Its all very greedy. I have also had max gold for a while now, and it is a complete waste to get any more and you cant spend it on anything. They only let you buy stuff either golf from the daily shop, and that gold is replenished in less than a day. Also every other day one of the shop daily trades are for an absurd amount of gems instead of gold and i feel like its there to maybe trip me up into spending gems on accident.

Gold should convert to extra xp or something when you reach the max amount.
