Bitcoin Gold seems to be the same lineage of Bitcoin Cash and what I mean is it was born of Chinese miners. These guys are up to something and I've placed my bets heavily on them with this coin and Bitcoin Cash.
What I like about Bitcoin Gold is the equihash algo. It is the best algo for NVIDIA chips. And what is set to be released in a few months? That's right, a new NVIDIA chip the Volta. Once it gets released and Bitcoin Gold starts releasing roadmap plans this coin will crush. My hope is that people with NVIDIA chips will prefer to mine this coin as opposed to Ethereum and since it probably has more upside potential in terms of % growth in the short-medium term as compared to Ethereum I can certainly imagine that being the case.
