Prices are quite attractive for many altcoins nowadays (not limited to Bitcoin Gold). It's easier than ever for any newcomer to get into cryptocurrencies without spending much money out of their pockets. While Bitcoin Gold is no different than most Bitcoin forks out there, it has potential for growth if the community and development team continue to work on it. So far, BTG has been quite silent over the past years with only minor improvements to its blockchain network.
I guess that it'll take quite some time before BTG gets noticed in the mainstream world. If it lacks the adoption needed for it to succeed, then it'll be nothing more than just a mere speculative coin. But, if it has prospects for success, then today's prices are a bargain for tomorrow’s influx of steady income.
Nonetheless, BTG's future is uncertain as I've said many times. With all the Bitcoin forks that have emerged since Bitcoin Cash's inception in 2017, it's becoming harder for BTG to maintain itself as a truly unique cryptocurrency for the world. Just my opinion
