This is double win for the scammer:
They get money for selling the wallet.dat file
They also steal whatever you have in your system once you try to open the wallet.dat file.

I'm a professional mines player. I have made over 500 BTC from playing mines. I won't tell you how or show you evidence of my profit for numerous replies. Invest 0.1 BTC by making an account for me and letting me play on it.
