The reason why zclassic shotup is because it is being rebranded as "Bitcoin Private." Although there is no official news yet rumor has spread that it is happening sometime in Jan 2018. If it pushes through then all well and good because you will probably have mined something valuable. However, if it fails to realize and nothing happens, you will have mined something useless. Its a risk you will have to decide on whether or not you want to proceed with.
That's the nice thing about mining. You pay once for the rig, then you can mine whatever is most profitable. Once it drops on the list, you can switch to something else. I plan to mine ZCL until the fork in the hopes that Bitcoin Private launches because then I will have a fair amount of ZCL by then and the profitability will have come from more than just what I mined. If it doesn't work out, the worst I can say is my mining efforts were LESS profitable (but not nothing) than it could have been and it'll have only been one month. No biggie. I believe the benefit of potential gains outweighs the risk of potential loss in my case. Thanks for your input.
