Be wary of PMs requesting the key/wallet.dat specially from
negative trust members and newbies.
Here's some info regarding restoration/recovery that you can try yourself:
If it was named with ".
dat" extension ex. wallet.dat, it could be from bitcoin core or older version (
Bitcoin Qt).
Regardless of the wallet version, it should be able to run with the latest version (if not, old versions are listed here:
bitcoin.org).
- After installation, copy the wallet.dat to your %appdata%/Bitcoin
- Run and open the wallet, click help, then debug window->console
- Type: walletpassphrase your-wallet-passphrase 300
- Type: dumpprivkey <your bitcoin address>
- Import or Sweep the key(s) to Electrum for faster access, instead of waiting for the wallet to sync (200gb of data+verification)

If it was
Electrum, it should be a file without an extension with a default name of wallet_1 or wallet_default (
or your picked name).
Recovering it is a breeze as long as the passphrase is correct.
Download Electrum stand-alone:
electrum.org/#download.
Open the exe, then browse to the location of the wallet file and open it.
Your Bitcoins should show up after syncing the block_header (
5-20minutes).
