The deposit address of my external wallet/exchange keeps changing, why is that?

If your address keeps changing every time that you make a deposit that means that your wallet provider is probably using an HD (hierarchical deterministic) wallet, which changes deposit addresses after each use. Please confirm this with their customer support.


Old addresses should remain usable forever but you should check with your wallet provider to verify this information since we are not familiar with the functionality of other services. Alternatively, you could make a $1 test withdrawal and see if the old address works.
