But bitcoin can't be transferred and traded. Nobody accepts it as payment, because its value is too volatile, speculation-driven, and nobody wants to spend it, because it is deflationary. And that's not even considering the fact that it can only be transferred at around 6 transactions per second, less than 1/10,000th of the transaction volume of Visa.
