Bitcoin Private (BTCP) is a proposed "fork" of Zclassic (ZCL), combining the Unspent Transaction Output (UXTO) set of ZCL with the UXTO's of Bitcoin (BTC). The UXTO snapshots are considered the first ZCL and BTC blocks found after February 28th, 5pm UTC.

Bittrex will NOT be supporting the market for Bitcoin Private but due to issues with the Zclassic wallet, we will offer Zclassic holders on Bittrex partial support through claiming and withdrawing BTCP.

Bittrex has shut down the Zclassic wallet for deposits and withdrawals as a significant amount of coinbase transactions and UXTO's in the wallet has led to deposit and withdrawal delays. Please make sure you have cancelled any pending ZCL withdrawals. Bittrex will suspend deposits and withdrawals of ZCL until after the snapshots are complete and the wallet is in workable state.

Bittrex will suspend the Zclassic market approximately 15 minutes before the snapshot time and perform an on-exchange snapshot of ZCL balances. The market will re-open after 5pm UTC once the on-exchange snapshot is complete.

Bittrex will make all reasonable attempts to credit our ZCL users BTCP but until we have a fully supported wallet, we can not guarantee tokens. We will continue to monitor the state of the codebase and network. Since the ZCL wallet contains a significant amount of UXTO's to clean up and consolidate, we anticipate that BTCP will be available at least a week from the time of the BTCP network launch.

Bitcoin balances will NOT be credited BTCP.

Additional technical notes:

The upstream project Zcash does not have these wallet issues as we worked closely with their team to implement the following changes:

Zcash GitHub issue 2446 - Add field indicating coinbase tx in output of listunspent

Zcash GitHub issue 2448 - Add an RPC function or flag to create a shielding transaction that only contains coinbase

The Zclassic codebase is behind the upstream Zcash codebase so it does not have these changes implemented. We have requested that the Zclassic team test and implement these changes ASAP.
