This is funny story
My city is ruled by instinct (4/5 gyms)
But they have "friends" in other teams.
In old days these "friends" could get easy coins from their gyms and then instinct obviously takes the gyms back, but "friends" still got coins.
But imagine situation now! :D
Now only team who can keep pokemons inside earn coins :D
If instinct want other players collect coins, they will lose coins by themselves :D
I bet their friendship will take big hit now:
