What exactly is "Bitcoin Gold" supposed to be? Anyways, spinoffs and altcoins can do whatever they want without hindering Bitcoin in any way. I see no reason to disregard Bitcoin just because it happens that an altcoin is based on its chain up to certain height.
Bitcoin Gold is the gpu version of Bitcoin.
The guy that is promoting it in order to get rid of the "evil asic manufacturers" is actually a big gpu miner .
Basically he wants to take the place of bitmain with a coin that is "more fair" (that is actually what he said so we have a clue about his English skills) to the average miner.
In the end they can make 2 or 5 or 600 thousands clones, if the market decide they hold some value they will be worth something if not, they will end like thousands of coins have in the past.
But I guess by the 6th or 7th coin people will start looking at them like jokes.
