Bitcoin Gold seems to have a solid development team, as it has managed to quickly implement an ASIC-resistant algorithm after the release of Bitmain's miners for Equihash. If it remains a GPU-only mineable coin, then it would be much more decentralized in the mining process than both Bitcoin and Bitcoin Cash. However, its success will only depend on the level of adoption it would experience in the mainstream world.
Considering that it has all the same features as Bitcoin, with the differences being an ASIC-resistant algorithm and better privacy, it could be well worth the investment after all.
Nonetheless, do you think Bitcoin Gold (BTG) will have a future or not?

Well, we can not say anything for sure. Bitcoin is the strongest of all cryptos with a huge market presence yet it is taking a lot of time for people to accept it. Bitcoin gold might also need to wait for its acceptance.
