After purchasing Wrapped XEP tokens (WXEP) you can, and should, store them in a wallet which you directly control. This way you make sure that only youself maintain access to your holdings.
Since WXEP is running on the BNB Chain, you can use any WXEP wallet which is able to store BEP20 tokens. This may include smartphone wallets, desktop computer wallets, CLI wallets, and hardware wallets.
