Well.. There's a reason why people would let go of those files, and that is bc they have deemed it useless so I don't really see the point of this.
It's either op has actual wallet.dat with funds and private keys in it but it was too difficult to crack or that there's something wrong with it like having no private keys so there's no way to spend those funds. If it's the former, then those two also applies to the one you are gonna be exchanging with...
Are you saying that it's possible to alter a wallet.dat file to remove the private keys and it will still open in Bitcoin Core normally?
The reason I am asking is because I am currently attempting to crack some wallets and as far as I am aware, if I can open the wallet normally in Core, then it must be crack able right? or am I missing something?
Yes, all metadata values can be faked, changed, updated and so on. There is a test wallet, I can send you with all fake values for your validation.
