With bank being released in version 8.1 I was very excited, but, to my dismay, at max tier bank you only gain 1.2k per day in interest. However, it takes over 2,000,000 dollars to get there. What this means is it takes over 2000 days to return what you invested. This doesn't even include any profit! Version 8 is not going to last over 2000 days. So that 2,000,000 dollars you spent, you can say bye bye to that. I recommend increasing the interest rate so that as an investor you are not scammed out of your millions of dollars.
