still do it when fee will be very important

what i mean is that in the future when fee will be everything, many miners can decide to mine in solo to take all the reward, and not hoping for a pool to split the reward that he own

lol, I don't think F2pool would do it. Lucky pool!

Stuff like this happened once or twice before, pools gave the money back.

I think this dude was thinking he was playing with testnet Bitcoins, but he ended up learning a costly lesson.

looks like there's two more transactions that paid abnormal amount of fee recently. found this at reddit.
https://blockchain.info/tx/c6f9ae3d4e6c895594628a28a53e9c8436a8ba1aaf5f0dd1711ac2a3f4b893c6

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!

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)

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 (https://blockchain.info/tx-index/132693828/1)). 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.

https://www.reddit.com/r/Bitcoin/comments/1lb5my/asicminer_refunds_the_accidental_200_btc/

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?

https://coinb.in/#newTransaction

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.

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

Damn, how much is the backlog now really?

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.

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.

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."

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.

called "dynamic fee" 


:P

That's really hilarious. I wonder how fast it was confirmed.

I feel sorry for the sender.
I guess his drunk or his finger is big like feet.
This is the first time a saw a transaction equivalent to half a million peso.

if you set it automatic fee aren't they kinda dynamic? i means the client choose the best one for the amount you want to spend

he either wanted to make a really expensive joke, or it was just a typo what should have really hurt

I believe that it is a newbie transaction and it was sent by mistake. because there is not understandable reason to through such amount of btc for miners for almost free.
BTW it is not the first time to see a similar transaction, as I remember, two month ago someone send a tx with more than 5 btc as fees

Sadly, the Saint Cat ran away with millions of investor $$ shortly thereafter, so mixed emotions :-\

Alice doesn't have to send them to bob.

Alice can create a transaction send a small amount to a random address neither care about and just include a large TX fee.

Bob just includes the transaction in every block Bob attempts to mine and Alice doesn't send the TX to the network until Bob has found a block.

There's a small risk another miner will find a block at the same time, but really all bob needs is a way to communicate with Alice that Bob solved the block to trigger Alice to send the TX out to the network at the same time Bob releases his block to the network.

Then it looks like Bob got the TX from the network if forensics is done because Alice has sent the TX out to the network.


There's no way to prove any collusion between Alice and Bob through the blockchain and the dirty coins are replaced with fresh coins.

Assuming this was a mistake, I'll echo what others have said here: For mainstream adoption this sort of thing needs to be effectively impossible. Regular folks need clients that simply won't allow this kind of mistake, at least without a series of "Are you sure? Really sure? Really really sure?" questions and/or "Go to Tools/Options/Fees, uncheck boxes for this and that..." type activity.

There is no 800 number you can call to save you with bitcoin. We can hope some miner somewhere does the right thing and returns funds in an apparent case like this, but can't count on it.

People lose bitcoins in a lot of ways, see this topic: How many Bitcoins are lost forever? (https://bitcointalk.org/index.php?topic=1097562), this fee-mistake is just a fraction of what's lost in total.
So why would this be a problem for mainstream adoption? People have been losing cash money for centuries, and cash is still around.

thats crazy, i have never seen something like that, i guess the sender was kinda sad after he sent it

15 bitcoin fees that hurts, that's the reason i don't customize my fees lol i pay the default fees set by the electrum wallet.

Well when i read and say the link ,i thinked no way this has been spent for free ,makes no sense?Is that a kind of test from the developers not announced ?Why would someone throw bitcoin away as its worth 400 and may achive and will go ahead it,sure a mistake and a refund may happen ,but the refund thing were something i believe were impossible at bitcoin,but in this case they refunded the fee and not the transaction soo sounds fair.

someone know who have that transaction? 178.62.211.162 that ip address from netherland,i wonder how about this transaction,is that amount transacted arrive to wallet fully,or lost because that fee,i never see any fees as big like that. someone can explain me how can that transaction have so big fee?

The standard bitcoin-core client prevents this kind of mistake. Other clients may not be as wisely coded though, and I agree it should be in the consensus protocol.

Friedcat was honest enough to refund the fee and it shows he is trustworthy. I know that nobody would have refunded 200 BTC but if it's a mistake, a person has to be kind enough to do it and in this case as well, I hope the miner of the
block refunds 15 BTC as it was clearly a mistake.

