I was called by a person from Apple: App was rejected by Apple because "...it involves intermediate currency..."
I've asked why Apps such as PayPal and Venmo are accepted and he replied that he "does not have time to elaborate"
I then asked if they allow just a console to a remote node (not located on iPhone) and he said that this will also be an App that involves intermediate currency and there for will not be allowed...
Not good. This is why a closed ecosystem like the Apple app store is not a good idea in the first place...
