Walk the walk, wacky Wednesday invention

I've noticed the success of Pokemon Go, and it has made me think of a new invention. This idea would be an app. The app would pay a certain amount in a form of credit for a distance walked. It would track the distance o make sure that you aren't cheating. But the kicker is, my idea would be that in the map, different location would spawn, and they would pay out different amounts of money. This way, people who don't walk much can play too. Also, once say, 5 people collect a prize, it vanishes.

If you walk the walk can you talk the talk.
