The time of Zclassic seems to be nearly gone, but at least there are still some communities that stay but if there are no more additions in the future I think it will begin to be forsaken too.
There have been many issues surrounding Zclassic, it still stands true to the original cryptocurrency and blockchain philosophy, unlike other popular peers. Its increased privacy features and mining potential can make it a good investment, but if a strong and cohesive development team is not behind the project, then you should start looking into other coins.
