A couple of years ago, there was a crypto project named "MangoCoinz" which allowed anyone to earn crypto by simply walking. The app used the smartphone's pedometer to keep track of the steps taken by an specific person. This encouraged anyone to exercise their body while getting paid in return. While this was great back then, the project is no longer being developed. Something like this would've been great to have in the mainstream world today, but I guess there was lack of demand for it back then.
I'd hope that someday a new dev team takes charge of the "MangoCoinz" project or simply create a fork of their own, to allow people to "mine" crypto by walking. It's completely revolutionary way of doing exercise while getting paid in return. Maybe launching an ERC-20 token with its own app will do the trick? Whichever way it is, I look forward towards the revival of an app that would work just like "MangoCoinz" did in its early days.
Do you think something like this will be viable in the future?

It is really fun to earn cryptocurrency by just walking but it will be very difficult to attract investors in this kind of project because people will just focused in earning cryptocurrency for free that they always keep selling it, without buying it pr investing their money, that is why MangoCoinz failed in the first place.
