One of the members asked me if I can store his money like bank usually does and it got me thinking that it would be a great idea for players to save some of their earnings in a bank and can give interest on that saving. The interest would come from the extra interest on loans interest. Also they can withdraw money anytime they like.
This could be a great business venture also. This way players can so get the essence of saving in real time and having some backup at a crucial time too.
