STEPN (GMT) is not the first token to introduce the move to earn concept, I first heard about this concept from Izetex some years ago and I actually downloaded their app then and earned some of their tokens, I eventually got tired of following up but I don't hear much about them later.

Also COIN app has been on Google PlayStore for some years now where you can earn XYO for moving around while leaving the app running. I however do hope that STEPN has a long term plan to survive on this model and that it doesn't fade away. I'll like to see Cryptocurrency startups successful to encourage more people to come in.
