Its own currency seems odd, arguments could be made instead for better wallet integration so discreet payments could be made through signal but this would complicate ease of use for people. Also a very slim minority of people would actually perform the action of installing a wallet and connecting it to signal. If signal is your wallet and you are sending signal coins everybody who has signal will be able to receive a payment from you without worrying about installing a wallet separately and connecting it to their account. This is smart from a usability perspective and maybe wallet integration and other currencies will come later. Another reason this makes sense is by controlling the cryptocurrency signal has control over the protocol to ensure it's privacy and anonymity.
