Have anyone heard of Sweatcoin? It is a new app developed by a team in London that rewards people who walk by giving them a cryptocurrency called Sweatcoin.
It can only be mined with outdoor steps when your GPS is on(1000 outdoor steps = 1 SWC). Although it cannot be traded in crypto markets now, it can be used to buy stuff like Amazon coupons, Snapchat spectacles, IPhone SE, Samsung Gear VR, etc.
