Kinda interesting but in my own opinion, it is really a great way to innovate mainly you can actually mine and earn crypto by just walking and it is a great way to encouraged people to do exercise everyday. But on the otber hand, this kind of projects will not make any good investment Maybe the reason why this mangocoinz is dead today because it has no volume that no one is trading with it. So leaving one alts name that mamy investor might interested amd this alts called Aci coin.
