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.
BTC gold sound new to me and I have no idea what is coming new fork in Nov 2017. some people are afraid if the hard fork in some reason but the Btc community will support them and accept these new altcoin. Don't worry if the price if it is going to decrease it will not affect but you gonna hold you BTC for awhile until the price is pump. Support the new BTC gold it will help to the BTC community.
