Can I implement a E-Wallet recharge logic for iOS like this (Without being rejected by Apple)?

My proposed steps: Upon using an app, you shall register account by using either Validated Email / SMS / Facebook. Upon registration success, you have $0 dollar in your wallet. When you are shopping, you click to buy an item The app warns you that your account has no balance in your wallet. You may choose from ways below to receive a disposable/one-off recharge link Email SMS Facebook messenger User shall need to leave the app in background, go to check new email / SMS / Facebook Message to look for the link. By clicking the link , user shall be redirected to a website instructing users to deposit an amount determined by user (e.g. 1 E-Dollar : 1 $USD) by Credit Card / Paypal information. Upon payment success, server shall send a confirmation push notification to the app. My questions are: 1. Is the E-wallet dollar considered by Apple as a kind of virtual goods? 2. Is the above transaction scenario valid? 3. How many chances does this app be rejected by Apple?
