Sorry for the spam, im just really worried because 100 euro's is not nothing for me. Apologies.
They are not lost, calm down.
I will download electrum now and try to copy wallet.dat
You cant just copy the wallet.dat into any other software.
I did not exported the private key yet. I used the commant and typed my password but what do you need to do next?
It says this:
walletpassphrase "passphrase" timeout
Stores the wallet decryption key in memory for 'timeout' seconds.
This is needed prior to performing transactions related to private keys such as sending bitcoins
Arguments:
1. "passphrase" (string, required) The wallet passphrase
2. timeout (numeric, required) The time to keep the decryption key in seconds.
Note:
Issuing the walletpassphrase command while the wallet is already unlocked will set a new unlock
time that overrides the old one.
Examples:
unlock the wallet for 60 seconds
> bitcoin-cli walletpassphrase "my pass phrase" 60
It means you are doing it wrong. I will make an example. Lets assume your password is "passw0rd" and your bitcoin address is "1LKwwbZZ3XtTznqTKZVnDgj8M59r2QACnv".
Open core, goto the console[1] and enter:
walletpassphrase passw0rd 120quickly followed by:
dumpprivkey 1LKwwbZZ3XtTznqTKZVnDgj8M59r2QACnvit will show something like this "5JC3aq4x63vzX4MMt1CKTymUeadZqFtoWAy9YyyzLrLiDv7CyAQ" -
do not share this with anyone. (this key is just one I created for this example and is not used otherwise)
Now to import that key into electrum, do:
File -> New/Restore -> (select a name, e.g. temp wallet it does not really matter) -> select "Restore a wallet or import keys" and "Standard wallet" and confirm with next -> enter the private key like this:
and confirm with next.
Set a new password, wait a little bit til its synced (green light lower right). You should now be able to see a balance. If not let us know.
