you will ALSO receive a 1:1 amount of ZEN. So, if you have 1000 ZCL before the hardfork, you will have 1000 ZCL after the hardfork plus 1000 ZEN. ZCL will continue to exist.
Wow, it is great! Now I get it, thank's all for clearing

Just keep in mind that no one knows what ZCL will be worth after the harfork, or how much ZEN will be worth when in comes into existence. If everyone just dumps their coins, both ZCL and ZEN may be close to worthless, at least for some period of time.
Will have to think about what mining strategy to use on this. After the fork, I will probably point half my machines at Zen and leave half running on Zclassic. Zclassic will have a lower hash rate, so I should be able to pick up more blocks on it if other people move their miners over to Zen.
