I was browsing the playstore and I seen this suggested app called coin, looked interesting so I downloaded it and did a bit of research and testing, so its a Geo mining blockchain project the idea is for people to use their devices to generate reliable decentralized location information, and rewarding their users.
With the app you are able to get this XYO coins for generating such data as you go around, they sell a device that helps you earn more but that makes me sceptical, and you need to get mine a minimum of 10,000 XYO before you can withdraw it...
The device that they sell that will help you mine more its free but you have to pay for shipping .... so its not that free haha
Hope you got some value from my post,
