So if i only have .5 zcl I won't get any bitcoin private unless i get another .5 zcl before the 28th of feb?
yes, when hard fork happens, snapshot for all ZCL and BTC will happen. Anyone with a ZCL or BTC in a supported wallet or stock will get Bitcoin Private (BTCP) with a 1: 1 ratio. For example, if you have 5 ZCL and 0.1 BTC, you will receive 5.1 BTCP.
I'm sure that is incorrect. Even if you have .1 ZCL when the fork happens you still get .1 BTCP. You don't have to have a full coin to get BTCP. Same goes for BTC to get BTCP.
