Price of bitcoin gold when it is released is probably sitting at hundred dollars considering BCC started somewhere around that price. People wouldn't be mining it unless developer fix some on his codes. It might be the other way around if bitcoin gold have proved it's profitability in the future. If the later will happen. Miners might start to mine it 1-3 months after the fork and as time pass people will stop mining it like how bcc miners decrease day by day.