Well they can always call customer support and get the charges reversed... oh wait  :(

Surely you can see how this is a problem for bitcoin adoption. The fact that people lose money in many ways doesn't make it any less painful. And this is a preventable cause, so let's prevent it.

Bitcoiners should just avoid making this kind of silly (but costly) mistakes as then they need to pray to God (the only available option) to get it back their bitcoins.

yeah it should be like notification appears before the transaction atleast because i have seen many tx fees mistakes that make you feel for the other person feeling when he does have such a mistake

I suspect Satoshi's hand on this transaction.
Does he start Airdrop bitcoins to the pillars (miners) of bitcoin ecosystem? Anyway, what a day for a lucky miner....

I liked your imagination.
This type of accidental fees happened many times. When I was in dogecoin mining, a large fee (some 200k doges) included transaction block was mined by coinotron, then shared by contributed miners.
Like you said, that also was a airdrop, now I realize.

Ouch that is horrible, hope F2Pool return it and be good Samaritans. But that's unlikely to happen I guess. :\

maybe. what's odd is that so far nobody have come forward and ask F2Pool to kindly return the 15 btc or even a portion of it. we know that this have happened in the past and on half of it the miners were reasonable enough to return the fee.
maybe what AliceWonderMiscreations said is true and this is a money laundering. maybe.

Money laundering with fees? Doesn't really make much sense, the person cannot be sure what pool would mine the block and get the fees.

read the rest of the post and you'll probably understand.
this means that alice and bob is the only people who knows about the transaction until it confirms because alice won't relay it to the rest of the network. of course in this case it would mean that Bob have ties with F2Pool. but like I said, maybe.  ;)

Interesting idea  ;D. Much easier ways to launder bitcoin of course.  They'd have to do it multiple times to make it worth while, and that would look suspicious.

Dammit i would cry if i made such a mistake. It's a lot of money to throw away but just a simple mistake. I bet the previous owner of that btc feels the same way about that.
Damn 15 BTC gone.

Cry i would hurt myself (not to hard) but losing 6K USD for a mistake? Like really? Can't believe the person did not double check this transaction.
I double check every transaction above .05 BTC

Excuse me, I thought I was in a different thread.

 Or even better never use bitcoin because this is what happens if you know nothing about computers and make a silly mistake, they'll comeback that nothing can be done and its your fault anyway so tough.  Should have stuck with dollars and big government nanny state

 This is how a community that wants to expand globally manages to how to shoot itself in the foot by blaming the user who doesnt care about code and technical superiority, they just want to buy something simply.
  The guy who invented microwave was probably pretty clever, but the people who use it just bung the food in there and press 1 button; this is how mass appeal is done sorry

For 6 BTC who gives 15 BTC as fees. I wish like friedcat refunded the fee, the miner this time as well would do the same unless there was some other issue due to which he added such a huge fee.

This seems impractical to me since Bob might have to wait months to find a block, unless he has an absolutely ginormous rig. And if he controls a pool, couldn't Alice just send the 15btc to the pool ? From that point, Bob would just have to extract 15 different btc from the pool at some future time

Ugh. If I did that I'd have to run out and get smashed immediately. Goes to show it's a long way from foolproof yet. I carefully check everything before sending. We need more zeroes on the end and less at the start.

Hey, that are illegal act... :o

That hurts ;D

Wish the guy all the best. be careful next time...

This is not quite true. f2pool is 4% PPS, which means miners receive 96% of the EV of the hashpower they direct to f2pool regardless of f2pool's luck. As long as f2pool has at least 96.001% luck over the long run they will be profitable (before counting other expenses).

My god.......did this really happen? I would be shitting bricks if that happened to me. Man that's ugly!!

gosh... The owner is probably still crying hard. This was the worst mistake of his entire life. Anyway, miners had all the luck and will receive extra coins

Could this really be a mistake or is it possible that this was manipulated?  ???

Also other people reported issues for tx fees (with wallet that they don't know use as good as they need to know...)...
But this is one of the most big tx fees I have never see or ear!

Probably a human error. He must seem to filled the form in a wrong way that he did not notice that the fee he will send have that such big amount. Miners are lucky for that fee. It seems they celebrating for this mistake.

From 22 BTC transfer 15 BTC fee - I think he made the mistake.  Happy BTC miners.  ;)

OMG! 15 btc fee! I wish I could have this money which was a transaction fee only! Never see such a big amount for fee only

Huge mistake, people should be careful when conducting transactions worth thousands of dollars like in this case...

isn't there a slider bar on Core to set the fee/byte of a TX

what happens when you set it to the max?

