First off all this not financial advice 
Don't worry even if this advice no one will Buy your story. Though I believe that Fork Bitcoins are promising specially when time comes that all Bitcoins is already mined yet the chance of defeating bitcoin in future is far from reality.Haven't head of Bitcoin gold before but nevertheless it is quite erroneous to have that specially that we have Bitcoin. Its just a scam I guess using the name of Bitcoin as their bait.
Maybe not a scam but a desperate move from the dev of this clones.
