You can import your old wallet if you have the old recovery information. Your access to the wallet with the old set of keys will still remain as long as you keep the old keys in a safe place to which only you have access. We suggest our users save their old keys as well as their new recovery phrase to avoid losing access to their assets on the blockchain. If you have any questions, please contact support at bttspeed@bittorrent.com
To import your old wallet, please open the Wallet within BitTorrent Speed and click on import wallet
