The wallet is bread and this is Bittrex's support response:You have sent BCY to a BTC address, these wallets have addresses that validate to each other, but the wallets are not compatible for receiving coins. You'll need to research how to remove a private key from a Bitcoin address and import it into a BCY wallet to recover these coins. You may want to contact someone from the BCY community for help.  We can be of no further assistance on this issue.
