Title: Bitcoin qt blockchain rebuilding
Post by: mlk on November 22, 2017, 03:02:32 PM
Good evening community,
Some years ago I bought 200€ of bitcoin.
I spent 100 euro in two different transaction.
After this I forget my bitcoin and my wallet.
Some days ago I try to rebuild my bitcoin qt wallet,
Installing new 1.5 version, specifying olds database folder and executing the app from batch:
BitCoin-qt.exe -datadir=d:\BitCoinData

Now, after many days of processing, bircoinqt rebuild block chain, but my wallet is empty....
And there is no trace of my old transaction...

Where I wrong?
Maybe I have used a incorrect database folder?
Thanks for your suggestion and really sorry for my English.
:D

If you are online and the blockchain is fully synchronized, your BTC balance and previous transactions should be visible.
Are you sure you used the right wallet.dat? Or do you have a paper/digital backup of your privatekey/passphrase?

Did you try to start your old wallet before upgrading? If so, what did it show?

The latest version of Bitcoin Core (https://bitcoin.org/en/bitcoin-core/) is version 0.15.1. If you have version 1.5, what exactly did you download?

Are you sure it used your old wallet.dat file? Or could it be it created a new wallet?

Just to be sure: did you make a backup of your wallet (wallet.dat) before upgrading?
