Bitcoin Forum

Hi all,

I was expecting a transfer of $1000 in btc.. I saw incoming of $1000 in my wallet, then i also saw $100 incoming from the same sender.

20mins later the $1000 vanished and i had only $100 left.. Can someone confirm what exactly happened? Im confused. I thought once a transfer is sent and you see it on incoming it cant be changed or modified?

Do you care to share the transaction ID with us?

That way we can scan it and check what really transpired.

Right now the only answer you’ll get will just be based on guesses or speculations.

As mentioned above, difficult to say without seeing the TXID.

But if you received two amounts in two different transactions, and then the first 1000$ vanished, it's very possible that whoever sent it, used RBF to resend the funds to himself (assuming that transaction didn't receive any confirmations of course). It could also simply a display issue from your wallet/service you're using, but that's less likely.

It could also be possible that the sender sends two transactions at the same time to two different wallets, and both receivers can see the incoming transaction using any explorer or some wallet that shows all transactions from the same sender to different addresses. When the transaction is confirmed, only the receivers will see the amount assigned to their address.
 
I do see a similar thing using Electrum wallet to view incoming transactions: my assigned amount will be visible on my overall balance, and my address will be marked to separate it from other receivers.

If the transaction of $1000 did not receive at least 1 confirmation, then the sender could simply spend the same amount in another transaction by using the same input with a higher fee than in the first transaction. This is the so-called double-spend in case the wallet has the RBF (replace by fee) option.

Maybe you are not just sincere with the whole story, why can't you post some proofs to back this up?

Also, hope you were not under drugs or alcohol at this time that you saw $1000 and again $100 and one just disappeared. No, it might seem like a joke, but it happens, people would narrate something but will not totally be sincere about the whole story, and you might not be seeing clearly at that time.

My advice for you is to take the issue up with the sender, such is the only one that can shed light on it. Just ask him for the details of the transfer (TXID), by this, everyone would know what happens. Bitcoin transactions are not hidden.

OP at first, it is likely the sender made two transaction at the same time possibly you were to receive something lesser from the sender than you expected or that amount was a wrong input by the sender and maybe they corrected it by using the RBF (replace by fee) option so that your transaction does not scale through that figure and I believe after the other transaction must have been confirmed then the sender likely allowed yours scale through by also using the RBF option if that is the case.

All these are just speculations though but it would be nice you put up the transaction ID so we could see for ourselves and be able to ascertain what really happened otherwise everything you read hear would be a guess work with no proof of action. If you can as well tell us the time of the day it happened then we could also tell what happened.
 

Its impossible to say for sure until you shares more info like txid of those transactions, but from the limited amount of info you shared it looks like it could be a double spend case. Then again, if someone wanted to scam you by doing that, why would he even send you that $100 transaction.

Either way, once you send more info we might figure out what exactly happened there.

This is absolutely a day dreaming scenario. OP should show us the transaction ID to the both transaction  for clarification so we do not start saying things when the situation is an unrealistic one. Most times things f this nature happens and it is backed with proof for members to see and  know what transpired so as to proffer solutions but OP has failed to do so making it looks like it happened real when there is no evidence of such transaction but however, if it is real then I would say the sender used a replace by fee option to thwart your own pay and used the same RBF to resend your pay in a lower amount. That is just it.

If you are not satisfied,with the response to your inquiries, you can upload the transaction hash for the forum members to see  and if you know the sender, you can get in touch with them to know what happened.

You didn't ask yourself why he is sending an extra $100?


An unconfirmed transfer can be changed or modified or not even confirmed at all.
That's why you should wait for 6 block confirmation before taking that money for granted.

What happened is that most likely you got scammed, they sent you $1000 worth of BTC with low fees you released an escrow or paid something or sent your coins and then they simply replaced the unconfirmed transaction and they sent you $100 probably as cover up to claim in a dispute that's the amount you agreed on!

In the past years, all OPs posts have been about unconfirmed transactions. I'm pretty sure he knows by now how Bitcoin confirmations work. This topic doesn't make sense.

I also think that the initial transaction of $1000 has been double spent by the sender, sending it to another wallet since it has not confirmed yet, then another transaction worth $100  were made to confuse you as a receiver that the first transaction should go through since you had received that second transaction of $100.  

