Fact: The United States could be getting rid of the penny. If this happens, just find a cutable item worth 5 cents (-$0.05); If you cut the item in half, you will get two pieces worth 2.5 cents, but since you can't have pennies, the price is rounded up to the nearest nickel, so you will have 10 cents worth of that item. Sell the item for its intended value. You will get +$0.10. You have obtained $0.05 profit, which makes this an instant 100% return. Repeat until rich or loophole patched. PROBLEM, STONK EXCHANGE?
