So i haven't had much time lately to follow this project.  I hold a bit of XBY and haven't gotten a chance to delve that much into xfuel.  So from what i'm gathering is that Xfuel is a direct clone of xby?  The only difference is that it cannot be used to register statics? If I have it wrong can someone can a succinct summary of it?  it seems strange that an additional token would be added to the ecosystem if it wasn't originally part of the initial pitch.
