I was wondering if coins were included in the present banking system.....
getting one tenth of coins at the end of the day......
and also cracking the vault......
but there should be a limit to the max.coins in the bank....
rate it?

This has been suggested many times by others, and the majority of responses state that the Crack the Safe mini game sounds good, although getting bonus interest added to your coins isn't a good idea, since Da Man had always wanted coins to be hard to get, and that would simply ruin the game even further.

so how about 1% over a week or a month?
