Pokemon Go coin system
I would suggest a system with the following specification
A total limit of 50 coins. This seems fair, let’s keep it, but let the players choose how to get them. Don’t impose individual limits on quests or defending a gym.
Give coins per quest. You should get some coins for completing a quest, don’t make it all or nothing.
Make the coin quests field research based. For example 5 coins per completed Field research. That gives an incentive to complete more Field research. It also allows the player to skip a quest that the are unable to complete.
Accelerate coin gains for defending a gym when the gym newly is defeated. 1 coin every 3 minute for the first 30 minutes to make sure capturing and defending a gym is worth it in high turnover locations. This accelerated coin gain should probably be disabeled outside of Raid hours so that the gym turnover slows down during night time.
With these changes, I think the coin rate Niantic suggested initially implemented with 2 per hour, is correct.
