JEON (and Everan426),

What happened to you guys?  I need to buy between 1,000 and 5,000 BTC every single day.  It is so hard to find anyone who can do those large volumes so I was hoping to go through you guys.  But, alas, you have disappeared so I will have to send my business elsewhere.

You could take the same 12 words to the  https://dcpos.github.io/bip39/ web site, type them in, scroll down to the bottom and see 20 Bitcoin addresses.

You can go into your recovered wallet and press the new address button 19 more times.

I would expect the 20 addresses produced at  https://dcpos.github.io/bip39/ to match the 20 addresses in your recovered wallet.

If they do match, that is expected.  If they do not then let us know.

Question:  On the SETTINGS -> Addresses page have you ever pressed the blue "Create New" button?  If not then please do not, that would only confuse things more.  If you have please let us know.

Yes, you can do exactly as he said - but I think you will just duplicate what we have already done.

1) Type your 12 words into this web site:  https://dcpos.github.io/bip39/ in the BIP39 Mnemonic box

2) Once it accepts the 12 words, scroll down to the box that says "BIP32 Extended Key (addresses only)" that is where your xpub is.

Check this xpub.  Since we basically did the same thing when we typed your 12 words back into a new account a blockchain.info I will bet the xpub you get will be the same, it will probably be this one http://imgur.com/a/uMtD2 (xpub6CKq5V...)

If it is the same as the one we got by typing in the 12 words to blockchain.info then, yes we have duplicated that result.  If the same 12 words produce a different xpub then that would be a bug.

The problem is that since the 12 words you get from your blockchain.info account produce xpub6CKq5V... (I think you will find this to be true again) you do not have, or have not found, the 12 words that produce the other xpub  xpub6CVUkj... which is the one you need to produce the bitcoin address 1Masr1mezkmAqhtWT9RsWzt2e21aYApco.  So, you are stuck and you will never find the private key to own those Bitcoins held at the address 1Masr1mezkmAqhtWT9RsWzt2e21aYApco until you get the 12 words or the xpriv/xpub key pair that produced that address.

If you import those 12 words (or the xpriv key produced from them) into any other wallet you will/should get the same result since one set of 12 words maps directly to only one xpriv key which maps directly to only one xpub key which maps directly to an exact sequence of private/public key pairs.

You will be able to see, when you type your 12 words into the site https://dcpos.github.io/bip39/, the sequence of Bitcoin addresses and corresponding private keys produced by those 12 words by scrolling down to Derived Addresses.  It will show you the first 20 but you can get the next 20, and the next 20, and the next 20 for as long as you want to press the next 20 button.

You can verify all of this by checking the first 20 addresses produced at https://dcpos.github.io/bip39/ with the newest wallet you created at blockchain.info with your same 20 words.  Just press the new address button in your latest wallet 20 times.  It will create the same 20 Bitcoin addresses.

Thanks for trying to help.  Did you read the thread?  We have been through a lot already on this issue.

That is exactly what I originally thought but I have been very careful in trying to rule out that possibility.  Yes, this is the most likely explanation.  Andlog972 when you get a chance please think this possibility through and make sure that is not what happened.

I sent an invite to the thread, we will see if we get a response to my invite.

Yes, it can be changed:  SETTINGS -> Security -> Wallet Password -> Change

DO NOT UNDER ANY CIRCUMSTANCES GIVE ME ANY PRIVATE KEY INFORMATION, EVER.

I do not want it.  Do not send me any private keys or xpriv keys.

Thanks.

You should be able to list all your past, current and future private keys since the new wallet is a deterministic wallet.

You should be able to export your seed words at SETTINGS -> Security -> Backup Phrase

Then, using the wallet recovery phrase (12 words) you get go to bip32.org or some other deterministic wallet, I have used Wallet32 in the past, and generate your xpriv key

Then, from your xpriv key you can generate your entire private key sequence, transaction history, etc.

Note, I have not tried this but it should be possible.

So, now you may have something to go to blockchain.info with, maybe.  It appears that the same seed created two different xpub keys.  That would be a bug since one seed should created one and only one xpriv key which in turn should create only one xpub key.

Why not send them an email and point them to this thread and see if they can take a look at it.

Now we are getting somewhere.  Maybe.

The xpub key shown in this image:  http://imgur.com/a/uMtD2 (xpub6CKq5V...)

Is not the same as the xpub key you gave us to work with:

https://blockchain.info/xpub/xpub6CVUkjcP4PUsU99V2nTpxXrjcvnjqfLkg94YnGXUW5iDBAnwPTZPK9yqjqTzprf47zC8gbvWvEo8JomPnq22S7ABgjVPCPmCWnXbpUxx44h

We need to explain that difference to explain what is happening.

Explain exactly how you got the xpub key in the image that starts with xpub6CKq5V.

And try to reproduce getting the xpub key that starts with xpub6CVUkj and tell us exactly how you do it (it should be the xpub from your original wallet, if I have not lost track).

If during your investigations you find another xpub key that is different from the other two above, then make a note of that also.

Tell us what you find.

Pairing is not the issue since you never mentioned pairing your account to a device.  Did you ever pair the wallet to a device?  Creating it on a different device should not be an issue but you might try accessing the wallet from the device you used to create the wallet.  That might tell us something.

And, also try recovering the wallet from the seed as I described above.

First get your seed information:

1) SETTINGS -> Security -> Backup Phrase
2) Print the recovery sheet
3) Press Next Step
4) Write down the first four words on the sheet
5) Write down the second set of four words
6) Write down the last set of four words
7) Verify four of the words you just wrote down by typing them back in

Now try to recover your wallet using the words you just wrote down by opening a new browser and going to:

https://blockchain.info/wallet/recover

Let us know what happens.

I am just about out of ideas.  Just to make sure:  If you start on this page:  http://imgur.com/2jgQxLG and click "Show xpub" you get the xpub you sent us.  Right?

About the last thing I can think of is to have you export your seed information and try to recover it in a brand new totally new wallet.

Does anyone have any better ideas?

I don't think a screenshot of the send screen will help much but go ahead and do that.

Then, from this screen:  http://imgur.com/ICJ3ez5

Press the "<- Back" link right above the text "Your Blockchain Wallet contains" once and take a screen shot and post it

You are assuming that core will get the default predominate wallet in 20-50 years when this is an actual issue?  Really...

Do you honestly think that Theymos can implement coin blacklisting by himself?

Implementing a workable coin blacklisting scheme would take consensus.  Big word, look it up.

Good news for Homeland Security and the Justice Department!  Today the BTC they took from me are now worth $84,845.22 so they have doubled their money!  Their investment strategy (take and hold) is working for them.

Thanks Bruno.

In addition to this address, which appears to be their main Bitcoin address:

https://blockchain.info/address/1HD2x5dH6SrMnvFRrWsTZ6ZSwtafeNRL26

Here is a list of other addresses they may have used:

https://www.walletexplorer.com/wallet/45d98a5dc51021bb/addresses

From this we can see they used the following services:

CoinPayments.net
SatoshiMines.com
MtGoxAndOthers
FaucetBOX.com
BitPay.com
C-Cex.com
MoonBit.co.in
BitPay.com-old
Coin-Swap.net
Bittrex.com
Poloniex.com

FWIW:  I am pretty sure they are using an old blockchain.info account.

No transactions.

Question:  even though you just used this wallet recently when was the wallet created?  Was it created a long time ago and then just recently used for the first time?

Yes, a screenshot showing the address 1Masr1mezkmAqhtWT9RsWzt2e21aYApco in your wallet would be a fantastic idea.
