The bitcoin.com wallet allows privacy minded users the ability to generate a new address using the circular arrow icon to the bottom left corner of the QR when users are inside the Receive screen. Some users may prefer new addresses to be used for each receive of coin. While others may want to track a single address and the coin it receives for simpler accounting. The Bitcoin.com wallet supports both of those use cases.
To protect your privacy, the Bitcoin.com wallet generates a new address every time you receive funds.
Note that all old addresses are securely saved in your wallet, so you can still receive payments to an old address generated by your Bitcoin.com wallet.
All bitcoin transactions are public, traceable, and permanently stored in the Bitcoin network. For these reasons, Bitcoin addresses should only be used once and users should be careful not to disclose their addresses. When addresses are re-used, it becomes easier for third parties to track your activity and determine how much money you have and what you are using it for.
