Hello Mark,

If you sent BTC to your BTC address, they would be in your Abra wallet. If you sent BSV to a BSV address, they would be held by Bittrex but you would be able to see them in your Abra wallet.

However, your funds are sitting on the blockchain and do not reflect in your wallet because you sent BTC to a BSV address, they cannot be recovered and thus have been lost.

Please keep this in mind when sending funds to make sure you are sending funds to the address that coincides with the coin.

We apologize for the confusion, but those funds have been lost.

Best regards,
Ava
