Topic: Think twice before pressing send. - page 2. (Read 528 times)
Unfortunate, but you must be careful with all financial instruments, not only Bitcoin. Few of my fiat bank apps are the same - sending money with one click. And while there could be a chance to get that fiat money back, I can assure you it won't be easy.
I am not sure how people make such kind of mistakes, whenever I try to make transaction worth of any amount will follow some process.
First one is checking the destination address manually after pasting them on the sender address so I can avoid sending my Bitcoins to wrong address.
Then fee is another important aspect I lookout for, the best and cheapest I will choose after analyzing the Mempool it hardly take a minute or two find the right one which followed by enabling RBF function.
People who follows the same thing as me can avoid their life savings.

If the user try to get their BTC back & BTC.com don't give back, they will never be supported by community for sure.
Well, it depends. If BTC.com have already distributed that $82,000 to miners, then it is no longer theirs to give back. They almost certainly have enough profits that they could refund the user in question, but it would be a gesture of good will as opposed to being required by the community. There is no requirement for mining pools to be a safety net for user mistakes.at least ELECTRUM WALLET does that
It is highly unlikely that this transaction came from Electrum, or any other mainstream wallet. Every wallet in anything even close to mainstream use knows how to handle change - if it didn't, people would lose money constantly and such a wallet would immediately be abandoned by everyone. Further, no fee slider is automatic algorithm is going to let you go as high as selecting almost 2 million sats/vbyte as a fee for the same reason. As I said in my above comment, this transaction was almost certainly someone trying to craft a transaction manually, sending 5000 sats as a "test", and forgetting to send the rest of his UTXO to a change address. It's a lesson to stick to tried and tested wallets unless you really know what you are doing, and even then, make sure you practice on testnet first before you do something stupid and lose 3.5 BTC in fees.
Usually this happens when someone tries to create a transaction manually or is programming some new piece of software. They set up a small "test" transaction of a few thousands sats, forgetting that you must specify a destination for the full amount of bitcoin you are spending, and the fee is simply calculated by whatever fraction is left that you have not assigned a destination to. Since they only assigned a destination for 5000 sats, the remaining 3.49 BTC was used as a fee, working out to 1.8 million sats/vbyte.
BTC.com mined the block, so the user in question should contact them, explain the situation, sign a message from the input address, and ask for the majority of the funds to be returned. Other mining pools have done this in the past when such obvious mistakes have been made.
The problem doesn't seem to be a matter of pressing the send button because, your often asked if your sure and notified by the wallet, at least ELECTRUM WALLET does that, it notified you that the amount as fee is unnecessary too high and you could either decline or proceed at that point. So, it's more about the calculations and you've really got to know about what your doing.BTC.com mined the block, so the user in question should contact them, explain the situation, sign a message from the input address, and ask for the majority of the funds to be returned.

My first transaction, I paid a relatively high fee without knowing and it hit me only when the transaction was all done. Have the pay rate in sats per byte was my confusion, I never really understood. So, it's about the learning the math's behind.
And here it is, another use of a signed message. Reasons to suggest why OgNasty's 'Newbies can you sign a message' is important.
I'm not sure they will return rewards unless the pool will show good will and assume all costs to cover the mistake made by sender.
If it was a mistake and the owner of the address can prove with signing a message from that address, since the blocked was mined by BTC.com, I'm sure they will come forward and return the BTC. I guess there was a few similar cases we have see. If the user try to get their BTC back & BTC.com don't give back, they will never be supported by community for sure. 
A similar incident happened to an eth user who accidently sent more than $300k in fees. The good think is that the mining pool which solved the block "SparkPool" agreed to send him back half of the amount.

o_e_l_e_o is right. The only thing that can be done right now is to contact the mining pool (btc.com) and proove ownership of the sending address then try to reach a compromise with them.

I have not been observant with my transactions fee when am sending Bitcoin but for when I had a trouble with my transaction, made a transaction that lasted days before reaching where I sent it, I think it's not that they don't check, they check the price, the address but they don't think that they should not omis transaction fee and like those in my category that have complications in editing it.
Can you share some?
Sure.This user paid a fee of 2.5 BTC by mistake in 2017. Antpool mined the block, and then returned the fee to the user after he appealed to them for help on this forum: https://bitcointalksearch.org/topic/m.18122537
Here's another one back in 2013, where ASICMiner refunded a fee of 200 BTC: https://www.reddit.com/r/Bitcoin/comments/1lb5my/asicminer_refunds_the_accidental_200_btc/
It's also happened on other coins as well. Here, Sparkpool returned 1,050 ETH: https://www.btcnn.com/mining-pool-receives-139000-as-reward-for-returning-accidentally-sent-ethereum/
Indeed, BTC.com have offered to refund an accidental 80 BTC fee in the past. I'm not sure if it was ever claimed, though, but it bodes well for the user in this case if they want to try to claim back their mistaken fee: https://medium.com/@akohut/accidentally-pay-an-80btc-transaction-fee-please-contact-us-for-a-refund-1931b08a2623
This can't be the mistake of what you mentioned or the usual mistake we are thinking of. None of the client would suggest such higher fee, no one would use such high fee per byte of course unless they want to gift the sum to the miners. Possible because there are a lot of people who own million worth of crypto, I will not be surprised if it was a gift to the miner.
Other mining pools have done this in the past when such obvious mistakes have been made.
Can you share some? I'm working on an article long ago regarding this. Would be happy to have some. I think his transaction was manually constructed and he mixed addresses for receiver and change.
The transaction does not have any change. Just one input of 3.49 BTC and one output of 5000 sats.Usually this happens when someone tries to create a transaction manually or is programming some new piece of software.

Mistakes such as this one aren't uncommon in the network, even users who trade via p2p need to make sure transactions has more than three confirmations before sending their trading partner cash or whatever is part of the deal/transaction, all this are necessary precautions to be carried out if you're a Bitcoin user; always double/triple check addresses before sending, cause any mistake made will be on you, the network is decentralized, so if you lose your funds, they are more or less lost forever, so the responsibility rests on you.
"Think twice before finalizing transaction by pressing send"
This is always important and it's not only the amounts have to be checked, but also the addresses.
Also if one is not familiar/comfortable with certain wallet he's using, better seek for wallets that support Testnet and play with it for a little time until he understands what he's doing. Then go on and use that wallet.
(Nowadays also spending some time on mempool and fees related websites can also be of great help for newbies).
WOW 
this is so unfortunate for him!!
I feel sorry for that guy, but it is old news, unfortunately, as from time to time this very mistake repeats over and over again.
I always check the mempool and transaction fees, and decide correspondingly, is such a newbie mistake!! and we keep seeing people with big money in Bitcoin who still fall in these uninformed behavior.
