DO NOT TRUST ANY OTHER INFORMATION ABOUT WALLETS THAN WHAT IS POSTED ON OFFICIAL BTCP PAGE!
Seems like scammers are trying to get your ZCL / BTC private keys, so they can claim your wallet as their own.

There will be official confirmation from BTCP dev team after wallet has been launched. Keep cool and wait for fork and mainnet launch. Before this you cannot get your BTCP and there won't be official wallet.
