I guess you did not check what happened then. The hacker hacked 3.73 Bitcoin and received it in one address.
You are referring to this transaction. Right? OP said that the fund was sent to an address which belongs to the same master public key. That means that the receiving address belongs to the same wallet. The hacker tried to split all the amount into different addresses, so it became tough to trace the Bitcoin.
You are right that the person who made those transactions tried to make tracing the fund difficult, but I still doubt OP's wallet was hacked. If OP lost bitcoin, that could be due to using a fake coldcard that gives pre-generated keys. There are other possibilities as well, but I don't think the wallet was hacked and of course I can be wrong. |

Indeed, you misunderstood his entire text and did not notice others' comments. I assume his wallet was hacked about three months ago, and more than 3.73 Bitcoins were stolen from his wallet by a hacker.
I don't think the wallet was hacked. I think OP doesn't own that wallet at all and is only watching someone else wallet. The 3.73 BTC was sent in this transaction. The transaction contains 2 outputs. The address which received 3.23 BTC seems to be the change address. OP also said that it belongs to the same master public key. If the wallet was owned by OP and it had been hacked, the hacker would move the entire balance in a single transaction. |

I am not sure I am understating you correctly.
You created a multi-signature wallet using electrum in 2021 with 3 co-signers.
You are saying 2 out of the 3 seed phrases used for creating the multi-signature wallet was 2FA seeds. Am I getting you correctly?
If so, that's not possible at all. Electrum 2FA wallet itself is 2 of 3 multi-signature wallet and you can't use its seed phrase as a cosigner seed when creating a multi-signature wallet.
Can you please elaborate more on how you created your wallet? How did you generate your keys?

I don't now if there is a website where you can see how empty or full mempool is but you can view a good statistics on Blockchair.com.
We have Jochen-hoenicke website for checking the mempool state. The tool was suggested above your reply. When transaction fee is 1 satoshi/byte, it's a clear indicator that mempool is really empty. When fee is 20 satoshi or 100-200 satoshi, this indicates that mempool is full.
This is not accurate. Currently, you can get fast confirmation with the fee rate of only 2-3 sat/vbyte, but the mempool of any node with default setting is full and that's why they purge any transaction with the fee rate of less than 1.36 sat/vbyte.  mempool.space |

Also the second receiving address is part of the x pub key so the wallet did it
If that's the case, that address should be the change address. I think the wallet is owned by someone else and all you have is a master public key. If you were the owner of the wallet and the wallet had been hacked, the hacker would steal all the fund. You can not create a new receiving address with watch only wallet because no private key there.
If your watch-only wallet has been generated using a maser public key and not a single address, you can generate as many addresses as you want. |

Please check the video I provided above that is how I withdraw funds out from the vault.
That's coinbase vault, not coinbase multisig vault. Coinbase vault (which is used by you) is a custodial service and coinbase has full control over the fund. There is no real co-signer in coinbase vault. When you approve the withdrawal through your email address, you only tell coinbase that the withdrawal request has been made by the real owner and it's not that you are the co-singer. Coinbase multi-sig vault (which is no longer supported and we are talking about that in this thread) was a 2 of 3 multi-signature wallet in which the user had access to two of the keys and had full control over the fund. From Coinbase help: Note that the multisig vault is different from the regular Coinbase vault, where we handle security on your behalf so you don't have to. If you don't want to maintain your own private keys, you can use the regular vault |

@OP I don't think it would ask for a password because mine only asks for a 2FA code when withdrawing after entering the 2FA it will ask if you gonna approve the transaction or not and then the 2nd email will receive a link to approve the transaction.
Are you saying you have fund in coinbase multi-sig vault and you are able to withdraw your fund from that just with entering the 2FA code and email verification? How is that possible? As already said, they no longer supports multi-sig vault. I feel you are confusing coinbase mutli-signature wallet with their custodial wallet. |

- An encrypted key which is owned by both coinbase and the user. Which I supposed they can decrypt? Can't they? What is the point of an encrypted key in the first place if the user cannot decrypt it? Right. OP has the encryption password and he/she should be able to decrypt the shared key, but the question is how the key should be decrypted, what's the encryption algorithm and what tool should be used for that. Also, I am not even sure if the user share OP is talking about is a master private key or a seed phrase. |

To spend them, install Electrum on an air-gapped device and re-create the same wallet but use xpriv.
OP has now two of the keys, but the the problem is that the one that is shared with coinbase is encrypted and there is no way to import that to electrum. In coinbase multi-sig wallet, there are 3 keys and they are as follows. - An unencrypted key which is owned by the user and coinbase has no access to that. - An unencrypted key which is owned by coinbase and the user has no access to that. - An encrypted key which is owned by both coinbase and the user. |

The guide provided by Abdussamad in that thread won't help OP. OP should recover a 2 of 3 multi-signature wallet. That thread is about recovering a 2 of 2 multi-signature wallet and is not related to OP's issue.
The weird thing is there is no announcement from Coinbase that they are going to terminate Vault Wallet and honestly creating a Vault Wallet does not generate a private key it requires only 2FA and another email as co-signer.
See this:  https://help.coinbase.com/en/coinbase/managing-my-account/other/the-multisig-vaultCoinbase multisig vault is 2 of 3 multi-signature wallet. One of the keys is owned only by the user. One of them is stored by coinbase and the user has no access to that. One of the keys (which is encrypted) is owned by both coinbase and user. If you own two of the keys, you must be able to spend your fund without relying on Coinbase and without any need to 2FA or email verification. |

