The cap should be per player, not per realm. Putting a maximum of 100M coins to be shared among players, regardless of the amount of players participating, and regardless of the banish size, does not seem to make sense.
The individual cap should also raise with the size of the banish.
50M banish: 10M coin cap
250M banish: 20M coin cap
1.25B banish: 40M coin cap
6.25B banish: 60M coin cap
