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.

How can I get to know my Private Key?

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.

  • If you lost your wallet.dat, have no backups or dumps of it, I'm afraid there is no way to recover your coins. – Pieter Wuille May 02 '21 at 06:35

there is still a minor hope for you this is the software which recover the data even from the formatted hard drive if you successfully recovered your wallet.dat file then replace the file with your new wallet.dat of bitcoin core which has Zero balance.
