From what I heard btc gold sounds kind of shady to me(pre-mine, lack of information).
If it works and it is worth a significant amount of money then I'm afraid people will start doing hard forks for no reason and that the btc community will just support them and put pressure on exchanges to accept these new coins.
I agree with you. Really it's a matter of concern. Yes, it is possible that people will start doing hardforks without any reason for accepting their new coin. And I think that will not good for Bitcoin.
