“Divide 72 by your rate. That's when your money doubles. Napkin math.”
The Rule of 72: divide 72 by your interest rate to find how many years it takes to double your money. At 8%, it's 9 years. At Bitcoin's historical average, it's months. The simplest equation in finance, memorized by every investor who's ever done napkin math.
