    This is a bit misleading - doing this would almost certainly require that both parties recognize the fact there is a third party at play.

      I think the example they gave with a reverisble credit card charge was pretty good: If you buy from store using your credit card, you can ask the credit card company to reverse the charge if there is a problem.

      This is what you can do with bitcoin, if you and the seller agree on a third party.

      But, once the third party approves the bitcoin transaction, it can no longer be reversed. Whereas a credit card company can reverse a charge long after the payment has occurred.
