The Bitkey wallet is designed to generate a new address for each new transaction. If you generate a new address and don’t use it, your Bitkey wallet will continue to present this address until it has been used. This makes it more difficult for your payment history to be tracked on the blockchain.
Tip: To protect the privacy of your transactions, it’s recommended that you generate and use a new address anytime you plan to receive funds. See How do I receive bitcoin? for more information.
