Gym rewards

Is there anyway we can get something done about this coin thing because some of us have Pokemon in there for days and I dont see it as fair that we only get 50 coins period for that Pokemon I mean whats the point if you think about it to have in a gym for almost a week. Other than that the only other complaint I have is the game likes to force close alot
