i don't see bitcoin as a currency. it's the strongest blockchain which could be used as means of exchange or transaction. those features are just
some applications of bitcoin blockchain and there should be many others on top of it. as many applications appear, value of bitcoin blockchain increases.
Maybe you didn't consider bitcoin as currency because you didn't see it in real but I don't think so. Bitcoin is just a currency, a digital currency that have its own value same as fiat money. And it can be used in any transactions online accepting this. Yes, it could be possibly a new generation of currency as it becomes widely used by the people worldwide.