I believe the sender scammed you of by double spending the $1000 expected transaction and send you $100 instead.  @OP you can read more explanation about double spending in this article: https://www.investopedia.com/terms/d/doublespending.asp

This should be what transpired. That's if OP was truthful with what they said happened. Otherwise, one would conclude that OP is just trolling since they still haven't presented a simple thing as the TX ID for that transaction to buttress their story.

What I guess is that the first transaction is $1000 with RBF enabled and a low fee since the current mempool right now is a bit congested and a few spikes recently paying 1 sat this TX will be stuck on the mempool and the other $100 transaction can be also a trap.

Would you mind to tell us if the $100 is confirmed better check it directly to the blockchain? But if not then the $100 is another trap same as the first transaction.

What are you dealing with the sender? If he promises that they will give you BTC worth $1000 with a bonus of $100 it's a sign that the sender is a scammer.

Yeah... A few members have already picked up on the fact that you have been asking the same questions since 2017. It is kind of weird that you haven't picked up any knowledge about unconfirmed transactions and double spending in over five years. Are you really being genuine with this question?

To buttress this, the OP has not addressed the issue or provided any proof as advised and it's running to 24 hours now, such can't delay this much if such a pressing issue is true.

Maybe the OP thinks we are playing here, I don't see why such shouldn't be sanctioned for this falsehood.

Please share the transaction hash or explorer link so that we can check what has gone wrong. It's usually not the case.

Another possibility is that the sender of 1000 USD did not 0ay the required network fees that why it wasn't confirmed. But you should see that transactions in the block explorer.

The OP explained exactly the experience of RBF in his own question. no need to beg him to supply TXID as the vanished $1k version is gone(rejected) so no investivation or new info can be gathered

the 20min wait for the $1k to be left unconfirmed shows there was an insufficient fee paid, thus later the $100 appear with a priority fee(higher) and so at the 20th minute the $100 confirms thus completely making the $1k rejected.

in short yes the sender done a RBF scam on the user and the user should demand the remaining $900 from the sender if the receiver required $1k

as for others warning about not to blindly trust zero confirms. this is true for amounts more then the price of a soft drink. pizza of something small. and especially true for the subnetworks that mess around with unconfirmed 'smart contracts' that dont settle when received, but days, weeks months later. as they too have many ways to switch around which tx gets confirmed finally later on

the usual loose guideline of risk tolerance has been (before RBF existed)
zero confirm: <$30 (0.001)
1 confirm:>$30 (0.001+)
2 confirm:>$300 (0.01+)
3 confirm: >$3k (0.1+)
4 confirm: >$30k(1+)
5 confirm: >$300k(10+)
6 confirm: >$3m(100)

some still use this loose guideline but be sure to keep im mind that RBF has made it easier to steal from zero confirm and also from certain subnetworks that have badly developed mechanisms

It's what I thought double spend came to my mind. The OP hasn't shared info so isn't possible to know. If he doesn't want to post TXID he should use blockchain explorer to see why $1000 disappeared. If I'm expecting $1000 but receive $100 I'll ask the sender what happened.

In this kind of case, you have to be very careful from the sender you're dealing with, maybe he has some of the security informations to your wallet, was he the one that helps you while creating the wallet? Don't try to allow him have any clue about your wallet keys in other for him not to take charge of it unaware to you, he may probably sent the two transactions and once they two got confirmed wired back the $1000, so providing the transaction id for that your account will help alot, but know that bitcoin transactions are irreversible and cannot be altered, except if your wallet is compromised, the reason we keep saying that not your keys not your coins but many don't understand why.

This is a very strange story. It just doesn't add up. Probably if you can post proof, maybe it can be investigated.
I am never experienced such, and I don't know of anyone who has experience same, this is novel to me.
Maybe you can reach out to the sender to send you proof of the $1000 transfer.

Could you please share your TXID with us to confirm what happened? It appears that the sender may have canceled the transaction even before it received any confirmations, redirecting it to their own wallet in case the wallet supports replace by fee (RBF).

It could also happened that there might be an issue with your wallet. I'll just wait your response to better understand the situation, cause it's weird to expect that you're receiving 1K$ but getting 100$ instead.

I believe OP might be inadvertently promoting spam here. Either they're being deceptive, or their intended message isn't coming across clearly. This isn't aligned with how Bitcoin operates. To address this, it's important to provide a detailed account of the exact events and circumstances, including transaction details if privacy isn't a concern. Without this information, the threads could become inundated with spam, hindering any potential solutions.

