"Bitcoin applies the same philosophy to payment networks. Rather than trying to build every feature into the core protocol, the creator of Bitcoin defined a simple, flexible way to transmit money. The system leaves it to others, like Bitpay, Coinbase and firms that haven't been founded yet, to build secure, user-friendly payment applications on top of that basic infrastructure. It's impossible to predict what those services will look like or whether consumers will prefer them to conventional payment networks. But history suggests that Visa and Mastercard shouldn't get too comfortable."

That shows a very encouraging depth of understanding about bitcoin as a protocol upon which so much can be built. Well done Washington Post.
