Bitcoin is but a digital good, owned decentrally, securely, manufactured non-effortlessly, with current liquidity due to widespread demand - thus having currency attributes.  Other uses includes cryptographic applications like encrypting a message VERY, VERY securely to someone sharing a wallet.dat file and using each key in the wallet.dat file as a one-time password; or signing in to a web service securely by sharing a wallet.dat file with the website.  You can even sign something with your wallet.dat keys and it can be publicly authenticated by the bitcoin blockchain that you as key owner/holder has signed it.
