What happens with btcz if ZEC corp close their code from other team for forks? I suppose there are no developpers in bctz team who will be able to develop their branch.
Why for btcz was choosen equihash? Its the most slack-baked of all algorithms. It have security and usablity problem in wallet system, Z adress are not usable for most situatuon...
The ZCL project was abandoned in favor of the much more robust (IMO) and professional coin ZenCash (ZEN). All of the developers moved to the new coin and the ZCL blockchain was orphaned in favor of the ZEN fork.
