Sorry in advance if this is not where I am suppose to write this since I hardly come on the forums

I want to know if adding a bank to this game would be good for the game. Whether it is for making our coins or like ingots grow. I seen games like Game of War where you put a certain amount of gold or ingots and wait for a certain amount of days before getting more gold or ingots. I can't see how Konoha can not survive without some sort of banking system...
