Bank Of Springfield Idea. (Savings and investment)

bucks118

I think it would be a great idea if The Bank of Springfield was a little bit more like Cletuses farm, in a way that you can invest money and time for a profit, for example if you were to put in 100,000 for 1 week you get a 5% interest rate 2 weeks 15%, 3 weeks say 30% 4 weeks 50%, 8 weeks 75% and 12 weeks just like corn (90 days) 100% interest rate, I think it would be a good way to gain some cash with out the hassle of tapping especially for new players.
What do you think guys?
