I believe that the statement: "bitcoin is new kind of money" passes the
duck test.
Bitcoins function as money (they're a unit of account, a medium of exchange, and a store of value), and if PayPal started allowing Bitcoin transactions tomorrow I'm certain they'd treat them as Just Another Currency.
If you like, call it a commodity, but I think all you'll accomplish is confusing potential users who might think they'll end up getting pork-bellies delivered to their porch if they don't get rid of their bitcoins.
that's right, I'm as bad as bitcoin is a new currency but it's classified as a digital ungodly eye that its use is still limited yet all of them can use it.
