Is the FemtoStar Credit Token a cryptocurrency?

    No, at least not by any usual definition of the term. While they are
    a digital system used to pay for service, and while they do make use
    of cryptographic signatures for security, FemtoStar Credit Tokens are
    not transacted on a blockchain, cannot be mined, and are not intended
    for use as anything other than payment for FemtoStar service. While
    third-party users are free to buy and sell Credit Tokens at any
    price they are able to, their value in FemtoStar service is fixed.
