We will see this in the future, and I think if the teams are solid, then they will work serious with their project and will make Bitcoin Gold as one of the valuable coins and profitable coin. But it will need time before we see this is happening and it's not as easy as they imagine because Bitcoin Gold needs to compete with the other coins.
That's certainly true, mate. It won't be easy for Bitcoin Gold to compete with other cryptocurrencies, as they have implemented several advanced features. There is nearly one altcoin for nearly everything in life such as privacy, smart contracts, store of value, and even passive income. Since Bitcoin Gold is a fork of the original Bitcoin, it shares many of the characteristics of its father. The only difference is the type of PoW algorithm used which is much friendlier to GPU's than Bitcoin's SHA-256 PoW algorithm.
However, there are other altcoins which are easily mineable with GPUs and are ASIC-resistant like BTG. Ravencoin is one good example of an altcoin which is ASIC-resistant and mineable by anyone with a GPU. As such, Bitcoin Gold needs to deliver something innovative to the blockchain industry, or it will simply fail over time as user interest decreases over time.
Nevertheless, there are only two Bitcoin forks which have remained solid for some time. Such forks are Bitcoin Cash and Bitcoin Gold. However, only one of them might survive while the other goes down the drain. Only time will tell us which fork could maintain development and innovation within the mainstream world. Just my thoughts
