BitCoin not being a real currency probably jumps over their legalese a little and would allow somebody to make an in-app payment without giving Apple their "dues".
I frankly think the whole situation is ridiculous. God knows how Apple (and the others, to be fair) justify hogging 30% developers' revenues but conversely, what idiots are going to put their livelihoods on the line with something as changeable as BitCoin? It's not just that its rate can crash but that Apple can very swiftly make you an ex-developer.