☑ evidence that it is better to accept the default fee amount

Is this how bitcoin will survive after 2140? People that accidently set Bitcoin tansactin fees too high!

Never set it to the max but it won't result in 15 BTC.

This was either a mistake or money laundering.

I also wonder how Bitcoin ever will be useful for old people. When they now a day can't remember there pin.

what is the max? for fun

From what I know, this is the biggest one in the recent years. Someone might have thought of it as fun to do something silly like this in the early days though

no i mean if you max out the fee slider bar on Core the thingy to set the fee/byte of a TX

what is the max setting for fee/byte on core.


i know this is a little OT but we are 8 pages in...

It adapts to the network. It is not a fixed fee/kb

You as legendary member must know that all depends on how long the coins are sitting in your wallet and the amount of inputs etc. Some times it tells you to pay more than 0.002 if you set the slider bar to the max, and some times it's under 0.001.

dont share this transaction to newbie or newcomer,they will think this transaction oftenly happen in bitcoin transaction. yes that was a mistake,i dont know waht causing that fee. 15 BTC fee is worst fee ever.

Yes when they see such a huge transaction fee, really they'll try to get out of it. But here the miner who did the transaction is the luckiest person to earn such a huge amount through bitcoin.

Holyshit!

Really? I'd die if that ever happened to me... what kind of error could cause that insane fee?

so far i never found transaction fee like that,15BTC fee for 22BTC transaction is not make sense,and i cannot find logic and official explaining about this mistake,did someone know how can this happen?

News about that bitcoin transaction ?

It might have been error or bug in the change system. That is whenever you send BTC to an address, you make a transaction of the full amount with one of the receiving address being your own and receive the 'change' back

I remember Knightdk posting a similar speculation in this thread, which he has deleted possibly as it might be wrong. Can't really post anything more than speculation though

it's just an embarrassing mistake made by some user. why would it get in the news?

he's hoping that maybe he find the pool that has minded the block and they will refund him.
btw I'm sorry for him

Exactly, like the other time (with the 2 btc fee). 


Discus fish mined it....


@--Encrypted--
Would you like to talk about this transaction ?

https://blockchain.info/tx/4ed20e0768124bc67dc684d57941be1482ccdaa45dadb64be12afba8c8554537



200 btc fee.

Just jumped from the first page to this one and I thought I'll faint on 15 btc fees.
Is it really really really irreversible? Double spending won't even help either?
Meh, I doubt anyone will return it back to him

yes is not reversible... absolutely irreversible!  :o

thats bad

oh. you were asking for updates. misunderstood that.  :P
well there's this reddit post (https://www.reddit.com/r/Bitcoin/comments/48p1bk/somebody_sent_a_transaction_with_a_15btc_fee/) but that's it. no refund and no owner requesting it (in public, at least.).



I wasn't even around at that time. can't find discussion about it with the owner posting in it and requesting a refund, but the address the fee was returned to wasn't a part of that tx so I think they did request it.
interesting thing is that people also suggested that it was a money laundering.

This kind of mistake could be prevented in the consensus protocol but the core devs don't want to. They think protection belongs in the client. However clients have bugs and not all users know to look for clients that have this kind of protection, it's not something advertised on feature pages.

The protocol should reject blocks that have transactions with grossly large fees in them, that way if a miner includes such a tx the block is rejected, and the tx never happens protecting the user.

But core devs don't want it, and moderator of dev list doesn't allow open discussion to try and change their minds.

Its crazy we do not have some guy ranting about his fee somewhere on the net that would be able to verify.
If I paid 15 or 200 I would be pretty close to needing to call for first aid,heart attack would surly be incoming.

Any other links or news,please update this issue.

yeah i think they will be very hapy with that fee :D

well it is how it is, it must have been a really painful thing to do and the sender most probably was very mad about it

though the miner who found the block must have been very happy, it is nearly the same amount of bitcoins you get for mining a regular block

Whoever mined that block is likely going to be very, very happy with their luck and enjoy a nice, what would that be, ~60% bonus?

That or some mining-pool owner just got himself a nice amount to spend.

Mined by 'Discus Fish (F2Pool)'.

It's possible it was the miner himself or herself and wasn't an accident.

