There's a difference not noted: credit cards give you credit, which is why you have to apply for them. When you use one, you aren't transferring your money to someone else, you're transferring a third party's money, with a promise to pay them back later. Each transaction is a tiny loan. In the bitcoin scenario described, it is more like a cash transaction, you have to have the bc in your wallet. And, of course, bc is way more complicated than a cash transaction.
