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.



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.

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:

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.

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.

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.

See this:


https://help.coinbase.com/en/coinbase/managing-my-account/other/the-multisig-vault

Coinbase 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.

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.


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.

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.


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.

There was a discussion about that among bitcoin developers and they decided to do so.
For more information, read the topic created by theymos. Forum moved to bitcointalk.org

I just made a search and I think low value topics was what caused developers to make such decision.
Visit this thread: Why is this forum considered terrible by our development overlords?

Before bitcointalk.org creation, the forum was hosted on forum.bitcoin.org

Read the old post made by theymos, for more information.

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

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 (public key of) address received 50 BTC in 2009, spent 19.01 BTC of that and received 30.99 BTC as change.


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.

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

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.

I hope I have understood you correctly.

As already mentioned above, the user in question has never earned any merit.


What 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.

This doesn't make your wallet a cold wallet.
With just disconnecting your computer from internet when generating the wallet and uninstalling the wallet, you don't really increase your security. If you want to have a cold storage, you should create your wallet on a computer which has been always offline and will be never online.

If by recovery seed, you mean a seed phrase which usually includes 12 or 24 words, take note that there is no seed phrase in Armory. In Armory, private keys are backed up by root key.
Armory's root key includes 18 meaningless words and that's different from a seed phrase.

For generating a new address, you can use each of offline and online wallets.


The unsigned transaction must be created using the online wallet.
Take note that for creating the unsigned transaction, your wallet needs to know what UTXOs you own. The offline wallet has no information about your UTXOs.  

Prediction 2: $34,512.22
