So, your wallet is not synced.

I am not sure I am understanding you correctly. Are you saying you are not connected to the internet?

You need internet connection, so that you can get your transaction history from a server.
If you are using electrum as a cold storage, the wallet which contains your secrets should be on a device which is disconcerted from the internet, but your watch-only wallet should be created on an online device.  

This is right, but OP shouldn't do that.

The value of the coin OP received in the unconfirmed transaction is too low and it's not enough for covering the fee. Therefore, the fee required to be paid for the child transaction will be bigger than the value of that coin and OP would waste money on transaction fee.

Also, with adding another coin to be used as input of the transaction, OP would increase the transaction size and transaction fee.
Of course, this would act as consolidation of outputs, but it's not a good time for that as the network is so congested now.

Is your electrum wallet synced?

If you are using the desktop version of electrum, check the circle located at bottom right corner of the window and if you are using the mobile version, check the circle located at top right corner of the window.
If the circle is not green, you are not connected to any server.

If the circle is green and the wallet is synced, check if you made the withdrawal to the correct address.
If you are using the desktop version, go to "Addresses" tab and if you are using the mobile version, tap on your wallet name at top of the screen and then "Addresses".

In the case you don't see "Addresses" tab on the desktop version, click on "View" at top of the window and check "Addresses".

As I already said, the value of the coin you have received is too low and it's not worth to use CPFP at all.
Do you really want to do CPFP and pay fee for a transaction in which you receive only 546 satoshi? Do you know that it's worth less than $0.2?

If you insist on doing so, you should make the CPFP transaction manually.  This means that you should spend the fund you have received in the unconfirmed transaction (along with another UTXO to cover the fee) in a new transaction with high fee.

I just edited my previous post, as I noticed I made a mistake.

There are nearly 2²⁵⁶ valid private keys and 2¹⁶⁰ addresses. (There are more addresses, if we consider different types of addresses).
Therefore, any address can be generated by around 2⁹⁶ private keys on average.

Note that in practice, it's impossible that you can have mutliple private keys that generate the same address. 2²⁵⁶ is a very big number and you can't find the collisions.


No, HD wallet means Hierarchical Deterministic wallet.

Any public key and Any address can be generated by 2^96 private keys on average.


To receive fund, you need to have a bitcoin address and give it to anyone who wants to send you bitcoin.
You need the private key associated with your address for unlocking the fund you receive.

A private key generates a public key and the public key generates your address.
Usually, you don't need to know your public key at all.

Instead of having a single private key and a single address, you can use a HD wallet and generate a seed phrase.
A Seed phrase is a series of words. It usually contains 12 or 24 words and it's also called a recovery phrase or mnemonic phrase.
With using a HD wallet, you can have numerous addresses all generated from a single seed phrase.

It shouldn't be difficult to know whether you are the sender or the receiver. If the transaction is adding to your balance, you are the receiver and if it's deceasing your balance you are the sender.

If you are the sender and your transaction has been flagged as RBF, you can bump the fee.
If you are the receiver, you can use CPFP.

If the size of your unconfirmed transaction is less than 500 bytes, its fee rate is at least 10 sat/byte and it doesn't have any unconfirmed parent, you can submit your transaction to ViaBTC free accelerator. If you do so, your transaction will be included in the next block mined by them. They have around 10% of the total hash rate and it's estimated that they mine 1 block in every 100 minutes.


Can you share the transaction IDs? (Note that with doing so, you may harm your privacy. So, don't do that, if you worry about your privacy)

Since you are doing CPFP and not RBF, I assume you are the receiver of an unconfirmed transaction. Am I right?

In CPFP method, you spend the fund you received in the unconfirmed transaction in a new transaction with high fee, so miners include both transactions (the unconfirmed parent and the child) in the same block.

The problem is now the value of unconfirmed output you are trying to spend is too low and that's not enough for paying the transaction fee.


You can send new fund to your wallet and use that for CPFP, but it seems that the value of the fund you have received is too low and it's not worth to do CPFP.

It may worth mentioning that in addition to the maximum size of 500 bytes and the minimum fee rate of 10 sat/byte, there's another requirement that must be met, so that you can use their free service.
They don't accelerate a transaction freely, if it has unconfirmed parent.

Metamask is not a bitcoin wallet. So, that's not Metamask.

Exchanges usually move the fund to their hot wallet from user's deposit address after someone makes a deposit. Since the fund has not been moved yet, I don't think the address belongs to an exchange.
It's more likely that the address belongs to the scammer's personal wallet and he/she has full control over that.

As I said in my previous post, the transaction fee doesn't depend on the value of tokens you send.
If you are going to make a transaction sending only $5 worth of tokens, you are right as the transaction fee would be more than 40% of the value of the tokens you are going to send.