Thanks for the correction, i tried to find the archive page of the forum but no avail, even in the bitcoin.org or in sourceforge.net.
You can see many captures taken from forum.bitcoin.org on wayback machine. Click here. It seems that the forum was like the current version when it was hosted on forum.bitcoin.org. This [1] is the only the oldest archive recorded of bitcoin.org but not included the first forum look.
The forum was hosted on forum.bitcoin.org and that's what you should have searched for. Bitcoin.org still exists, but the forum was moved from forum.bitcoin.org to bitcointalk.org. |

- I have calculated 1/10 for next level and rounded it in the same way.
This is where the problem comes from. You should calculate the exact prize and then round the result to 8 decimal places. If bitcoin price is 449,999 dollars, the base prize would be 0.002/499,999 = 0.000000004 sat and that's rounded to 0 sat. - Acording to present rules, it is 2 and, of course, they can be changed.
No, As I said above, you are doing the calculation incorrectly. id5000, I don't really understand why you delete your posts.
According to ninjastic.space, you have made 82 posts in this thread and you have deleted all of them. Most probably, you are going to delete the post I just quoted as well.
With deleting your posts, you make anyone who wants to follow the discussion confused. |

Before bitcointalk.org creation, the forum was hosted on forum.bitcoin.org Read the old post made by theymos, for more information. The forum was originally located at bitcoin.org/smf, then forum.bitcoin.org (hence the redirect), and finally bitcointalk.org.
It was mentioned on the thread you link it is sourceforge.net[1], although it's not a domain, it's like you can create a forum using the sourceforge.net website, which is the very first bitcoin forum.
As stated by Satoshi in that topic, the sourceforge.net domain was used before creation of the new forum. Note that Satoshi made that topic on November 22, 2009 and bitcointalk.org didn't exist on that date. Satoshi created the forum on forum.bitcoin.org and that's now hosted on bitcointalk.org |

Thanks, to better understand, "if" I own the private key associated with this address, then:
My balance is 30.99099822 BTC.
If you own the private key of that address, you own 30.99 BTC, but you have to use another tool for spending that. Electrum will display only 0.00099822 Edit: It's possible to sweep the private key in electrum. Read nc50lc's reply. - the 30 BTC from the P2PK transaction made in 2009.
The (public key of) address received 50 BTC in 2009, spent 19.01 BTC of that and received 30.99 BTC as change. - The 0.99 BTC that Electrum recognizes as confirmed for that address
0.00099822 BTC. That's the total amount the address received through P2PKH transactions. |
|
|
|
|
If you check the transaction history of the address, you will see that it has received 50 BTC in 2009.
That transaction is not recognized by electrum, because that's a P2PK transaction and the 50 BTC hasn't been paid to that address at all. That transaction has been made to the public key which generates that address.
Many block explorers display the fund that has been sent to a public key for the address derived from that, but electrum doesn't do that.

@hosseinimr93, Can you verify whether I'm right or wrong? You are good in this type of calculations.
You are right. To be more accurate, the base prize should decrease to 1 sat once bitcoin price reaches $133,333.33. Below are the base prize for different bitcoin prices. | _____________________ | _________________________ | Base prize (in sat) | Bitcoin price (in dollars) | | _____________________ | _________________________ | 10 | 19,047.62 - 21,052.63 | 9 | 21,052.64 - 23,529.41 | 8 | 23,529.42 - 26,666.66 | 7 | 26,666.67 - 30,769.23 | 6 | 30,769.24 - 36,363.63 | 5 | 36,363.64 - 44,444.44 |
4 | 44,444.45 - 57,142.85 | 3 | 57,142.86 - 79,999.99 | 2 | 80,000.00 - 133,333.33 | 1 | 133,333.34 - 400,000.00 | | _____________________ | _________________________ |

So, I tried to restore the wallet file from the drive, but it's gone. It's nothing there.
What do you mean by it's gone? Do you see any outgoing transaction? If that's the case and you didn't make the outgoing transaction, it means that you used a fake version of electrum or your device was compromised. It's also possible that someone had access to your seed phrase. An electrum's seed phrase provides 132 bits of entropy and as mentioned above by satscraper, that's secure enough. |

Use mempool.space. It shows the median and the minimum and maximum fee rate used in a block. Below is the data displayed by mempool.space for the most recent block.  mempool.space
I hope I have understood you correctly. |

As already mentioned above, the user in question has never earned any merit. just randomly i was reading a thread where i seen his profile to capture and post hereWhat you said in that post is wrong. The user is not a legendary member, because of low activity. The user has enough merit for being a legendary member and he will be still a hero member even he receives 1 more merit. The user was a legendary member when the merit system was launched and received 1000 airdropped merit. It seems that he/she deleted some posts and lose the activity and rank. |
