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?
It's a 1:1 match. If you have .5 ZCL when they do the snapshot on Feb 28th you'll get .5 BTCP once the project goes live. Likewise any BTC you have in a private wallet will also be matched 1:1 with BTCP.