After reading all what the OP said, I came to draw a conclusion that is only possible the OP is seeking for attention by creating such thread that request answers from members here but have failed to provide detailed information on how the possible result required might come to light. I think the OP should just either lock the thread or provide the transaction details (id).

That's the first impression I have when I first read what the OP said and the other user while the OP didn't provide the tx ID as requested by her.
My belief is that the sender sent the transaction to two different wallets while $100 worth of BTC is the transaction sent to the OP but she saw $1000 thinking the sender make a mistake by adding another zero or the $1000 was a change.

That's a little suspicious. First off transactions in the blockchain doesn't work that way so it's not a bait-and-switch. Second what do you mean by expecting? Are you saying that this person who's sending the money gave you a heads up that he's sending 1 grand? Or are you only made aware of it since you saw it incoming? Lastly, could you send us the transaction ID so we can look at it? We gotta make sure that the transaction you got was real and you could only do so through confirming the transaction ID exists and is in line with your stuff.

His message isn't coming across clearly so I viewed his account. He's been a user from 2017 so he should've known about double spend. I'd like to believe he isn't being deceptive but if he doesn't post info about TXID it'll put doubts on him.

You are partially correct. Once a transaction is made on the bitcoin blockchain it can be replaced with another transaction which uses the same input and a higher transaction fee.
The previous transaction should not have received any confirmation on the blockchain for it to be replaced. Once 1-2 confirmations are happened then it becomes near to impossible to replace that transaction.
This is why it is recommended to have at least 2 confirmations for the transaction to consider it done.

Transaction has been sent at $1000 worth of Bitcoin with a low transaction fees, that causes delaying in confirmation and the same time the person make another transaction with the same input with a high gas fee that causes the first transaction delay by short pay $100 worth of Bitcoin.

Can share the Transaction ID and see what really happened, because Bitcoin transaction is transparent.

If this really happened and you are not mistaken, then you need to give more information or provide evidence, otherwise it is very difficult to say something for sure. I hope the sender was familiar to you and you did not lose money, if at all possible
If you share the transaction, then everything will become clear

If it's real, he'll share it.
All transactions can be seen, not even just Bitcoin, transactions on the blockchain are all transparent.

The transaction owned by OP, seems strange, but maybe the sender already has OP's private key and it's just to lure OP to top up to take the $100.

Many wallets are hacked by the drain method so that the scammer has control of the wallet that was drained.
Usually, there will be some special tokens that they send as a trap so that the wallet owner tries to sell it and monetize it on fake Dapps, so that the wallet will be hacked. Be wary of such methods.

If the story of the op is not one of those fabricated story by now the op would have shared the transition ID to back up the claim. It's so funny seeing stories about Bitcoin this way when Bitcoin transactions are clean and clear, the next time the op will come demanding for help here with the topic scam scam scam with no proof as if the forum is a place where all sort of things are said without good reasons or proof, let's go op drop another one 😂.

Whether or not the OP's information may be true, I am intrigued that this could happen, wallets are supposed to have security encryption to such a degree that they do not allow this type of case... And they can tell me that  type of option exists due to the  possibility of making a mistake when making a transaction, but by God, we are talking about bitcoin, not any other current currency, for obvious reasons, before making a deposit to another person, you must make a last revision of the amount that is being made, so I don't see any sense in him that he was wrong and therefore redirected said transaction, so it makes me think that you are right, it is very likely that the OP has fallen for a scam. It is incredible how this type of incident has increased, I suppose that it is because of the popularity of bitcoin that thefts have increased considerably, which is why you have to take the necessary precautions, if before you were susceptible to transfers and exchanges, now there are to double this distrust... because apparently not even wallets are so safe now.

If the Bitcoin transaction had been done months earlier (resulting in your $1,000 becoming $100), I would have claimed that the weak market was to blame. When the market experiences a bull run, it will undoubtedly soar back to $1,000. But in this instance, you recently received bitcoin, which is why you are having confused thoughts.
It will be hard to believe until you provided the requested TXID, to know what lead to the cause of $1k-$100 in a short time

= are you using two more different wallet to receive btc from the sender?

= Did,you modify(change) the address of your wallet few minute before this transaction?
