Title: Import wallet.dat from 2011
Post by: _asdf_ on December 11, 2017, 04:40:18 PM
Hi guys,

I mined some BTC in 2011.
Then I did nothing withem beside doing a backup of wallet.dat and uninstall the bitcoin client.

Now after years i reinstalled bitcoin core client, download the whole keychain and replace the wallet.dat (2017) with my backed up one (2011).
When I start the client i get an error: "Ein schwerer Fehler ist aufgetreten. Bitcoin kann nicht stabil weiter ausgeführt werden und wird beendet"

Then I run the bitcoin core client again with -reindex -research parameter...it took a while...and then I get displayes there are no BTC in the walltet but also no transactions.
After run it without -reindex -research I get the error again :(

I tried a reinstall of the client but nothing changed.

Do you know any help?


Is it save to upload the wallet to blockchain.info?
If i upload it to blockchain.info the he hoster of the webseite have access to my wallet, haven't he?

Try to dump your private keys by following these steps:

1. Start Bitcoin Core
2. Stop Bitcoin Core
3. Datadir should be created, open the datadir folder (https://en.bitcoin.it/wiki/Data_directory)
4. Replace the existing wallet.dat (backup it if you already had Bitcoin Core installed) with your old wallet
5. Start Bitcoin Core
6. If you want to export your keys, open the debug console and type dumpwallet <filename>

With your private keys, download the Electrum wallet[1] and when prompted to create your wallet, choose: "Import Bitcoin addresses or private keys" -> Paste your list of private keys and click Next.

Then, just see if you can see your balance and spend your coins.

I'm sure you are aware, but this is a scam.

I'm sorry that I cannot offer any assistance to your original problem.  I truly hope you can recover the BTC.