Is there evidence the TX hit the network before it was in a block?

Mmm.. but how the miner know that himself will mine/found (for sure -a t 100%) that block ?

What exactly do you mean by that? All transactions are broadcast on the network before they're included in a block.

Yeah. They wouldn't really gamble on the chance to mine the block - it only takes one hash to get that reward, and there's no guarantee that any miner would be able to get the reward.

The miner could put the TX in every block they attempt to mine without the TX being on the network for other miners.

That's how large TX fees can be used for money laundering.

A Chinese pool too, they seem to have all the luck these days. Must have been nice to see another $6000 pop up along with the normal 25BTC

Probably there should be a warning message coded into all bitcoin wallets that warns users to not pay more than say 0.05 BTC as fee, and warn them twice if they try to send more.

That should help morons like this.


But there is the saying:  "A fool and his money are soon parted"

The protocol should just block absurdly high TX fees.

Count the fees for the last 20 blocks, divide that by the bytes used for transactions, multiply result by, say, 25. If the TX fee per byte is bigger than that, it isn't a valid transaction and a block that includes it is not a valid block.

Would be adaptive and would not be too difficult to implement and would protect users.

25 may not be the right number, I have no clue, would have to watch the chain for a few weeks to pick a multiplication factor that clearly indicates an absurdly high fee. Not just a high fee, absurdly high.

Thats too complex and needs manual adjusting, plus protocol changes need hard fork , and we wont do that for a few idiots.

It's just simple if you add a code in all wallets to warn you twice or even 3 times, if you want to send fee's larger than 0.05BTC, because it's likely that you wont need to send higher than that in the foreseeable future.

Not too complex and needs no manual adjustment, it would auto-adjust based on the last 20 blocks.

Yes it would require a hard fork, which is why it should be done at the same time as another issue being fixed by hard fork - say the block size.

Adding code to wallets assumes the wallet won't have bugs. Wallets have had serious bugs before. Protocol protects the users from wallets that have bugs. Or wallets that don't implement it.

Protocol level also removes one of the easiest methods of money laundering in bitcoin at the same time. Well easiest if you are a miner.

Have some malware that steals bitcoin? No problem. Stick them all in a transaction with a small fee to a burn address and a large TX fee. Now the money has been laundered and can't be traced through the blockchain. No need to trust mixers. That's what we have right now.

its just a donation lol, im pretty sure it wasnt a mistake. as hard to believe as it sounds. people usually choose custom transaction fee just to support the bitcoin miners.

This is a raw transaction fuckup, no doubt about it.

Poor miners with F2Pool too, according to the Bitcoin wiki F2Pool doesn't share fees with them.

Wow I can't believe that someone spend 6300$ whorth of bitcoin on the transaction fee

Easiest way to do this would be for the wallet software to start rejecting too large transactions. Ofcourse, the big boys could easily compile their own version and go around this, but atleast it would filter out the real accidental large sends.

Also, I don't believe for 1 second a transaction like this is accidental. Even if they would've switched the amount and the transaction fee, they still wouldve sent 6 btc as a fee..

I don't think it is the most effective way for money laundering, as the tx fees are split through all the miners on the pool. Even if you ensure the tx ends up in a block you mine, you still share it unless you are the sole miner on the pool.

I'm rather surprised someone that has that much made a mistake like that, even with brain wallets sending the remaining balance as fees that would be awful mistake not knowing about the wallet you are using... few thousands dollars more for the miners for free.

Oh God. its shocked. why this happened ? is there any solution for this mistake or he will serve with it?

having large amount of btc or any kind of money does not mean that they know what they're dealing with. the one who sent that tx could be a newcomer fresh out of the ignorance phase.

That hurts a lot.
Any informations on how this happened?
Users fault or some technical/software issue?

it look annoying even for someone not involved with the transaction, check the fees field better....

Ah this is a really good question!
But how we can reply to this? Because it's a anonymous protocol and we can't ask to sender.

You could use the geolocator on the whois and blockchain to find it.

You can rule out everyone on the forum (if it was them they would say).

the sending app should always alert people if they write too high value into the fee.

And the protocol should protect people when the sending app fails to do so.

wow, miners are happy, user not so much. how could that happen

Big mistake indeed, these people should be more careful when conducting transactions worth more than $7000 USD...

