Hi teknonix I had a situation similar as I lost about 2 to 5,000 btc but I still have my wallet file. Is there anyway you can help me get my bitcoin back. I can give you tip . Please say.
To you and any other newcomer reading this:
Do not share your wallet file with strangers. That's how you get your coins stolen.
