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.
If you are going to find a better option or the best alternative currency in transaction the nest thing to consider to used is of course the crypto-currencies which is a part of the technology. And the best form of crypto-currency is no other than the Bitcoin. So I agree to the point that is is just not a money itself but a better or the best form of money which can make transaction fast easy and reliable.
