My Suggestions For New Update.
I think having a cap is all well and good. Perhaps keep it low, lower the amount of coins per hour, but have an item that drops on a rare occasion from gyms that increases the cap or coin amount for a 24 hour period. If this item was only available from team gyms or leveled up gyms it would make it that much more prudent to take and hold gyms.
The item would need to be a very rare drop to justify the 24 hour period increase. And probably only allowed to have one at a time in any case.
Perhaps there are different tiers of this item, like the potions, which double, triple, or quadruple the 50 coin cap during its active period.
Any thoughts?

50 is a ridiculously low cap when raid passes cost 100 each. It should go back to 100, and gyms should pay out 3 coins for the first hour(at 10, 30, and 60min) and 1 coin for each additional hour. The coins should be paid at midnight, unless your Mon comes back sooner.
All this is secondary to fixing gym lag and the new dodge bug that can happen even if you don't dodge. Having gyms nearly unplayable will kill the game faster than the coins situation.
