I ask in newbie chat how its increase someone told me its 1$ for 1000 (cash in bank) but my friend has 39000 in bank has 412 intrest i have 140000 in bank i get 141 why?

If you have $50.000 and under you get 1% interest, so if you have $49.999, you get an interest of $499. If you have $50.000 and more you get 0.1% interest.
(Correct me if I'm wrong)
