Unlike bitcoin cash hard fork which was directly from the block chain bitcoin gold will be using GPU and an entirly new algorithm then what bitcoin currently uses. But BTG in terms of the currency it looks pretty dead and wont show very much support in the long run.
Don't believe this man. It's nothing but an altcoin that can be mined by using GPU. That's it, then there is nothing makes it special. It's not bitcoin, it's just a regular altcoin. There are already lots of similar ones on the market.
Bitcoin gold is an alt coin. It's mineable and another speculative vehicle like Bitcoin.
