I've did some research. First of Bitcoin Gold is a truly scam. It did not even finished programming and not polished. This coin developed by one man and he did not keep with this date... also he premined a lot... Bitcoin Gold hard fork may never be happen soon... I mean it can be made technically but not publicly. Also check github developer's comment. Also I think Bitcoin gold can not effect to bitcoin price since bitcoin craze itself. I mean people buying bitcoin around the world did not even know about BTG.
