That is correct! This is a special BC Vault Bounty Wallet, that is included in all sold BC Vaults. If you manage to gain access to this wallet (remember, you need wallet password and PIN), you are free to take 1 BTC! Let the games begin :)

In BC Vault Desktop Application from version 1.2.x on, this wallet balance and transactions will be ignored and will not show up in your portfolio. Should you wish to hide bounty wallet, you can do so under "View all wallets" (use "HIDE" function).