Too much to be wasted on a stupid mistake, Seriously wasting $6,000 because they used brainwallet or because they did not check the fees field carefully is annoying, maybe they were able to get it back from the mining pool?

a very big mistake, it's almost worth $6000 of value lost in this transaction, People should be more careful when conducting transactions of this value.

I just can't believe someone inserted a wrong number in the fees field, Huge fees and can't be intentional IMO.

Now i will be so attentive when i am doing a transaction. Really? :o ~6000$
Will chek twice next time.

oh my god !! that a high fee. Does anyone has chart of fees on how much fee is deducted on particular amount of transaction. Miners will be happy with that, after all they also need a reward for doing this hard work of mining.

I'm rather surprised someone that has that much made a mistake like that, even with brain wallets sending the remaining balance as fees that would be awful mistake not knowing about the wallet you are using... few thousands dollars more for the miners for free.

That's just annoying to look at, $6000 For the miners for free and an expensive mistake, People should be careful with amounts of money like these.

Which wallets offer this or how do I protect myself from unloading my savings in a transfer?
Checked the wallets I use and all pretty much have protection from this.

no wallet should do this unless you modify a wallet's source code and made a mistake.
and this could also happen because of the sender forgot to add an output while making a raw transaction manually.

.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?

You can't reverse a confirmed transaction. All they can do is contact the miner/mining pool, prove their identity by signing a message with the sending key, and ask pretty-please-can-I-have-my-bitcoin-back? There have been some major cases where that has been done (kudos to the miners!), but it gets more tiresome every time this happens and I can understand if they draw the line somewhere.

I'll say it AGAIN - the authors of wallets need to hardcode limits on the transaction fees to flatly prevent someone from accidently plugging in an absurdly high fee. If someone ever does want to send something with a huge fee let them use a custom wallet or tool to do it. The rest of us don't need the "ability" to send a transaction with a fee of higher than, say, 0.1 BTC.

No, it should not.

That's not very encouraging. 15 btc overpay now... What's to stop a 150 BTC overpay happening later. 1500 BTC? Could change everything.

There was a 291 BTC payment to send .0001 BTC just a little over a week ago. Last I heard the miners were looking for the sender to refund the money, but no one had come forward. There was an article on Coindesk about it, and someone noticed the transaction and started a thread here about it.

If no one has come forward, maybe it was crime related. IDK, can't imagine anyone brushing off 291 BTC. Who sends .0001 when you have that much anyway? Might have been an exploit/intentional.

it was not a problem for me because I have not bitcoin too big in my wallet So even if the fee of it. I could not afford or may be insufficent funds Lol

not the protocol but the wallets for common people should.

Unless it was somehow intentional, but I can't think about a reason for someone send 15 BTC txt fee by mistake

Thats a too high fee

The fees so high if im the sender of that bitcoin i would not using anymore in the site that he/she using. What is her/his bitcoin wallet site? I need to change my wallet so that it will never happen to me. This is Error of site or not? How about he refund hes bitcoin is that possible?

it was very large, and why is it always exceeds the number of shipments, as was the case previously only sent 0.0001 with fee of about 291BTC

aww,its hurts,another mistake from pool?is this third transaction that have big fee and bigger than amount transacted?
someone siad this is not first time and not last time,i will wait for another mistakes,i wish not happen to me ;D

It has been quite old but any news if guy got contacted on getting it back or something?

They could just return the money, although that has a risk as the address can be abandoned by the owner already. Maybe they can send a small amount back to the address the 291 BTC came from to draw some attention.

Isn't there a testnet mode to conveniently try stuff that you are coding without risking losing BTC? I think there is.
If this was a mistake, whoever made this mistake must have tons of BTC, I think when this happens it's usually whales that don't care that much because they have tons of BTC. There is no other explanation. Anyone of us regular folks with regular wallets, would check x10 times before sending any custom fees.

Definitely big. The irreversability of btc transaction makes it a double edged sword. 15 btc can already buy a mini car :)

Not as big as https://blockchain.info/tx/cc455ae816e6cdafdb58d54e35d4f46d860047458eacf1c7405dc634631c570d :)

What's dead may never die.

Nobody can reverse that transaction. Some lucky bastard got a nice piece out of this. Mining has to be rewarded sometimes.

Rip that dude.

15 BTC is a huge loss, especially when used as a transaction fee. Considering it is just going to go the miners, though, it is probably a better outcome than sending it to the wrong address, where it could be lost forever.