I have used ViaBTC free accelerator many times and I can confirm that it works.


They accept 100 transactions per hour for free acceleration.


I expect OP's transaction to be confirmed soon normally, but there is no harm if he/she submit his/her transaction to ViaBTC free accelerator, as it definitely increases the chance of getting confirmation.

Yes, you can use free ViaBTC free accelerator. Your transaction virtual size is around 140 vbyte and its size must be less than the maximum size of 500 bytes.

If you submit your transaction to ViaBTC accelerator, they will include your transaction in the next block they will mine.
They have around 10% of the total hash power and it's estimated that they mine 1 block in every 100 minutes.

The transaction in question sounds like a withdrawal from a custodial service.
Custodial services usually process multiple withdrawals in a single transaction and that can be why there are 18 receiving addresses.


As I said in my previous post, there is no outgoing transaction made from the address in question and the fund is still there.

If you hold at least 2500 FUN tokens, you should get WOF spin every day.

You can go to "premium" tab and scroll down to see the table displaying number of spins you should receive per day according to number of FUN tokens you hold and the number of days you have held them.

You should see a message saying "You have  x FREE WOF SPINS. Play them here!" on "Free BTC" tab.

The victim's fund was sent to bc1qq0aheutystzzw4vc0kn5fkuvnp54ju3yckpmww. Am I getting you correctly?
If so, there is no outgoing transaction from that that address at all. The address has received 0.08949505 (which is around $3,100 worth of bitcoin, not $7,300) in the transaction in question and 0.20808782 in total, but hasn't spent any fund.

If you want to make a FUN transaction from your wallet, around 50,000 unit of gas is required. Currently, the required gas price is around 25 Gwei and you should pay around 0.00125 ETH. The required fee rate may change over time.
Note that the fee must be paid in ETH and the it doesn't depend on the amount you send.

If you want to make a withdrawal from freebitco, the current fee is 1398 FUN. If you want to make a withdrawal from an exchange, the withdrawal fee varies from exchange to exchange.  
If you want to purchase FUN tokens on freebitco, note that the sell price is around 13.3% lower than the buy price and you lose 13.3% of your money, once you buy FUN tokens.

No. The average time it takes to mine blocks depends on the difficulty and the the total hash power of miners. The number of transactions in the mempool has nothing to do with the block time.
It may worth mentioning that, the average block time is always approximately 10 minutes on average and the difficulty is adjusted every 2016 blocks to keep the average block time close to 10 minutes.

Using mempool.space is so easy.
If you are in hurry, use the fee rate they display for high priority.

Just take note that the fee rate displayed on mempool.space or any other website are just estimations. The required fee rate may increase once you broadcast your transaction and it takes a long time to be confirmed.

I recommend you to avoid trust wallet and use a wallet which supports RBF. In this way, you can increase the fee even after broadcasting the transaction easily.

Using jochen hoenicke's website is also easy.


Take a look at the following image. I just just took it from the website.



Acording to the image:
There are around 200 vMB of transactions paying at least 1 sat/vbyte and waiting for confirmation.
There are around 80 vMB of transactions paying at least 2 sat/vbyte and waiting for confirmation
..
..
..
There are around 1.4 vMB of transaction paying at least 50 sat/vbyte and waiting for confirmation.
There are only 0.78 VMB of transaction paying at least 60 sat/vbyteand waiting for confirmation.


Since miners prioritize transactions based on their fee rate and each block can contain up to 1 vMB of transactions, if I want my transaction to be confirmed fast, I should set the fee rate to at least 60 sat/vbyte.
Note that since more transaction will enter the mempool, there is no guarantee that 60 sat/byte will make my transacton in the ext block and I can set the fee rate to 70 sat/vbyte or even more to increase the chance of getting confirmation in the next block.

If I am not in a hurry, I can set the fee rate 12 sat/vbyte. That will put my transaction around 11.5 vMB from tip and since more and more transactons will enter the mempool, my transaction will take a long time to be confirmed.



CPFP means Child Pays for Parent.

Assume that I have received a transaction with a low fee and it's unconfirmed.
If I spend the unconfirmed output(s) received on that transaction in a new transaction with high fee, I can increase the chance of getting confirmation.

Take note that transaction can't be confirmed as long as they have unconfirmed parent. So, if the child is paying high fee, so that it's enough for both transactions (the unconfirmed parent and the child) to get confirmed, miners  will include both of them in the same block.

If you want to do CPFP, you can spend the fund received in an unconfirmed transaction with a high fee to your own address.


The post was edited to fix a typo. Thanks Pmalek for the correction.

You are right.
The scammer replaced the transaction that had been made to you with a new one and the address which received the fund in the replacement transaction is probably owned by the scammer.

As stated by Bitcoin_Arena, the fund was moved between many other addresses to make tracing the fund difficult.
