> Unfortunately, for transactions between two Bitcoin addresses that are on the Coinbase network, Coinbase will perform an internal transfer of funds. The transaction is never pushed to the blockchain, avoiding the need to pay Bitcoin fees, and making payment confirmation instantaneous.

Wait... what? how does this work? didn't the wholepoint of using Bitcoin is that there is a public ledger for every move? Looks like Coinbase find a way to act like a real bank on the bt network.
