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?

Yes, now the situation in the crypto market is very complex. But I believe that with time the market will be able to recover and reliable coins will begin to rise in price. One of my favorite investment areas is now becoming Bitcoin Gold. The coin has an excellent development potential, so I regularly invest money in its purchase.
