It's not clear to me how I'd exchange my lumens for goods or services. I could imagine transferring some lumens to a friend for my share of dinner, but only if my friend is actually going to want lumens. Even if they're a keybase user, they're hardly going to be excited if I transfer them tokens that they are then, themselves, going to find difficult to exchange for goods or services. If Keybase had to cancel this because all of the people signing up were after the lumens to speculate, maybe they should work on making the currency actually usable and liquid. I'm not interested in speculating; if I could use this to buy something down the supermarket, I'd be very interested.
