Walk to make money (some sort of crypyo-coins actually). Sweatcoin is an app that will give you points for exercising outside. Once you download the app onto any device they will begin tracking and verifying your outdoor steps using GPS. Then your steps are converted into Sweatcoins. Their goal is to get people out of the homes to enjoy the outdoors, and they are sponsors willing to pay you for it. With Sweatcoins you can purchase and bid for a good range of items.
