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.
When you created the Bread Wallet, you should have written down some recovery key words. Those key words can be used to recover the private keys that you need to access your BCY.
I don't know anything about BCY, so I don't know which BCY wallets (if any) allow you to import the type of key words that Bread Wallet uses. You'll need to ask in the altcoin sub-forum for help from someone that is familiar with BCY wallets.
Ok, support has given me the same answer in summary:
If you have your private key (I guess it should be the case when using bread wallet, right?), you can implement it in counterwallet and then import the fund from the bread wallet.
If you don't know your private key, you can try to contact the bread wallet support to ask them how to get it.
Please, advise, and will further explain you how to import your funds.
Thanks
