Now THERE is a killer app!

The first fitness tracker to have it's own crypto behind it would just skyrocket.

You would be getting PAID to exercise. For someone like me, training for an ultra marathon, that could be a chunk of change. :-)

A typical training run is around 38,000 steps - a longer run is over 50,000 steps. If I was earning money while I was doing that, you can believe I'd be doing more long runs. :-)
