Not really because i cant see my current actual BNB average.
Before it was posted beside the cardlevel but not anymore, maybe they moved it somewhere else.
The best thing to do is to chat this to their support, they're easy to contact and the live chat is responding quickly. You tell them this and for sure that they're going to give you the appropriate page that you really need. They've been helpful to me when I've approached them a couple of times that's why I like this exchange at all.