There seems to be a number of these issues recently, maybe people need to start paying more attention.

That's a big mistake, these were mostly due to human error. Recently one of the Coinbase user has transacted 0.0001 with a transaction fee of 291btc.

Damn, so big mistake, but we all a humans and everybody doing mistakes, shit happens and next time need to chek everythig twice before confirm a transaction.

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?

I think it was not a mistake, kind of in intention for sending just 0.0001 btc over 200+ btc fees. He/she did it for a fantastic giveaway for miners OR maybe someone ( not the owner ) did it on purpose, kind of revenge to the owner? . Lucky miner who got the block :)

Yeah i think that's right sir its intentional..but we can't do trace it because bitcoin users are anonymous ,but how does that it happen when he sends a btc .

   First I couldnt believe, then I have read all the comments, and I still cant believe in this fees. This must be some kind of manipulation like Cjmols mentioned on the beginning of this discussion.


   I`m glad that some miners are good people, and if they can return this accidental fees its good explanation for couple cases, but what is with other similar cases? Can they manipulate system in that way? If they can that is very serious matter. I didnt see any logical answer why fees are so high for this people.

   Can this happen to anyone? I mean is there some wallet where this is impossible to happen?

It happens because some people think they are using the test net system where they try out things, or they were trying to create a raw transaction where they messed up things. If you do it the wrong way where you select just one transaction ID, it will use the rest of your balance automatically as fee. If the rest of your balance is 0.1 BTC, then that will be the fee. If the rest of your balance is 100 BTC, then that will be the fee. That's why you must double check everything before sending.

This should have never happen. I mean its software fault, there should be safe procedures for that.
If fee is higher than amount spent, block it :(

This is possibly some error done by the software or by the sender. Such fees could only be possible if you send tens of thousand of bitcoins in one transaction. The miners are very lucky if they received 15 btc in one go.

This is a shocking reality in bitcoin reality and has happened once in a lifetime. This should be recorded in bitcoin history as the highest bitcoin transaction fee ever recorded.

I just wondering , how can this type of mistake possible? I think fee are automatically being charged right. This is such huge huge mistake ever , I can't even imagine if that was me. Pheww. Looking at current btc price and 15 btc as fee. I'm going to shop and buy myself a rope. LoL !

The fee is whatever is left from the inputs that is not spent. If you are using some a wallet this shouldn't happen unless there is a bug.

Wow, what a huge amount! This guy spent fortune for a fee. But how this could even happen, unless is some kind of bug. The fee is way to big for amount spent so transaction couldn't even be executed. Or am I wrong?  Anyway, this was one in a time lucky event for miners.

MAy be someone made a mistake by putting 15 btc fees instead of 15 Mbtc (noob mistake ?)

How noob can someone be to spend.. umm almost $16.000 on fees? We are talking about tens of thousands here. That guy either really didn't know about Bitcoin too much, a kid played with his phone or he wanted to vanish his black money and didn't know what to do, lol. But I am almost 100% sure he didn't do it by mistake. I would be careful with every step I take if I were him.

Well first of all it might not have been a mistake at all. It might have been some flamboyant person trying to show off their stash of bitcoins. They might be the owner of a mining pool, confident that they would mine the next block and get the rewards anyways.

Also fees can be manually set or could be automatically adjusted if you are using an online or desktop bitcoin client.

But yes, if it was a mistake $15,000 isn't a small amonut...

That what I thought , I've faced this kind of problem but not bug. There Android wallet where u can enter your own amount of fees by your own desire. So it's all manual not auto like these days. This 15 btc fee happen long time ago. Maybe 2-3 years ago if I'm not mistaken. Well sorry to hear his biggest mistake ever. Now when he look back at his mistake , I bet he can't really sleep well hehehe 😂😂

I bet he sleeps better than the poor people who mined btc back in the day and can find their wallets. I remember reading a story about someone searching through a landfill for his hard drive because it has a $1 million worth of btc on it.

Phew that alot of btc , imagine that Bitcoin by now , double or possibly triple. By the way did he manage to pull out his lost wallet in landfill lol?

Fees can be set manually if you desire that way you can decide if you want to add a big fee to get a very fast confirmation, or you can send a low fee if time is not really important, I think it was a mistake of someone who was new to sending bitcoins, that is why, even if you have lots of bitcoins you need to send a very low transaction first as a test.

