I just thought of a crazy idea now that Bitwalking doesn't seem to be popular in the US and Burningman went short.
So, what if the steps themselves were a type of offline, Bluetooth-transferable coin? For example, Jogger A has a watch full of 53,453 total steps. Jogger B only has 2,536, but wants to sell his iPod to Jogger A for 39,000 steps. The Bluetooth transfer is made, and now Jogger A's watch says 14,453 steps, while Jogger B's watch says 41,536.
Any questions?
Interesting concept. You can't create value out of
nothing, but a step requires
something.
