<p>That's what your <code>wallet.dat</code> contained. You cannot get that back if you've lost your <code>wallet.dat</code>. Otherwise, Bitcoin would be worth $0 as anyone could just &quot;make up&quot; private keys with any amount of Bitcoin.</p>

I meant "Bitcoin Key" is my Public Key on which I got my bitcoin.

Is there any other way to get my Bitcoin back if I didn't get my original wallet.dat of Bitcoin Core?

If you lost your wallet.dat, have no backups or dumps of it, I'm afraid there is no way to recover your coins.

# Recovery after losing wallet.dat and formatting hard disk

(Asked by: username_0 on 2021-05-02)

I have received the bitcoin way back in 2013 in Bitcoin Core. At that time I don't know about the importance of wallet.dat - I have formatted my hard disk and install Bitcoin Core again in 2017 but there it didn't show my Bitcoin in my balance. I have my Bitcoin Key.

I meant "Bitcoin Key" is my Public Key on which I got my bitcoin. Is there any other way to get my Bitcoin back if I didn't get my original wallet.dat of Bitcoin Core?

How can I get my bitcoin back?  
How can I get to know my Private Key?

Your money is lost without at least one of

* a backup of important data from the hard disk before it was formatted
* a backup of the `wallet.dat` file
* a note of the private key

There is no way to recover the private key from other information. If there was, Bitcoin would be completely unsafe and unusable.

That's what your `wallet.dat` contained. You cannot get that back if you've lost your `wallet.dat`. Otherwise, Bitcoin would be worth $0 as anyone could just "make up" private keys with any amount of Bitcoin.

Since the `wallet.dat` was long deleted, re-installing Bitcoin Core is insufficient—there is nothing left for Bitcoin Core to guess your old key.
