That's the private key,
edit your post and remove most of the characters immediately!All you need to display is the first or first three characters, it will be stolen even if the last 10 characters are crossed-out.
What seems to be the problem is the address that was derived from the key doesn't have any balance (
inputs).
This could mean that the format of your Electrum wallet and BitcoinCore's are different.
When sweeping:
If Core's address starts with "
1" type:
p2pkh: before (
prefix) the private key.
If "
3" use:
p2wpkh-p2sh: ;
if "bc1": p2wpkh:
Also, you might wanna check on an
online blockexplorer if the "
recieving wallet address" that you've specified has a balance.
To clarify to the OP: in Electrum, when sweeping the private key, you must use those prefixes depending on the type of address you got on Bitcoin Core.
If Core's address starts with "1" type:
p2pkh:PRIVATEKEYHERE as the private key when importing.
If it starts with "3" type:
p2wpkh-p2sh:PRIVATEKEYHERE as the private key when importing.
If it starts with "bc1" type:
p2wpkh:PRIVATEKEYHERE as the private key when importing.
It's obviosly the same the last poster said, but it's extremely important you do this as fast as possible, that's why I tried to explain it with other words.
However PLEASE, as nc50lc said, edit your post NOW to avoid getting your coins stolen. Google provably already cached this page, so it's just a matter of time that address is compromised and the funds it has now and in the future are lost.
