That makes a lot more sense LOL. Also honestly I don't use either. If I wanna hide my cash, I just buy tutors.
There are two types of bank. Piggy's and Mr Cash (the atm/banker thingy). Piggy's are called PIMD bank in shop, but Mr Cash gets called PIMD bank by players also. I think that's what they meant. They each have a different return rate. ๐
