Everywhere else there is a distinction between virtual currency and real currency. This line just says "currency".   It is quite vaque in that it could say "if the person accepts (Bitcoin) from one person and transmits it(Bitcoin) to another person as part of the acceptance and transfer of...value (that substitutes for currency)."  Would that mean that every node on the network transferring bitcoins from one person to another is an "exchanger and a money transmitter"?