That what I thought, maybe he little bit confused with the fee and the total amount he/she supposed to send. Or maybe he/she not really good at English. This person actually from China of I'm not mistaken. I've watched someone from YouTube talk about this huge mistake ever in Bitcoin fee transaction LOL. 😆

I think a mistake just happen, If I am the sender I will surely be very awful because If I sent the 15 btc for just the transaction fee it is a very big mistake , The miners is surely lucky about this transaction but the sender is surely disappointed with the mistake happened.

If this person set 15 btc as the transaction fee, then how much was being sent? Am guessing they sent 0.002 btc or something less as the mistakenly swapped the two  because that's the only logical explanation I have come up with.

If you are not agreeing with the default tx fee, then you need to be extra-careful. Had this guy used the default fee, then at the most he might have paid BTC0.001 or BTC0.002 as the transaction fee. He tried to lower it, and as a result lost all his coins.

So what happened in the end? Did the miners reimbursed the coins to the person? Or they kept it?

It happens when you dont know to count which i dont believe having this much coins in their arsenal or forget using the googles ,always use power glasses while sending coins if you are blind or ask for assistance . :D to send 3 BTC he sent 15.6 BTC what a funny story it would have being.

That is very sad for whoever sent such a large fee. I wonder if the fee was put in manually or it was an error caused in the blockchain. Whatever it was I really feel bad for the unfortunate person who paid the chunky fee.

This is unfortunate that happened due to mistakes due to carelessness. Somehow it has benefited the miners and the user seems to be the unluckiest person. If he had lost through gambling he could have not worried much, because already everyone know the risk of gambling.

There is no charge back function if you do some blunders and that is how bitcoin works.This might be a test done by the developers to check how things go and i am sure no one with sane mind would do these kind of things.

As long as it only returns the fees to the sender for a specific amount and still left the required minimum fees then it's fine otherwise if the thing works like PayPal's chargeback it might be a bad idea.
And unfortunately it seem that this feature is just never be implemented into bitcoin though, just my 2 cents

Yeah I'm having the same thought, this has happened a long time ago, at least it's enough for bitcoin's price to go sky high, and I can't even imagine how much 15 bitcoin is right now. I mean if I ever made such mistake, it would strike me down and I think I wouldn't live for long :'( Anyways I have a deep sorrow for that man, it must have been a difficult time for him to gain back what've lost.

 

wow , I was very fascinated by this, 1.5 BTC for fee

There is nothing to be sorry for.At the time it does mean shit to him and the valuation at that time was such it doesnt mean you lost much .No one expected the price to rise like this and if anyone had any clue everyone would be jumping on to this ship on hearing about it in the first place and i am sure no one does that.

Blockchain do not forgive dumb actions. There is no way back.

You have to check all of your bitcoin related actions twice before you execute them. (you better check them triple if you have a weak memory or experienced a situation like the one in the topic title in the past.)

You may do a mistake while using regular banking and ask for their help but not with blockchain. No customer service here.

OMG That so much sux bad. I hope the person that had to pay for that whopper fee didn't have a heart problem and ticker failure. I think I would have been mortified lol if that was me.

ahaah, are you sure that they are doing something bad thing ..?? . I think that all the things said is not something the right thing, or it could be said that all the data he found was real because it is derived from transaction data mining or not of giving someone a fee. So think properly, and never try or do it. Because a seller that success comes from the way he offers products and talk with others. If we could read every utterance and its views, then there are lots of benefits
 

If someone doing such transaction I don't he is small holder of btc us (me). I think he already covering up what he have lost. Now that 15 btc is more than 15k USD. Phew phew phew. Hope he won't looking back at the past lol 😂

Yea , this (btc) actually money for programmer. Who know this Bitcoin currency now is THE KING OF ALL CURRENCIES in the world. 1btc = 1024USD nobody know 😉

Damn! That is one hell of mistake and the miner who got to process the transaction is one lucky bastard! Imagine if a solo miner got to process this transaction, he could have got the entire ROI from this single transaction.

If you thought this 15 btc was the worst nightmare you ever heard of , now watch this one. He lost 7000 BTC in landfill ! https://youtu.be/0tMXLDVpPs8 now this ridiculous!

I am not in expert in mining but few months ago, I read a post about someone (he is Bitcointalk member) and he actually spent around 111 BTC or something as fees but he did something with an expert and eventually got back his money.
