ZCL has no official dev team currently, which means any fork is unofficial and dubious. It's still being traded so it's safe enough to mine now, I suppose, but personally unless someone officially takes over the project I would steer clear for long term (also the former devs have stated on their Twitter that any forks right now shouldn't be considered legit).

However, forking into a whole new coin is...intriguing. Will be keeping an eye on this, thanks for sharing the link.
