Coin can do more bad than good Reward system can be good but is can be worst for your phone if your phone dies because of it taking so most of your battery life They should have made the app Lighter and I think background rewards not are good 3 Hours are not good I would make it longer than 3 hours They should has put it in ads Every 170 ads of coin than you get 1 ad for 0.5 mins more on background rewards Than it would not always gives you COIN for ads it would gives you a boost on background rewards add a event for it to gives a users 1 Hour more on background rewards for a day I think is Just Boring because is just mine ads and walk Not like a game uses this type of move Pokémon go has nearly the same thing as coin walk get Pokémon's and walk to gyms and poke shops
