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.
