Bitcoin Forum

Hi guys,

https://bitcointalk.org/index.php?topic=782.0 (https://bitcointalk.org/index.php?topic=782.0)

I am looking for this topic owner.  I had the same problem, and I saved the lost bitcoins. I can help this friend. If anyone knows, he can contact me.

He has not been around since 2010 and I checked his post history. No email addresses or personal information have been posted by him asides from a few bitcoin addresses. Try to send him a PM. If he still uses the email address that he registered his account with he will get an email that he has received a PM on the forum. If nobody here knows his personally that might be your best shot.

I don't think your recent experience has anything in common with this 2010 wallet. That sounds like the common problem where the change address isn't in the backup

The starter of the thread was last online 9 years ago of which  he stopped even following the thread he had started after loosing hope. How are you really going to get to him or track him down?  ;D

The 9000 BTC have never left the address to this date  :o

 Hi teknonix I had a situation similar as I lost about 2 to 5,000 btc but I still have my wallet file. Is there anyway you can help me get my bitcoin back. I can give you tip . Please say.

"Just asking for a friend" ;D

On a more serious note, if more than USD 70MM worth of cryptocurrency just lying around the blockchain unguarded isn't proof of Bitcoin's security model than I don't know what is.



To you and any other newcomer reading this:

Do not share your wallet file with strangers. That's how you get your coins stolen.

@OP: If you have found a way to retrieve lost coins that may be helpful to others, please post it publicly so that other users can be helped as well.

Another tip for newcomer:

Do not accept wallet files from stranger which claim to have 'lost bitcoin' in there.
There might be some vulnerability for code execution etc. in core, which would lose to your system getting compromised.

Or.. it simply is malware.

Hi Btcspot,
If your problem is related to change addresses, I can help you. I am able to recover the lost change addresses in the core wallet.

In fact there is no need to back up the wallet.dat after each transaction. If the change addresses are missing, there is a way to solve it.

I can't send a private message. newbie does not accept. I'd appreciate it if you'd send him a message.

1) Nobody claimed that you need to do that.
2) There's no way to solve it if your backup does not have the new keypool. Many things could have gone wrong with the old OP. I don't see why you would care now? Seems suspicious.

I find this very hard to believe. Proof?

 Hi please give me your email so we can talk alright?

Wow, only 4 people (with 2 DT of them) claiming this newbie is a scammer.

Guys, better trust him everything you have.

Today it is easy to get the change addresses and every other address from your backup, but and it is a big BUT...

...In the old days wallets weren't deterministic. Meaning, it was impossible to derive the next keys from your wallet backup.
When the core needed more addresses, it generated them randomly (not deterministically like now) and if you lose those randomly generated addresses there is no way to generate the same keys again later.

Actually the 8999BTC, that you mentioned, are the reason that inspired the development of deterministic wallets that we use now.  So that the same wouldn't happen to anyone ever again.

PS. The 8999 coins will forever stay in the address 167ZWTT8n6s4ya8cGjqNNQjDwDGY31vmHg

I know a lot of people won't believe me. There's a way to prove it.

1. Back up a wallet.dat for a newly installed core wallet.
2. Then open the wallet, make a few transactions with very low amounts. (Do this to addresses in the same wallet)
3. Wallet.dat, which has no change addresses in it and the first backup, will not include these transactions.
4. Now send me the wallet.dat file with no change addresses.

I take out all the transactions and exchange addresses and give them to you.
How do you think this is?


My email: teknonix@my.com

Don't do this.

There's a better way to prove it: Don't send anything to random newbies. I've tagged your account.

You better listen up buddy.


Thats good for the OP didnt explain in details the problem he's really battling with it and all he does is provided a thread of a couple of years back which we both know that the situation of crypto currency is different to those days. Besides, I believe there chance that he posted this thread in the first place to get people like Btcspot.

Beware on this user is an old user who promotes HYIP before it seems that some of his posts are deleted or he manually deleted them. So this is an obvious scam attempt.

Look at this old post https://bitcointalk.org/index.php?topic=1558712.msg15824256#msg15824256

He is promoting an HYIP site and someone scammed of almost 1.6+ BTC.
